I'm sitting here making a call to GetAccessRights for an IUser and the RoomAccessRights object i have only has false values for a room, even if I set specific rights for a usergroup in admin. Is there another way to see if a user has a particular accessright to a room than this?

public static bool IsRoomMember(this RoomBase room, StarCommunity.Core.Modules.Security.IUser user)
{
if (room == null || user == null)
{
return false;
}

RoomAccessRights rights = room.GetAccessRights(user);
if (rights == null)
return false;
return rights.ReadRoom;

}
