Time synchronization with Active Directory did not working properly
Sometimes you can see that the Time of your Artica server is not correctly synchronized
Usually the synchronization process (using NTP protocol) is executed each 2 hours but when using Kerberos method, the synchronization is not performed and Artica server can loose time between the Active Directory.
This behaviour is correct when using NTLM method.
