[Serusers] Authenticate to Active Directory

[Bob McCormick]

Does anyone know if there is a way to authenticate SER to MS Active
Directory?   I'd like to use an existing user database instead of
having to manage users myself, and most of our users are in Active
Directory.

Has anyone tried this?

What are most SER users using for authentication?  Is anyone here
tying into any kind of existing organization user database?
