Access Manager Userclasses connecting to Active directory

[Gadgety]

I've always used SUN ONE LDAP for the authentication in Cognos, it was simple and straight forward:

In Access Manager

Enter users domain/username token
Set their Userclass access to restrict what they could see.

That was all we had to do!

I have to set up the same but now pointing to MS Active directory.

What do I need to know/do, the documentation doesn't seem be very clear.

Many Thanks

Jason
