Hi Rowland,
I've decided to roll back samba on DC1 to the state from a couple of
weeks ago, before I started all this mess...
Since the email subject change :)
Stopped bind9 and sernet-samba-ad and copied /var/lib/samba aside.
Restored samba folder from backup, started sernet-samba-ad but bind9
fails to start:
Jul 22 14:39:39 dc1 named[27846]: generating session key for dynamic DNS
Jul 22 14:39:39 dc1 named[27846]: sizing zone task pool based on 5 zones

Jul 22 14:39:39 dc1 named[27846]: samba_dlz: Failed to connect to

Jul 22 14:39:39 dc1 named[27846]: dlz_dlopen of 'AD DNS Zone' failed
Jul 22 14:39:39 dc1 named[27846]: SDLZ driver failed to load.

Jul 22 14:39:39 dc1 named[27846]: loading configuration: failure
Jul 22 14:39:39 dc1 named[27846]: exiting (due to fatal error)
Initially I thought permissions / ownership issues but the current and
the backup copy looks identical:
dc1:/# getfacl var/lib/samba/private/dns/sam.ldb
# file: var/lib/samba/private/dns/sam.ldb
# owner: root
# group: bind
user::rw-
group::rw-
other::---
dc1:/# getfacl var/tmp/bacula-restores/var/lib/samba/private/dns/sam.ldb
# file: var/tmp/bacula-restores/var/lib/samba/private/dns/sam.ldb
# owner: root
# group: bind
user::rw-
group::rw-
other::---
Files have the same size and time stamps, both last modified in 2013.
Also no difference in ownership and permissions for the parent
samba/private/dns folders.
After rolling back /var/lib/samba and restarting services DNS and AD are
working again.
Any ideas?
Thanks,
Adam
