Is there a way to boost the performance of the ComputerInGroup UDF? Is there a way (or a better option)to not have to query AD multiple times during the logon process? The computer group membership doesn't change during the logon process, so is there a way to cache the computer's memberships?

I'd like something similar to the way the InGroup function was updated w/ kix 4.x where the group-membership cache is stored in the registry hive of the current user and contains security-identifier-to-groupname mappings.

Thanks
