Thank you for answer. The problem I have is "user1" need "su" privilege. If I grant "su" privilege, it can "su" to anyone. What I want is user1 can ONLY "su" to user2.
my /etc/sudoers setup:
# User privilege specification root ALL=(ALL) ALL user1 ALL=(root) /bin/su
any ideal to fix it?

I know this is big security risk but .... Anyone
know how to do it?
Thanks.
Check out the sudo command. You can alter the /etc/sudoers file to specify that the "source" user can only run a command as a specified "runas" user. The syntax would look something like:
sourceuser ALL = ( runasuser ) command
Let's say you wanted the user "bob" to be able to run the "grep" command as user "fred". The following line could be added to the /etc/sudoers file:
bob ALL = ( fred ) /bin/grep
"bob" would use the sudo command to execute the grep command:
sudo -u fred /bin/grep 'stuff' logfile
This is a simplistic example, check the man pages for "sudo" and "sudoers" for more information. -- Jay Leafey - jay.leafey@mindless.com Memphis, TN
