Updating documentation (WOW!) and ran across question: how often does DSS check Active Directory for user and rights info? Does it read on boot, or on each access? If I delete a user in AD, does DSS re-read, or do I need to refresh in DSS or even delete the user again in DSS?
Synchronization is done every 15 minutes, so you need wait a while.
If users still do not appear please clean your browser cache and re-login to WEB GUI. We do this so that there is not added traffic.
