Release Notes for Cisco Secure ACS for Windows Server Version 3.2

These release notes pertain to Cisco Secure Access Control Server for Windows Server (Cisco Secure ACS) version 3.2.1.

New Features

•

PEAP support for Microsoft Windows clients—Cisco Secure ACS 3.2 adds support for Microsoft PEAP supplicants available today for Windows 98, NT, 2000, and XP. The Microsoft PEAP supplicant supports client authentication by only MS-CHAPv2 compared to Cisco PEAP supplicant (available through Cisco Aironet wireless adapters) which supports client authentication by logon passwords or one-time passwords (OTPs). Unlike Microsoft PEAP supplicant, Cisco PEAP supplicant provides support for one-time token authentication and powerful extensibility of non-MSCHAP end-user databases such as LDAP, NDS, and ODBC. Cisco Secure ACS 3.2 allows selection of Microsoft PEAP and/or Cisco PEAP from its EAP Configuration page. PEAP is an Internet draft standard in the IETF PPP working group.

•

LDAP Multithreading—Cisco Secure ACS 3.2 can process multiple LDAP authentication requests in parallel as opposed to the sequential processing mechanism employed in pre-3.2 versions. This feature greatly improves Cisco Secure ACS performance in "Task-hungry" configurations such as in Wireless deployments.

•

EAP-TLS Enhancements—EAP-TLS enhancements in Cisco Secure ACS 3.2 further extend Cisco Secure ACS PKI capabilities. EAP-TLS authentication against ODBC user databases, and EAP-TLS silent session-resume support are among the newly added capabilities. Similarly to the PEAP silent session resume, EAP-TLS silent session resume prevents users from re-authenticating during a RADIUS session timeout. This is particularly advantageous in wireless applications where users are continually moving. The duration of the EAP-TLS silent session timeout is configurable from Cisco Secure ACS GUI.

•

Machine authentication support—Cisco Secure ACS 3.2 adds 802.1X machine authentication option using either PEAP with MSCHAPv2 implementation (PEAP-EAP-MSCHAPv2) or EAP-TLS. Machine authentication is used at boot time to authenticate and communicate with Windows Domain Controllers when connecting to 802.1X secure ports. Machine authentication allows pulling down machine group policies from Windows Active Directory independently of a subsequent interactive user authentication session.

•

EAP mixed configurations—Cisco Secure ACS 3.2 supports the following EAP types:

Cisco Secure ACS 3.2 allows flexible EAP settings—one or several EAP types can be selected concurrently—enabling Cisco Secure ACS to intelligently process EAP authentications depending on the 802.1X supplicant.

•

Accounting support for Aironet—Cisco Secure ACS 3.2 supports user-based accounting from Cisco Aironet wireless Access Points when Cisco Secure ACS is configured to recognize them as RADIUS (Cisco Aironet) AAA clients.

•

Downloadable access control lists for VPN users—Cisco Secure ACS 3.2 extends per-user access control list support to Cisco VPN solutions (in addition to the current support for PIX Firewall solutions). With this option, administrators can define access control lists, for users of groups of users within the Cisco Secure ACS HTML interface.

Tip

An easy way to distinguish whether a version of Cisco Secure ACS supports only Cisco PIX devices with downloadable ACLs is to determine the name of the downloadable ACL feature in the Shared Profile Components section of the Cisco Secure ACS HTML interface. In Cisco Secure ACS 3.0 and 3.1, that feature is named "Downloadable PIX ACLs", indicating the limitation of support to PIX devices. In Cisco Secure ACS 3.2, the corresponding feature is named "Downloadable IP ACLs", reflecting the expanded support.

HTTPS Support Change and Management Center Applications

Cisco Secure ACS version 3.1 introduced support for HTTPS to protect administrative access to the HTML interface. In response to a problem discovered in Cisco Secure ACS 3.1 (see bug ID CSCea40150 in Table 4), Cisco Secure ACS does not allow HTTP and HTTPS to function simultaneously.

Multi-device management applications, such as Management Center for Firewalls, can be configured to use Cisco Secure ACS for authentication of administrators and authorization of their actions. Communication between early versions of multi-device management applications and Cisco Secure ACS requires HTTP. If you enable HTTPS in Cisco Secure ACS 3.2, communication between multi-device management applications and Cisco Secure ACS fails.

If you use Cisco Secure ACS with a multi-device management application that is not yet capable of HTTPS for communicating with Cisco Secure ACS, you must disable HTTPS in Cisco Secure ACS; otherwise, integration with Cisco Secure ACS fails.

Note

Beginning with version 2.2 with Service Pack 2, CiscoWorks supports HTTPS; therefore, multi-device management applications using CiscoWorks 2.2 with Service Pack 2 or later are designed to communicate with Cisco Secure ACS using HTTPS.

Changes to Token Server Support

Token server support in Cisco Secure ACS 3.2 is identical to that in Cisco Secure ACS 3.1; however, if you upgrade from Cisco Secure ACS 2.6.4 or Cisco Secure ACS 3.0.2 and you use token server databases, you should understand the changes to token server support that we began with Cisco Secure ACS 3.0 and completed in Cisco Secure ACS 3.1.

Beginning with Cisco Secure ACS 3.0.1, we supported CRYPTOCard token servers using a standard RADIUS interface. Cisco Secure ACS 3.1.1 extended the use of RADIUS to all token servers except RSA SecurID. For RSA SecurID, the vendor-proprietary interface is used.

If you upgrade to Cisco Secure ACS 3.2, the installation program may prompt you for information about token servers, depending on the version of Cisco Secure ACS you are upgrading from and the token server databases detected by the upgrade process.

•

If you are upgrading from Cisco Secure ACS 3.0, the installation program prompts you for information if you have one of these token servers:

•

If you are upgrading from Cisco Secure ACS 2.6, the installation program prompts you for information if you have one of these token servers:

With this information, the installation program replaces the older token server configuration with a new one that uses the RADIUS interface of the token server. For more information about RADIUS support by your token server, see the applicable token server documentation.

Note

If a RADIUS-based token server, such as CRYPTOCard, runs on the same computer as Cisco Secure ACS, make sure that the token server uses UDP ports different from the ports used by Cisco Secure ACS to receive RADIUS requests. For information about RADIUS ports used by Cisco Secure ACS, see User Guide for Cisco Secure ACS for Windows Server. For information about RADIUS ports used by a token server, see the applicable token server documentation.

Evaluation Version

The evaluation version of Cisco Secure ACS 3.2 provides full functionality for 90 days after the date of installation. This allows you to use all features of Cisco Secure ACS 3.2 while determining if it suits your needs. The evaluation version of Cisco Secure ACS 3.2 will be available within 30 days after the release of the commercial version of Cisco Secure ACS 3.2.

The evaluation version of Cisco Secure ACS 3.2 can be distinguished from the commercial version in the following ways:

•

The Windows Control Panel Add/Remove applet indicates that the Cisco Secure ACS installation is a trial version.

•

In the administrative interface of Cisco Secure ACS, the word "trial" appears on the title of the initial screen.

When the evaluation period has elapsed, the CSRadius and CSTacacs services fail to start. You will receive a message upon accessing the Cisco Secure ACS HTML interface notifying you that your evaluation period has elapsed.

Purchasing the Commercial Version

Please contact your Cisco Sales Representative(s) to inquire about purchasing the commercial version of Cisco Secure ACS. To purchase the commercial version of Cisco Secure ACS 3.2 online, use the following URL:

Upgrading to the Commercial Version

Note

To avoid the issue documented in CSCeb34179, we recommend upgrading to the commercial version before the 90-day evaluation period has passed. For more information about CSCeb34179, see Table 3.

After purchasing a commercial version of Cisco Secure ACS 3.2, you can upgrade your Cisco Secure ACS server from the evaluation version to the commercial version by installing the commercial version over the evaluation version. For information on installing Cisco Secure ACS 3.2, follow the instructions in Installation Guide for Cisco Secure ACS for Windows Server, version 3.2.

Limitations and Restrictions

Interoperability Testing

Cisco Secure ACS has not been interoperability tested with other Cisco software. Other than for the software and operating system versions listed in this document, we performed no interoperability testing. Using untested software with Cisco Secure ACS may cause undesired results. For the best performance of Cisco Secure ACS, we recommend that you use the versions of software and operating systems listed in this document.

Supported Upgrade Versions

We tested upgrading to Cisco Secure ACS 3.2.1 from the following previous versions:

Supported Operating System

Cisco Secure ACS for Windows Servers 3.2.1 only supports two versions of the Windows 2000 operating system, as listed below. Both the operating system and the service pack must be English-language versions.

•

We have not tested and cannot support the multi-processor feature of Windows 2000 Advanced Server.

Upgrading from Windows NT 4.0

If you are upgrading from a previous version of Cisco Secure ACS that is running on Windows NT 4.0, you cannot upgrade the operating system to Windows 2000 Server. This is because the setup program for previous versions of Cisco Secure ACS detected which Windows operating system the computer used and customized Cisco Secure ACS for that operating system. As a result, upgrading the operating system to Windows 2000 Server without taking the necessary steps causes Cisco Secure ACS to fail.

We last published information about how to upgrade the operating system of the computer running Cisco Secure ACS to Windows 2000 in the documentation for Cisco Secure ACS 3.1. For more information, log in to Cisco.com and select Products & Services > Security and VPN Software > Cisco Secure Access Control Server for Windows > Technical Documentation > Installation Guides > Installation Guide for Cisco Secure ACS for Windows Server > Installation Guide for Cisco Secure ACS for Windows Server 3.1.

Known Problems in Cisco Secure ACS Version 3.2.1

Table 3 Known Problems in Cisco Secure ACS for Windows Server, Version 3.2
Bug ID	Summary	Explanation
CSCdu48120	CSNT error occurred during the move data process	When Installing Cisco Secure ACS, you may see the following error: `An error occurred during the move data process: -115` followed by several other errors, such as: `Cannot run command D:\Program Files\CiscoSecureACS vx.x\UtilsCSUpdate -install CSAuth - The system cannot find the file specifiedCannot run command D:\Program Files\CiscoSecureACS vx.x\UtilsCSUpdate-install CSLog - The system cannot find the file specifiedCannot run command D:\Program Files\CiscoSecureACS vx.x\UtilsCSUpdate-install CSRadius - The system cannot find the file specified` Workaround/Solution: Delete pdh.dll from the Windows system32 directory, then restart the installation.
CSCdv35872	Insufficient length for NDS context entry	When a Novell NDS database configuration in Cisco Secure ACS has a context list greater than 4095 characters long, editing the NDS configuration page results in incorrect HTML in the browser interface. Workaround/Solution: Use a context list no longer than 4096 characters.
CSCdv86707	User Data Field name is not replicated	Changes to user-defined fields in user records do not appear to replicate. After the user-defined fields are changed in the Interface Configuration section on the primary Cisco Secure ACS server and replication succeeds, the secondary Cisco Secure ACS server does not display the changes to the user-defined fields in the HTML interface. Workaround/Solution: The changes to the user-defined fields do replicate successfully; however, to see the changes on the secondary Cisco Secure ACS server, restart the CSAdmin service.
CSCdv86708	HTTP Port Allocation is not replicated	Changes to HTTP Port Allocation settings do not appear to replicate. After the HTTP Port Allocation settings are changed on the Access Policy Setup page in the Administration Control section on the primary Cisco Secure ACS server and replication succeeds, the secondary Cisco Secure ACS server does not display the changes to the HTTP Port Allocation settings in the HTML interface. Workaround/Solution: The changes to the HTTP Port Allocation settings do replicate successfully; however, to see the changes on the secondary Cisco Secure ACS server, restart the CSAdmin service.
CSCdy51214	fail to delete aaa server when its in sync table/aaa server side	A AAA server cannot be deleted from the "(Not Assigned) AAA Servers" table in Network Configuration if the Synchronize"= list under Synchronization Partners on the RDBMS Synchronization Setup page is empty. An error message "x.x.x.x can not be deleted since it is an synchronization partner" appears. Workaround/Solution: Move any other AAA server to the Synchronize list, then delete the AAA server.
CSCdy59706	CAA messaging wont work with ppp callback and callin authentication	When having ppp callback and only callin is authenticated (ppp authentication pap chap callin), then messaging to the CAA client will fail with all aging rules selected in ACS. This is a documentation bug, the above won't work without changes. Workaround/Solution: Either remove the "callin" keyword to enable authentication for callin and callout (callback in this scenario), or disable callback altogether.
CSCdx19854	Memory check for certificates in https transport is required	When you select the "Use HTTPS Transport for Administration Access" check box on the Access Policy page and more than two HTTPS sessions are active, the following error is presented: `Can't initialize HTTPS transport: too many active HTTPS sessions` SSL Admin design does not enforce a restriction that prevents the modification of Cisco Secure ACS certificates so that there are not more than two certificates in memory at once. Instead Cisco Secure ACS prevents the initialization of HTTPS when more than two HTTPS sessions are in use. Workaround/Solution: Reduce the number of concurrent administrative sessions to two or one before attempting to enable HTTPS using the new certificate.
CSCdz13771	err in csauth in every X min replication-certain flow	Replication fails in very particular circumstances: •Set replication frequency to once a minute •Turn off replication for a specific component, such as the user database. •Modify the database component that is not to be replicated, such as by adding a user. •Turn on replication for the specific component •Replication does not occur because Cisco Secure ACS does not perceive the database as having changed. Workaround/Solution: Restart the CSAuth service.
CSCdz30261	ACS doc does not have examples with product setups	ACS documentation does not have examples with product setups Workaround: Locate deployment guides at http://www.cisco.com/warp/public/cc/pd/sqsw/sq/tech/index.shtml if there is one for the task in question.
CSCdz61464	Solaris Netscape 7.0 - Minor Features Failure	When the administrative browser is Netscape 7.0 on Solaris 8.0, some menus in the HTML interface for Cisco Secure ACS do not work properly. Workaround/Solution: Use a supported Windows browser.
CSCdz61529	Netscape hangs on several times during login session on Solaris	When you use Netscape 7.0 to access the HTML interface of Cisco Secure ACS, the browser stops responding after you access the User Setup page or while trying to add a shared profile component. Workaround/Solution: Use a supported Windows browser.
CSCdz86955	Cannot remove shell authorization from groups display	Shell command authorization remains in the User Setup and Group Setup sections of the HTML interface, even after shell command authorization is disabled in Interface Configuration and the feature is not in use. Workaround/Solution: None at this time.
CSCea50039	T+ authentication errors when stressing TACACS func.	Under heavy TACACS+ authentication load, Cisco Secure ACS incorrectly fails authentication for a very small number of TACACS+ authentication requests. In testing, less than one hundredth of one percent of TACACS+ authentication requests were incorrectly failed. Workaround/Solution: If you have more than one Cisco Secure ACS server available for TACACS+ authentication, distribute TACACS+ authentication load as evenly as possible to all Cisco Secure ACS servers.
CSCea55457	Radius Attributes do not appear in user/group profile page	After you enable RADIUS attributes in the Interface Configuration section of the Cisco Secure ACS HTML interface, they do not appear or appear only partially in Group Setup or User Setup, as applicable. Workaround/Solution: Restart the CSAdmin service.
CSCea60497	no msg in rdbms log on the sync partner about the sync operation	When a Cisco Secure ACS Appliance receives RDBMS Synchronization data from a primary ACS, the RDBMS Synchronization log on the secondary ACS does not record the synchronization event, regardless of success or failure. Workaround/Solution: None at this time. You may be able to deduce when synchronization occurred and whether it succeeded by reading the synchronization logs and reviewing the RDBMS Synchronization configuration on the primary ACS.
CSCea71759	Headline of UCP application stating Cisco Secure ACS	The web pages of the User-Changeable Passwords (UCP) utility have titles and headings that suggest that the user is logging into Cisco Secure ACS for an administrative session. This is not possible from UCP and the headings and titles are erroneous. Workaround/Solution: Educate users about the function of UCP or modify the HTML file contents to change the misleading titles and headings.
CSCea74289	cascade replication due to user pass change-dont work	Cascading replication does not occur when the replication trigger is user password change and the primary Cisco Secure ACS is configured to perform replication manually. Workaround/Solution: Use scheduled replication on the primary Cisco Secure ACS.
CSCeb11405	CS services cannot be started	For Cisco Secure ACS for Windows only, immediately after Cisco PEAP user authentication occurs with a Cisco Aironet AP, the CSTacacs and CSRadius services can't be started. Service logs contain the following errors: `CSRadius could not be started: Could not initialize the Crypto module (service specific error 45)CSTacacs could not be started: Failed to initialise Crypto module (service specific error 69)` Workaround/Solution: Restart the computer running Cisco Secure ACS.
CSCeb15219	Couldnt add NAS filter by CSDdsync	When you attempt to add a network access restriction using RDBMS Synchronization, action code 122 "ADD_NAS_ACCESS_FILTER" doesn't work. When you use the UN variable, the error message "The named user variable cannot be found" is logged even though the user exists in the CiscoSecure user database. Workaround/Solution: Synchronization with action code 122 succeeds after you manually select the "Define IP based access restrictions" option in user profile.
CSCeb16968	MC defined services doesnt function after upgrade	After you upgrade Cisco Secure ACS, authorization support for Management Center (MC) applications, such as Management Center for Firewalls, fails. In the Shared Profile Components section of the Cisco Secure ACS HTML interface, each MC that has registered with Cisco Secure ACS has a set of pages for configuring authorization components. If you access a page for editing or adding authorization components, you see an error message about a missing XML file. Workaround/Solution: You must use CiscoWorks to re-register all MCs with Cisco Secure ACS. Log into the CiscoWorks desktop with admin privileges. Go to Server Configuration > Setup > Security > Select Login Module. Configure CiscoWorks to use the CiscoWorks Local module, and then configure CiscoWorks to use the TACACS+ module. Go to VPN Security Management Solution > Administration > Common Services > Configuration > AAA Servers. Unregister all MCs and then re-register all MCs. Log out of CiscoWorks.
CSCeb34179	CSRadius fail to stop when 90 days evaluation period is over	After the 90-day evaluation period had passed, the evaluation version of Cisco Secure ACS for Windows Server develops problems with the CSRadius service if a RADIUS request is received. The CSRadius service begins to stop but never successfully complete the stop process. The service status appears as "stopping". After this point, folders under the Cisco Secure ACS installation directory are locked and an upgrade to the commercial version cannot be completed. Neither can the trial version be successfully uninstalled. Workaround/Solution: Reboot the server and uninstall or upgrade Cisco Secure ACS before a RADIUS request is received. To ensure that no RADIUS requests are received, consider taking the server off of the network long enough for the installation to succeed. As an alternative, you could change the IP address of the server to an address that RADIUS clients are not configured to send requests to.
CSCeb36966	large number Windows groups causes ACS GUI timeout	When there is a large number of Windows groups (this was observed with 25000), the ACS http GUI connection times out. Workaround/Solution: Force the Windows server that Cisco Secure ACS uses to retrieve the groups to cache the groups locally. Go into Active Directory Users and Groups on the computer running Cisco Secure ACS for Windows Server. If you are using Cisco Secure ACS Solution Engine, go into Active Directory Users and Groups on the computer running the Cisco Secure Remote Agent for Windows, In Active Directory, view all the groups. In Cisco Secure ACS, configure the mappings. This works because the server has cached the information.
CSCeb43948	Could not generate valid Password with password length => 9	If, in System Configuration > Local Password Management, you configure Cisco Secure ACS to require user passwords to be nine or more characters in length, Cisco Secure ACS generates "Could not generate valid Password" messages in the logs for the CSMon service. The message appears on the schedule you define for CSMon to test services. This has been verified as a problem on 3.1 and 3.2. Earlier versions were not tested, but likely have the problem. Workaround: None.
CSCeb45624	NAR does not work comma separated source address	The documentation and the short help pages in the browser indicate that you can specify multiple IP addresses separated by commas for a source IP in the IP-based NAR section. This is not true. Any attempt to actually do so will result in Cisco Secure ACS ignoring the NAR config for the telnet connections to a router. This has been verified in ACS 3.2 and ACS 3.1. Workaround: Do not use commas to separate multiple IP addresses in NARs.
CSCeb63188	database define with special chars permitted but unusable later	Symptom: ACS allows definition of a database with special characters in the name, like "Windows (test)" but on trying to actually use the database in the 'Selected Databases' column with 3.0.3 & 3.2, the error message is 'The selected DB search list is empty'. The software should not allow naming of a database when the name cannot be used. Workaround: Do not use special characters in a database name.
CSCeb82554	External User database group mapping not works with NDS	When a Cisco Secure ACS group called "Systems" was mapped to an NDS group and all other groups were set to <No Access>, users are mapped to the Cisco Secure ACS default group. This should not be happening. This behavior was see in both ACS 3.1 and 3.2. Workaround: None.
CSCec00789	Calling-Station-ID attribute description inaccurate	In the user guide for Cisco Secure ACS, RADIUS IETF attribute 31, Called-Station-ID is inaccurately documented as only being supported for ISDN and modem calls for AS5200s. This is not true. Cisco Secure ACS supports this attribute regardless of what type of AAA client sends it.
CSCec05303	VPN3000 downloadable ACL not working on upgraded ACS	If a previous version of ACS is upgraded to ACS 3.2, the Downloadable ACL feature will not work with a VPN3000 concentrator. It works fine on a new install. If the following registry key is added, it works. No values are required within the key: REGEDIT4 [HKEY_LOCAL_MACHINE\SOFTWARE\Cisco\CiscoAAAv3.2\CSRadius\ExtensionPoints\003\AssociateWithVendors\005]
CSCec18522	PIX downloadable ACLs do not allow -; no pix object groups	The Cisco Secure ACS downloadable ACL feature does not allow hyphens, "-", in ACL definitions; however, the PIX Firewall access-list command has a "object-group" keyword. You cannot configure downloadable ACLs in Cisco Secure ACS using the object-group keyword. Workaround: None at this time.
CSCec47715	Upgraded ACS 3.2 hangs when editing groups and users or replicating	CSADMIN on upgraded ACS 3.2 will hang when editing a user or group. Often there are also service hangs when replicating. Workaround: Click on Interface Configuration, then TACACS+ (Cisco IOS). Put a check in the group option for Shell (exec). Click Submit. This setting must be left enabled, even if it is not being used, or the services will hang again.
CSCec61110	authentications on secondary acs may fail after replication	Symptom: In environment where primary and secondary Cisco Secure ACS primary and secondary servers are kept in synch using the replication feature, user authentication may fail for users defined in an external database users and the Failed Attempts log will contain an "external DB not configured" error. Conditions: This happens with certain external database types such as LDAP, NDS, and the various token server types. It can't happen with the Windows external DB. By configuring external databases in a different order on the primary and secondary Cisco Secure ACS servers, authentication fails on the secondary server for users defined in the databases configured in a different order. If external databases are configured in same order on primary and secondary servers, this does not happen. For example, if you configure two instances of LDAP external user databases on primary and secondary servers but configure them in different orders, after users are replicated, LDAP authentication attempts fail on the secondary server. Workaround: For each database type involved in the problem, delete the external databases on all secondary servers and reconfigure them in the same order that they are defined on the primary server. If this fails, delete the affected external databases on the primary and secondary servers and reconfigure them.
CSCec63624	ACS 3.2 admin gui locks and displays action canceled message	If the Shell (exec) service is disabled in Interface Configuration > TACACS+ (Cisco IOS) and you attempt to access a group other than the default group, the Cisco Secure ACS HTML interface ends the administrative session. Workaround: To start a new session, close the browser window, open a new browser window, and access the HTML interface again. To permit access to groups other than the default group, enable the group-level Shell (exec) service in Interface Configuration > TACACS+ (Cisco IOS).
CSCec74892	csutil sometimes messes up SPC NARs	In Cisco Secure ACS for Windows Server 3.2, if you re-intialize the internal database by doing "csutil -q -d -n -l" or if you dump your databases using "csutild -d" and reimport by doing "csutil -l", Network Access Restrictions defined in the Shared profile Component section of the HTML interface may lose all of the permitted/denied calling point entries. Workaround/Solution: None at this time.
CSCin45582	VMS2.2-BT:Shared Profile components are not overwritten	If you re-register a Management Center application with Cisco Secure ACS, Cisco Secure ACS retains the authorization settings from the previous registration rather than replacing them with default authorization settings. Workaround/Solution: None.

Table 4 Resolved Problems in Cisco Secure ACS for Windows Server, Version 3.2
Bug ID	Summary	Explanation
CSCdu33140	PPTP Tunnel with VPN3000 and MS-CHAP V2 method	A PPTP tunnel using a Cisco VPN 3000-series concentrator and MS-CHAP version 2 is created successfully.
CSCdu35333	CSNT should not require unique NAS&port values for ip pools	You can configure Cisco Secure ACS to use the username to identify sessions rather than unique port numbers.
CSCdx81906	Unable to replicate to more than 20 partners	The limitation of 20 replication partners no longer is true. You can configure Cisco Secure ACS to replicate to more than 20 other Cisco Secure ACSes.
CSCdy14259	TACACS+ ASCII login doesn't work correctly with CRYPTOCard	We successfully tested TACACS+ ASCII login with CRYPTOCard 5.32 in challenge response (async) mode. Settings in Cisco Secure ACS should be as follows: •"From Token Server (async tokens only)" check box should be selected •"Password" box should have a string in it. Both settings are located under TACACS+ Shell Configuration on the CRYPTOCard Token Server Configuration page in the External User Database section.
CSCdz09728	RSA TACACS+ authentication failed after password changing	TACACS+ authentication using an RSA token server functions properly after password changes are applied.
CSCdz14051	wireless client cannot EAP login when max session limit is 1	Newer versions of Cisco Aironet include the RADIUS Service-Type attribute to distinguish between full login and rekey authentications. We used this change to enable Cisco Secure ACS to handle rekey authentications correctly.
CSCdz19494	Repeated LEAP auths from single client cause memory leak	We resolved the memory leak.
CSCdz27070	disc-cause attribute is wrong in Tacacs+ Acct logs	Cisco Secure ACS logs the correct value for TACACS+ idle timeout.
CSCdz87654	Authentication failure with dynamic mappings	Cisco Secure ACS correctly assigns users to the group designated in the user profile when group mapping for the user would otherwise assign the user to the No Access group.
CSCea19930	Leak in CSAuth when using IP based NARs	We resolved the memory leak.
CSCea35303	Change of NDG for NAS isn't applied until CSAuth is restarted manual	Changing NDGs for a AAA client no longer requires a restart of the CSAuth service.
CSCea40150	HTTPS Session to ACS Passes Username in Clear Text	Cisco Secure ACS establishes the SSL tunnel prior to submission of administrator name and password, preventing the administrator name from being sent in the clear.
CSCea54048	Password changing by UCP is not trigger for automatic DB replicate	Password changes made using a User-Changeable Password web page trigger database replication, when replication is correctly configured.

Opening a TAC Case

Using the online TAC Case Open Tool ( http://www.cisco.com/tac/caseopen) is the fastest way to open P3 and P4 cases. (P3 and P4 cases are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution. If your issue is not resolved using the recommended resources, your case will be assigned to a Cisco TAC engineer.

For P1 or P2 cases (P1 and P2 cases are those in which your production network is down or severely degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.

TAC Case Priority Definitions

To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.

Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
