Hi Guys,
Thanks for the replies and advice.

I thought about chroot, I may try that. As they so often are, the requirements for this task are very nebulous, but I get a sense that part of what I am doing is protecting DBA's from each other, so moving them all into the same chroot'ed envionment may not be a good idea.

The environment is AIX, and I understand that AIX has something alot like Solaris Zones, called logical partions or LPARs. Maybe I should look at that, if they are like Zones then I can give everybody read-only access to one set of executables w/o using any more storage.

I too am interested in specifically why replacing the user's login shell is a bad idea, beyond the obvious objections like I could write a crappy script, etc.
