3269 is the SSL port for a global catalog only.

389 is the standard LDAP port.
3268 is the standard Global Catalog port.

As in my previous post,  I would try 389.  If the server is a global catalog,  you can also do 3268.  Those are only available if the server is a GC though.

3268 works just fine however we need to make 3269 work and for some reason it doesnt. I neve set anything up to make it work on the previous server other than make it a GC. Any other suggestions?
