Best working for me 2 physical hosts PDC/Openldap  BDC/Openldap Ldap
Master-Master Replication. So PDC is down BDC
will serv authentication and shares This is done with : Ucarp servs a unique
IP for the domain only the master holds the ip. When the master is down the
bdc gets the ip.
The shares run on a glusterfs brick 
and are replicated in real time from PDC to BDC.
For Wins samba4wins (http://www.enterprisesamba.org/samba4wins/) running two
wins server one on PDC the other on BDC
Push and Pull. Both set in the network config of the windows clients.

Betreff: [Samba] Samba DC Backup Best Practices

I recently suffered the misfortune of a corrupted winbindd_idmap.tdb file on
my Samba PDC. Since we run several other Samba servers (file, print, proxy,
etc.) as well as around 50 Win32 clients, the recovery and clean up was a
pain. I'm glad we do not have 1000 clients...

To this point I was not running a BDC. I realize now that this was probably
a bad thing. However, in addition to adding a BDC, are there any "best
practices" for backing up critical Samba files in an effort to make recovery
"easier?" I have read a multiplicity of opinions offered to me by the oracle
at Google, but am wondering if the Samba community has some established best

It was sort of nightmarish having 50+ users sitting around waiting for their
network to be fixed, and I'd rather not go that way again so feel free to
tell me how stupid it was to not have addressed this before. ;-)

Samba: 3.6.6
Ubuntu: 10.4.4 LTS
