I have been tasked with cleaning up the AIX boxes. One of the things I wanted to do was add the users full names to the passwd file so that I can figure out who users are fairly easily. I did not want to do this manually, so here is a script I came up with to do it for me. It takes the passwd in the same folder as the script, and creates a passwd.new file that you can then replace the old passwd with.

#!/usr/bin/perl -w
=head1 Author: TechFly
Name: SyncUserNames.pl
Description: Add the uses names from AD into the passwd file.  The scr
+ipt will read the passwd file in the same directory, and then connect
+ to AD.  It will use the usernames in the passwd file to look up the 
+users full name in AD, then populate that in a passwd.new file.  It a
+lso creates a nousername file that is populated with the users not fo
+und in AD.
