[Samba] Samba 4 + Zimbra 8

[Mārtiņš Gailītis]

Hi, Denis!

Thnx for your reply!

I'm using ldap auth.
Anyway - found the problem. There was SplitDNS configured and time after time Zimbra internal DNS could not find ldap by it's DNS name :)
Removed that stupid SplitDNS config, changed resolv.conf and i guess topic could be closed. ;)

regards,
Martins
