Hello and Welcome!
Over the course of my time as an Admin I've done a lot of Google searches and writeen a lot of code that has been very helpful to me in my work. I will be posting things here that hopefully will help you in your quest to master some of these technologies (Or simply stand on the shoulders of midgets).
I by no means consider myself a Perl or LDAP expert. It has been a "Learn as you go" ordeal. No formal training, just get things done on an as-needed basis.
I assume that you have a basic knowledge of PERL and LDAP.
