We have added a active directory group as a user to the database. Surprisingly, some of the member of an AD group and can't connect to the database and get error

"Cannot find OLAP cube xxx. either the OLAP database has been changed or you dont have permissions to connect to cube"


But when the Users are manually added to the database, they user can access the server.

We thought It was probably some Kerberos/AD issue. But the Kerberos logs did not show any issue.

We also tried removing and re-adding the AD group to the role, just in case...


Can someone please advice abt the reason why this will happen.
