Hi,
Thankyou for looking at this for me the module was Net::Ldap I have just found the documentation answering my question.
My problem was that when I started this morning I thought that I wes dealing with a simple hash, but what I am actually dealing with is a container with its own stucture :-(
So what I really need to do is get my head around moving around and modifying the attributes inside it. I will post some code when I figure it out :-)
