Problem Symptom
Recently I need to add a new AD group to the firewall FSSO setup to be used in a policy. The new AD group is not showing.
Solution: Execute the FSSO Force Sync command
The common fix for this is to create a filter on your FSSO agent server, that will ONLY look for the groups you specify.
However, the newly added AD group still does not show up after applying the filter.
The solution to this problem is to execute the FSSO Force Sync command:
execute fsso refresh
The AD group shows up after the FSSO refresh.
