I am reading through the requirements and I see this:

The GroupWise Mobility Service obtains users and groups from an LDAP directory or a GroupWise system.

Lightweight Directory Access Protocol (LDAP) v3

Any shipping version of NetIQ eDirectory fills this requirement. Other LDAP directories are not currently supported.

Does this mean that AD isn't supported as an LDAP source? If I read the above correctly the only supported source is eDirectory. I have GMS 2.0.0 on my test server and I have it pointed to our AD and it has worked fine. Now that I am ready to upgrade our production server I want to make sure that I get it installed using a supported source for LDAP.
