I've been trying to move a samba PDC (Samba 3.02 on SUSE Linux 10) to
a new machine.
Since this is a small network (less than 15 workstations and a
comparable number of users) I'm using the tdbsam backend, and
therefore can't (I believe) set up a self-replicating BDC. So the
purpose of this effort is to develop a backup plan that I know will
work when the server goes down and I can't immediately figure out what
the problem is. I'd like to have on hand a backup of the files
necessary to set up a new server on a different machine to get back in
business.
As far as I can tell, this should work by setting up a seperate linux
machine with the samba server installed & running, configuring the
network connection using the same hostname, and then importing a
certain set of files from the original server.
The files I've copied over are:
/etc/passwd
/etc/group
/etc/shadow
/etc/security/fileshare.conf
all of /etc/samba/*
all of /var/lib/samba/* including subdirectories /profiles, /
netlogon, /drivers, and /printers.
In order to keep the same permissions and ownership info, I've
transferred these files using tar -cpf ...
I'm close to having this work just right, but not close enough.
When I switch a client from the original server to the backup server,
and try to log on, I get an error telling me either that my account
has expired, or that my account expires today and I must change my
password. Using pdbedit -Lv on the new server I find that the Password
must change date is 1969. But using pdbedit to change the date to some
time in the future doesn't fix the problem. If I remove and replace
the account using smbpasswd -x and then -a, I can then log on without
the error.
But it's cumbersome and time-consuming to manually remove and replace
all of the accounts, and more importantly, it's not answering the
question of what's causing the problem.
I assume there are more files that need to be brought over, but I
don't know what they are.
Thanks for any assistance.
Here's the smb.conf:
# smb.conf is the main Samba configuration file. You find a full
commented
# version at /usr/share/doc/packages/samba/examples/smb.conf.SUSE if
the
# samba-doc package is installed.
