Basically we have to allow users on to our frontends - and there are quite a few - but they trickle in - sometimes one a day, sometime 15.
This task could be handled by our 2nd level as well - we do not want to have to edit the password file - just incase.
Passwdfile.pm is a nice way to drop in a user and back it up. They just enter the Unix ID and path - and off they go.
I am wrestling with passwdfile.pm - I have to make sure i have decent validation.
