JSI Tip 6361. LDP.exe won't access a domain controller by IP address on port 636?

When you attempt to access the Active Directory with an IP address from LDP.EXE using SSL (LDAP over port 636), you get an error because authentication has failed.

The client system compares the Subject and Subject Alternative Name fields of the certificate with the name specified for the connection and they don't match because you used an IP address.

To workaround this feature, you must use the host name or FQDN.
