I've set up an ADMT server and have done the following:
1. Set up trust between source and target.
2. set up auditing on both source and target
3. Disabled sid history filtering.
I have migrated groups from the source to the target and ensured I selected the 'migrate SID'...option also.
When I migrate a user from the source, it goes to the target. However, it doesn't have any of the groups associated to it on the source in the target. I've attached the ADMT log file also.
Thanks for helping
