[Samba] PDC + LDAP + W2K-SP4 Domain logon

Dear all,


___Setup: 
- several wINDOWS 2000 workstations on SP4 (reg-patches applied, they 
worked on 2.x-stable)
- Samba PDC (CVS 3.0.0rc2) (machine accounts added aswell as users in 
unix & samba)
- OpenLDAP (2.1.12) <-- (Not really relevant since I tried without ldap 
too, so no info about that from this point)
- Linux <HOSTNAME> 2.4.19 #1 Fri Jun 13 15:22:09 UTC 2003 i686 unknown 
(debian)

(- also tried Samba PDC (2.x.stable))
_________

___My Problem:
Since attempting to upgrade to Samba 3.0 clients are unable to logon to 
my samba-domain.
______________


___Scenario:
at server side(linux samba PDC):

- 'testparm' command succeeds.
- Samba PDC started with all systems up and running (smbd/nmbd/winbindd)
- Tests through 'net join' command succeeds.
- Test through 'smbclient -L <my samba PDC>' succeeds aswell.
*- Test through 'smbclient -L <a windows 200 machine>'
FAILS<partial>!
Result:

	session request to *SMBSERVER failed (Called name not present)
	NetBIOS over TCP disabled -- no workgroup available
</snip>
	*quite strange error since it returns the shares?!

---> going on anyway --->

at client side(w2k):

- login on client with local administrator-account.
- browsing network IFS results in seeing only 
  the windows-2000 machines in the network and NOT the samba PDC.
- if I attempt to connect to '\\<my samba pdc>' I do get a request
  for my login and password. Login works and I can browse shares.
- I use 'net use * /d /yes' to be able to join the domain with a 
clean-sheet.
- if I attempt to join the domain IFS I get the following error:
<snip>
	The following error ocurred validating the name "IFS".
	This condition may be caused by a DNS lookup problem.

  went to the link and followed instruction in how far possible with 
Samba 
  and saw something about the _ldap._tcp.dc_msdcs record.
  added that (_tcp._ldap.dc._msdcs.ifs. SRV 0 0 0 .) to my config, but 
still no succes 
  (thought that wouldn't do much anyway, since the link says it's only 
to reduce unneccessary traffic). 
  Samba show's _only changes in nmbd-logfile_:

- Now for the suprise...
  - I was at home and still wanting to try to get this up and running 
    last weekend, so I logged on into our VPN from a Windows 2000 
(Service Pack 2!!) machine
    and attempted to logon to our domain. And suprise... it worked. 
    So i try it again now (monday), at my work, and I get the 
   "The specified domain either does not exist or could not be 
contacted."-error again.
____________

___Conclusion:
- somewhere from Service Pack 3 (I believe but not sure since I upgraded 
directly from 2 to 4) 
  and on, Windows starts looking for an Active Directory when login on 
to a domain.
  I don't know what it does afterwards, but it won't talk to my Samba 
PDC.
  I've been looking around for the past few days and I could not find 
ANYTHING with a solution.

I also tried to install the older version again 
(samba 2.x.stable (standard debian-package) without LDAP and with 
smbpasswd file), 
but no luck...

I am completely out of ideas and believe I tried everything possible....
Hope someone can explain me this mystical behaviour all of a sudden...

Kind Regards,

[Samba] PDC + LDAP + W2K-SP4 Domain logon

This may be a long shot, but does your work environment use a WINS server?

I found out recently that mine does, and by changing WINS support = yes
to WINS server = 'ip address', i got the domain thing to work. I kept
getting the same error you did.

Cheers

[Samba] RE: PDC + LDAP + W2K-SP4 Domain logon

This is strange that it worked for you, because testparm tells me that
if you use "wins support = yes" && "wins server =
<wins server IP>" at
the same time, then smbd would not start. Anyway, I tried and it doesn't 
work...


Anybody else??

server?>

Yeah, but that is not the situation, because my Samba PDC _is my 
WINS-server.

Thanks for your reply, but I am _SURE_ that it's nothing to do with my 
configuration, but with the Windows-2000 SP3.

Since this Services Pack, Windows 2000 looks for an active directory.
Again, I tried from 2 machines now with Windows 2000 SP2 and everything 
works just fine. As soon as I apply Service Pack 3, the error:

<snip>
	The following error ocurred validating the name "IFS".
	This condition may be caused by a DNS lookup problem. 
	For information about troubleshooting common DNS lookup problems,
	please see the following Microsoft web site:
	http://go.microsoft.com/fwlink/?LinkId=5171

	The specified domain either does not exist or could not be 
contacted.
						[ OK ]
</snip>

And I get the queries for _tcp._ldap.dc._msdcs.IFS. on bind log.

So clearly Microsoft is pushing their "Active Directory" on the 
market...
(Good marketing skills those guys, really Microsoft style)

The only way I know how to solve it now is to reinstall all my 
workstations with a clean win2k install and stop upgrading till service 
pack 2, but ofcourse I do not really prefer this...

I'm not so sure. Don't blame M$ too soon. Your use of
LDAP or how you use it may be the problem.

I'm not sure it does, probably not. Do other posters
complain about PDC+LDAP+W2K-SP3-4? You can't be the 
1st one with the problem. I don't use LDAP. SPs never 
affected my clients, 2, 3, 4.

Better analyze the login transactions for both SPs 
in a higher level log to be a bit more sure what is
going on.

[Samba] RE: PDC + LDAP + W2K-SP4 Domain logon

Thanks for you reply dkrnic...

Anyway... I found the problem. (but NO SOLUTION!!)

Just to summarize...
I had a win2k sp2 machine at home and win2k sp4 machines
on my work. I was unable to login my samba-pdc (v3 rc2) with
the workstations @ work, but I was able to connect from my win2k sp2 
machine at home through a VPN connection.

I now took that machine (w2k sp2 -machine from home) to my office to
test if it would also work on the network instead of a vpn connection.
and... it didn't, it gave the same error as the other machines.

In tcpdump I saw the DNS query from _ldap._tcp.dc._msdcs.<MYDOMAIN>.
This annoyed me, because my workstation from home on VPN didn't do this.

Then I came up with the plan to disable my DNS-server in my 
network-settings on my w2k-machines. Then I tried to log on to the 
domain and.... voila... it worked. When I enable the DNS-server again in 
my configuration I can't login to the domain anymore. 

I read some things about Native and Mixed -mode w2k's. I believe this is 
the whole problem. W2k's are in Native mode looking for Active Directory 
and Samba obviously... not... since it can't.

Anybody knows how I can change this behaviour of w2k towards my PDC?

Thanks!

Bjorn

You are getting closer. Let's verify your server's
and clients' TCP/IP configuration. My server is also 
primary DNS and WINS server for my clients. That 
means "wins support=Yes" and there is a named running
on the server and its IP address is topmost under both 
DNS and WINS tabs of the Advanced TCP/IP properties 
box. In addition to that "Enable NetBIOS via TCP/IP"
radio button is set under WINS tab, and under DNS tab
both the radio button "Append primary and connection-
specific DNS suffixes" and the box "Append parent
suffixes of the primary DNS suffix" are set/checked.
The primary DNS suffix is what you enter in System's
tab Network identity->Properties->Advanced in the
field "Primary DNS-Suffix...". The checkbox "Change
DNS-Suffix when changing Domain" is left unchecked.
Works like a charm for all SPs of 2k and XP.
