ALTER USER Command
Considerations
•
Changing your logon password
Only the owner of a user’s authentication record or the owner’s group manager 
can use the ALTER USER command to change a user’s password. However, with 
the Guardian PASSWORD program, any users can change their own password. In 
addition, users can change their own passwords during logon. 
For example, this command changes the user’s logon password to itsme:
4> PASSWORD itsme
When you change your logon password, your Safeguard authentication record is 
automatically updated.
Your password is subject to restrictions defined by the configuration attributes 
described in Section 16, Safeguard Subsystem Commands.
•
Adding or deleting default protection while a user is logged on
If you add or delete default protection for a user while that user is logged on, and 
the user subsequently creates a disk file during that session, the FUP INFO and 
TACL FILEINFO displays are not updated until the next time the disk file’s 
protection record is altered.
•
Changing Guardian default security while a user is logged on
If you change the Guardian default disk file security for a user while that user is 
logged on, the change does not take effect until the next time the user logs on or 
issues a Guardian VOLUME command.
•
Changing a user’s primary group
Programmatic logon sets the group list of a process to contain the user’s entire 
group list and also copies the user’s primary group to the real group ID, effective 
group ID, and saved set-group-ID of the process. Because a user’s primary group 
can differ from that user’s administrative group, the effective group ID of a process 
can differ from the administrative group of the process as defined by the PAID. 
Examples
1. The PRS group manager owns the authentication record for PRS.DARLENE. The 
manager enters the following command to transfer primary ownership of that 
record to the user who has user ID 86,2 and to require that Darlene change her 
logon password every 35 days:
=ALTER USER prs.darlene, OWNER admin.sue, &
=PASSWORD-MUST-CHANGE EVERY 35 DAYS
Because the OWNER attribute for PRS.DARLENE was changed to a member of 
another group, PRS.MANAGER can no longer manage this authentication record.
