Hello.
I have a Delphi program that is trying to connect to LDAP on port 636 hosted
by Active Directory on a Windows 2003 server. I get a "Server Down" error
from the Delphi wrapper for Microsoft's winldap.h
Just a note, everything works fine when I connect using java over SSL.
Here is the event log error:
