I have configured the Multiplexer to use ActiveDirectory provider, and I have granted access to the groups (both in web.config and EPiServer on root level). But I can't log in either in Relate or in Edit/Admin mode. In the EventLog on the Domain Controller I can see that the user I tried to log in with have successfully logged on to the domain, but relate is able to handle. If i write wrong username/password relate does give an error, but with correct credentials it says nothing.
Anybody think of anything that can help?
Can you access Community admin UI with different user and check user you are using in which *community* groups he/she is?
If we are looking at menu provider for the community module then menu item is provided if user "is Community admin".
Tracing down the path we can see that those administrative access rights are fetched by EPiServer Common module by executing
[spEPiServerCommonGetUserGroups] procedure which actually reads data from tblEPiServerCommonGroupUser table. Try to check those groups and see what's written there and how groups are synced.
