default — system default database file for a trusted system
The system default database is unique in that it defines system-wide
global parameters for a trusted system.
It is designed to provide values for users and devices on a global
scale rather than requiring an administrator to replicate values in user or
device databases when they are all the same. In addition to being easier to
specify global values, it is also much easier to make a global system change
The system default database is made up of four types of values:
- system-wide parameters
These are parameters
that do not have corresponding specifications in
any other trusted system database.
If a system-wide parameter is not specified in the
default database, then it is undefined.
- user parameters
These parameters are typically specified in a protected password database file.
- terminal control parameters
These parameters are typically specified in the terminal control database file.
- device assignment parameters
These parameters are typically specified in the device assignment database file.
System default parameters may be specified for fields found in the protected
password, terminal control, and device assignment databases. When a specific
entry is retrieved from one of these databases, a structure called,
that contains all
of the explicitly specified values, is provided to the caller.
A second structure, called
is also provided which defines those values supplied from the system
database. Each of these structures has a corresponding flag structure called
respectively, that indicates which fields in each
structure have been specified and are valid for use.
Programs honor the user or device specific value first if one is provided.
Otherwise, the program may choose to use the system default value if one has
been specified. If neither value is specified, the program may supply a
reasonable default value or abort.
For descriptions of the specific fields provided by the protected password,
terminal control, and device assignment databases, see the corresponding
manual pages listed in
section for those databases. The following fields are unique to the system
default database and can not be specified in any of the other system databases.
This name is set to the string "default".
This flag field indicates whether or not boot authentication is required to
boot the machine.
If authentication is required, it is performed by the system
program prior to completing system boot.
