[Samba] SAMBA 3.6.6 PDC domain not available / no challenge sent to client
Dear all,
I am new to this list so please excuse me if my posting should not
correspond 100% to the rules. Furthermore, even if I use SAMBA since
many years, I have only a very basic knowledge of this software.
I am experiencing a problem with my SAMBA primary domain controller that
I have migrated from an openSUSE server to LinuxMint Debian Edition
201303 a week ago. I am able to join a new PC to the domain (up to now,
I have only tried one with Windows XP) but when I want to log on, I get
a message like: The system could not log you on because the domain XXX
is not available (it is a german message and says "domain" and not
"domain controller"). Google has found a lot of postings concerning
this
problem but they concern mainly LDAP backends and none of the proposed
solutions worked for me. Most liekly I have done something absolutely
silly...
What I have done so far:
I have set up the SAMBA server, version is 3.6.6 with tdb backend. I
have copied the smb.conf, passdb.tdb and secrets.tdb from the old
installation. Perhaps this was wrong, but in the past this has worked. I
wanted to avoid changes of the SIDs of the domain and the users/groups
so that I did not need to reinstall my PCs...
For the PCs that are already in the domain everything seems ok, even if
there are error messages in the log files for the PCs running Windows 7,
but that was already the case on the old server (e.g. [2013/04/27
14:16:04.751908, 0]
rpc_server/netlogon/srv_netlog_nt.c:976(_netr_ServerAuthenticate3)
_netr_ServerAuthenticate3: netlogon_creds_server_check failed.
Rejecting auth request from client XXXXX machine account XXXXX$)
The new PC can join the domain and it seems to be in the domain because
I can see it with pdbedit:
# pdbedit -L -v -u vm1$

It also has a corresponding UNIX account:
#grep -i vm1 /etc/passwd
vm1$:x:1201:1201::/nonexistent:/bin/false
When I try to log on to the domain or to access a public share on the
server which is not possible either, I get the following message in the
log file of the PC:
[2013/04/29 20:02:42.089737, 0]
rpc_server/netlogon/srv_netlog_nt.c:931(_netr_ServerAuthenticate3)
_netr_ServerAuthenticate: no challenge sent to client VM1
I do not use winbind. Every user has a corresponding UNIX account.
My smb.conf looks like this:
# Samba config file created using SWAT
# from UNKNOWN (192.168.1.11)
# Date: 2013/04/24 21:37:53

Perhaps somebody here can give me a hint where to look? I did not want
to include a logfile with debug level 10 enabled in my first posting ;-)
Any help is greatly appreciated but please don't forget that as far as
SAMBA is concerned, I am a beginner...
Kind regards,
Ralf
