Hi,
Recently we changed our samba server to a bigger and more powerful
system ( centos 5.2 )
The config file and smbpasswd and other passwd and group files were
copied to the new server and it then assumed the same identity as the
old one in the dns and ip address.
It seems to have gone very well except we now seem to have a problem.
There are windows XP workstations that were domain joined to the old
server
and now connect well to the new one.
But if you try to login on one of these workstations with an ID that
was not logged onto it previously it does not authenticate.
The solution is to unjoin and then rejoin the workstation but there
are a lot of them and we don't want to do that.
Also it seems that this situation has arisen just recently and was
working before on the new server and so I am wondering what could
have happened earlier this week.
That info is held in the *.tdb files. Centos stores them in
/var/cache/samba/. If the old & new server are both Centos, just copy
them over from the old box. Stop samba first, make a backup copy -
just in case, restart samba. The machines that you've rejoined to the
new box will need to be rejoined again, but all others should be ok.
The SID-to-UID mappings are in the tdb files too - it would probably
be best to have all PCs reboot after the update - rejoin as needed.
If the distros are different I think the tdb files are compatible, but
I'm not sure.
On a related note... if you store your information via ldap (Samba sids
and such)... is it true you need not bother backing up or moving any of
the .tdb files?
