I have two active directory security groups lets say Group1users and second Group2users. All the users belongs to these groups. Both of these groups are a member of another security group GroupUsers. If i map the acs group to GroupUsers, the users authentication puts the users into the default group. but if i use Group1users or Group2users into the mapping, they are placed into the right group. Is the hierarchical group supported into the acs? Any solution for this if its not supported.
