The script was written by:
Deven Corzine <deven@fuse.net>
Unix System Administrator, Fuse Internet Access
It's part of a larger user management system written by:
Joshua Phillips <jphillip@ecn.purdue.edu>
Fuse Internet Access Management Trainee
We can't support the script at this time, I'm posting it because I've
already gotten several requests for it from the community. We'll be
releasing the entire package in the near future.
The script will require some minor edits for file locations in your
environments, but it's well commented. It also assumes that you have
BOTH a login password, and a Full Access password. If that's not the case,
just remove the code for the second password prompt and response from
the Perl script.
Hope you like it.
