These package allows you to access Kerberos V administration servers. You can create, modify, and delete Kerberos V principals and policies.
More information about Kerberos can be found at » http://web.mit.edu/kerberos/www/.
Documentation for Kerberos and KADM5 can be found at » http://web.mit.edu/kerberos/www/krb5-1.2/krb5-1.2.8/doc/admin_toc.html.
This extension defines a KADM5 handle returned by kadm5_init_with_password().
The constants below are defined by this extension, and will only be available when the extension has either been compiled into PHP or dynamically loaded at runtime.
The functions kadm5_create_principal(), kadm5_modify_principal(), and kadm5_modify_principal() allow to specify special attributes using a bitfield. The symbols are defined below:
| constant |
|---|
| KRB5_KDB_DISALLOW_POSTDATED |
| KRB5_KDB_DISALLOW_FORWARDABLE |
| KRB5_KDB_DISALLOW_TGT_BASED |
| KRB5_KDB_DISALLOW_RENEWABLE |
| KRB5_KDB_DISALLOW_PROXIABLE |
| KRB5_KDB_DISALLOW_DUP_SKEY |
| KRB5_KDB_DISALLOW_ALL_TIX |
| KRB5_KDB_REQUIRES_PRE_AUTH |
| KRB5_KDB_REQUIRES_HW_AUTH |
| KRB5_KDB_REQUIRES_PWCHANGE |
| KRB5_KDB_DISALLOW_SVR |
| KRB5_KDB_PWCHANGE_SERVER |
| KRB5_KDB_SUPPORT_DESMD5 |
| KRB5_KDB_NEW_PRINC |
The functions kadm5_create_principal(), kadm5_modify_principal(), and kadm5_get_principal() allow to specify or return principal's options as an associative array. The keys for the associative array are defined as string constants below:
| constant | funcdef | description |
|---|---|---|
| KADM5_PRINCIPAL | long | The expire time of the princial as a Kerberos timestamp. |
| KADM5_PRINC_EXPIRE_TIME | long | The expire time of the princial as a Kerberos timestamp. |
| KADM5_LAST_PW_CHANGE | long | The time this principal's password was last changed. |
| KADM5_PW_EXPIRATION | long | The expire time of the principal's current password, as a Kerberos timestamp. |
| KADM5_MAX_LIFE | long | The maximum lifetime of any Kerberos ticket issued to this principal. |
| KADM5_MAX_RLIFE | long | The maximum renewable lifetime of any Kerberos ticket issued to or for this principal. |
| KADM5_MOD_NAME | string | The name of the Kerberos principal that most recently modified this principal. |
| KADM5_MOD_TIME | long | The time this principal was last modified, as a Kerberos timestamp. |
| KADM5_KVNO | long | The version of the principal's current key. |
| KADM5_POLICY | string | The name of the policy controlling this principal. |
| KADM5_CLEARPOLICY | long | Standard procedure is to assign the 'default' policy to new principals. KADM5_CLEARPOLICY suppresses this behaviour. |
| KADM5_LAST_SUCCESS | long | The KDC time of the last successfull AS_REQ. |
| KADM5_LAST_FAILED | long | The KDC time of the last failed AS_REQ. |
| KADM5_FAIL_AUTH_COUNT | long | The number of consecutive failed AS_REQs. |
| KADM5_RANDKEY | long | Generates a random password for the principal. The parameter password will be ignored. |
| KADM5_ATTRIBUTES | long | A bitfield of attributes for use by the KDC. |
This simple example shows how to connect, query, print resulting principals and disconnect from a KADM5 database.
