I was running 3.8.2 and upgraded to 3.9.3 last night. It seemed to have been successful until this morning. Some users' rosters were missing groups. I verified the group sharing was set up correctly. I removed the group share & reconfigured it but it still would not show up. It did not show up on the user roster from the web admin page or their Spark client.
I reverted to a snapshot taken before any upgrades were done so the system is up & running like normal again. I will be attempting the ugprade again this weekend and hoping someone else may have a solution for this problem.
I am using Active Directory for users, groups, and authentication. Running OpenFire on CentOS 5.9 (32-bit)
