Thank you for your reply Tom. In regards to the hostname, do you mean I
should check the ldap URL? If so what I did is use the ldp.exe on windows
and instantiated a connection to the active directory using the same url
that im using and it worked fine. For the port, basically I'm using port
389 and in both the inbound and outbound rules there is a rule that allows
communication on that port. I attached most of the errors that I'm getting,
and I would really appreciate if you could have a look and give me some
advise on what to do ?
