Freezing a User's Ability to Access the System
For example, assume that the current time is 10:14 on July 29, 2005. To add the new
user ADMIN.ALICE with an expired password and a password expiry grace period of
five days, ADMIN.MANAGER enters this command:
=ADD USER admin.alice, 1,6, LIKE admin.bob, PASSWORD abc,&
=PASSWORD-EXPIRES 29 jul 2005, 10:00,&
=PASSWORD-EXPIRY-GRACE 5 DAYS
The PASSWORD-EXPIRES attribute specifies a time that has already passed.
Therefore the user’s password is expired.
ADMIN.MANAGER then displays the user record to verify the results of the command:
INFO USER admin.alice, GENERAL
The display shows that Alice has five days in which to log on and change her
password.
The PASSWORD-EXPIRES attribute can also be set to a future date. However, this
date is altered if you subsequently set the user’s PASSWORD-MUST-CHANGE
attribute or if the user changes the password before expiration.
Freezing a User's Ability to Access the System
Security administrators occasionally need to suspend a user's ability to log on to the
system. For example, when a user goes on vacation, a security administrator might
want to ensure that nobody else uses that user's identity to gain access to the system
while the user is away. A security administrator can use the FREEZE USER command
to freeze a user ID and its associated user name. While a user ID is frozen, nobody
can use the user ID or its associated user name to gain access to the system.
However, freezing a user authentication record has no effect on user aliases
associated with the user ID. The user can still log on using an alias.
