Managing Users and Security
Deleting Users From the System
When you delete users from a system, either because they start to work on a different
system or because they have left the company, you should first delete their accounts and
then clean up their files and subvolumes:
Task 1: Delete the User Account
Use the TACL DELUSER program to delete the user's account from the system. The
Super ID (255, 255) can delete any user from any group in the system, but group
managers (n,255) can add users to and delete users from only their own groups.
Note. If your system is protected by the Safeguard security product, the DELUSER program
might not be available for system operators to use.
1. Log on as the Super ID (255, 255) or a group manager (n,255).
2. At your TACL prompt, enter:
> DELUSER group-name.user-name
where group-name and user-name are the group and individual names,
respectively, of the user who is to be deleted. Each name can contain from one to
eight letters or digits, and the first character must be a letter.
You can include options of the TACL RUN command in the DELUSER program
syntax. See the TACL Reference Manual for details on using the RUN command.
Example
In this example, the group manager of the SALES group or a super-group user (255,n)
can delete the user SALES.BONNIE and other members of that group.
To delete the user SALES.BONNIE, enter:
> DELUSER SALES.BONNIE
This message is displayed:
SALES.BONNIE (8,1) HAS BEEN DELETED FROM THE USERID FILE.
Task 2: Clean Up the User's Disk Space
Because old or unneeded files use disk space and can constitute a security problem, you
should delete or move the files and subvolumes owned by a deleted user. Encourage
users to purge or move their subvolumes and files before you delete them from the
system. If they cannot perform this task, their managers might ask you to help clean up
the subvolumes and files:
1. Run a Disk Space Analysis Program (DSAP) report on each user's subvolumes on a
specified disk volume:
> DSAP $disk, BYSUBVOL USER group-number,user-number
