It seems that you forgot the transfer the Machine and Domain SID to
the new configuration. The domain logon does not work correctly
if the Server SID is not the one that is cached in the clients registry
during domain join.
There are several possibilities:
* use smbpasswd to get the SIDs from a running Domain controller,
see the documentation of smbpasswd, the options where added
in 2.2.8 (or 2.2.7). Although this is the recommended method it did not
work for me, I could transfer the Domain SID with smbpasswd but
somehow the Machine-SID seems to be importat to but did not
* get the SID from the file MACHINE.SID (only available in older
Samba versions, I think your 2.2.3a used this file) on your old server,
transfer the SID to the new server and import the SID using smbpasswd.
* since you used an "old" Samba the SID should be in the file MACHINE.SID,
copy this file to your new box in the directory where secrets.tbd
is located, stop Samba, move the file secrets.tdb away (backup),
restart Samba. On startup Samba can not find secrets.tbd which
you moved away and should look for the file MACHINE.SID,
import its contents (the SID) into a newly created secrets.tdb and
delete MACHINE.SID (I'm not shure but you can grep the
Samba source code for MACHINE.SID and see how this is
* The method that worked me, since I already had a secrets.tdb
on the old server:
- copy the file secrets.tdb on your new server to another directory
- stop Samba
- replace the file secrets.tdb on your new machine with the
file secrets.tdb from your old server (the SIDs are in this file)
- start Samba
Another reason for your problem might be that the the startup scripts
are not accessable for the user that logs in.
Hope this helps, good luck
