we did a update from 11.2.3 to 11.3.1 a few weeks ago. All works fine but there is one problem. A lot of users are not logged in to the ZAA. If i try to start a remote session with the username i get the message the user is not logged in to any device.
If i connect me to the device and look at the ZAA the user is not logged in and i can not log in because i get the error message that the username or password is wrong.

The solution is to go to the registry -> HKEY_LOCAL_MACHINE\SOFTWARE\Novell\ZCM\ZenLgn\Hist ory\Cache\domain.local and i have to delete the user.
After that the login works fine
Sometimes i have to delete the user in this registry key too -> HKEY_LOCAL_MACHINE\SOFTWARE\Novell\ZCM\ZenLgn\Hist ory\CachedUserZenNames

Is that a known bug? What can i do to solve that problem?
