Comment: Supporting multiple communities?

Bernard:I am trialling yacs for small communities around my organisation, so it is an intranet solution of sorts. An example of membership groups would be those people who have attended our management development training course or another for the sports society. Content would not be common, but users would be. Ideally I could change user authentication to use our Active Directory.

p.s. I'm having a problem with user authentication. Replying to the confirmation email for a new user id gets a reponse that registration is successful, but the user login gets rejected.
