LDAP on Windows server

Hi Experts,

I am trying to locate my ldap server on Windows network.  The server was setup by a consultant.  I know the port 389 has been open on firewall to one of our Windows domain controller (W2012r2).  But when I login the DC, I could not find any ldap service on the DC.  So I don't know what consultant setup on the server for ldap.   How can we find out our ldap or what the consultant installed on the DC to have it functioning as ldap?

Thank you very much for your help in advance.

Your domain controller IS your ldap server.
Which is to say the ADDS will answer on port 389 (and also on another port for SSL, though I dont recall which) for LDAP queries.

Eric is correct, the DC is your LDAP server.

On a related note you will want to install HOTFIX http://support.microsoft.com/kb/2862304

This is a fix for all 2008/2012 DCs and will prevent slow responses to deeply nested LDAP queries.

It's a preventative measure that can save you headaches in the future.

Thank you very much for all of response.  We did have slow authentication process.  I think we will apply the hotfix.  

By the way, I try to telnet to the DC on port 389, but didn't get response.  I am wondering if the port is open?  Please advise.

Thank you again.
