Using version 5.6.9, sometimes while using the client, the server looses the Active Directory Settings ("Allow Active Directory logon" and "Group Names"). This has happened twice in last 2 weeks. I then need to login as a local user and enable the settings again.

Is this a known issue that is fixed in the later versions? Of if this is not known which log files do I need to send to get it fixed when it happens again?

Thanks
