[Samba] Moving a Samba PDC from Solaris 2.8 to CentOS 4.4

[Ralf Aumüller]

Hello,

I try to move a Samba-PDC (3.0.24) from Solaris 2.8 to CentOS 4.4 with the
guidance from:
http://www.samba.org/samba/docs/man/Samba-Guide/upgrades.html#id333969
(Replacing a Domain Controller)

At the moment I am trying this in a test environment. This means the
following (not the real names/IPs. Just for illustration ;-)):

smb.conf entries:
...
netbios name = smbtest
interfaces = 1.1.1.1/255.255.255.0
...

Hostname Solaris: solaris
Virtual network interface with ip: 1.1.1.1

Hostname CentOS: smbtest
Real network interface with ip: 1.1.1.1

Than I followed the docs expect that I don't power off the Solaris machine.
I just stop the samba daemons and delete the virtual network interface.

When I did that, the Windows XP clients can't login in the Domain anymore.

After some investigation I found out that the SIDs of the domain and of
the Linux-host are not the same than before on the Solaris host.

When I change the SIDs with "net setlocalsid" and "net setdomainsid" to the
original ones it seems to work again.

Any ideas why that happens? Is this the expected behavior (because of the
hostname change)?
Do I have something else to change to test the PDC move?

Best regards,

Ralf
