NOTE
Be sure to check the domain search suffix.
For a domain such as ad.example.com, the search suffix should be dc=ad,dc=example,dc=com, but sometimes it will only show as dc=example,dc=com. This will prevent Active Directory authentication from working. Insure that it is correct for your domain name.
