Me, too. I like it a lot. It's very clean, and well thought out.

One thing to mention here is that Net::SSLeay does not allow more than 
one concurrent LDAPS handle. Most people don't need that, but worth 
noting anyway...

My reasons for using Net::LDAP are that it is ubiquitous, well tested, 
and well maintained. Another reason is that it's platform independent, 
which can be a real lifesaver if you need to deliver the same code to 
e.g. win32, linux, and unix machines.

I have probably written more than 100k lines of code with Net::LDAP, and 
I recommend that if you are just getting started using perl with LDAP 
that you start to do the same :-) Net::LDAP is drop-dead easy to code to 
and drop-dead easy to subclass, which makes for very rapid development.

When I design a piece of LDAP functionality which needs to be really 
fast I just write it in C to begin with. I don't see much sense in using 
a perl wrapper around C libraries.
