Hi,

I want to move from Samba 2.2.12 to 3.0.10. I downloade the 3.0.10
sources and compiled them (Solaris 8). Everything went fine. After the
install, I tested the new 3.0.10 Samba with the old smb.conf from 2.2.12
(the docs say this should work). I could not log in anymore.

I switched back to 2.2.12 and tried the 3.0.10 install on a Suse Linux
8.0 - with the same results. I used most parts from the solaris
smb.conf.

This is the Samba config of the Linux sytem. It acts as samba server,
and later for testing as client too.

[global]
workgroup = ERS
netbios name = sambaserver
os level = 0
name  resolve order = host lmhost wins
encrypt passwords = Yes
guest account = Nobody
map to guest = Bad User
hide dot files = yes
unix extensions = yes
username map = /etc/samba/smbusers
log file = /var/log/samba/%m
log level = 3
security = server
password server = passwordserver
socket options = SO_KEEPALIVE IPTOS_LOWDELAY TCP_NODELAY
local master = No
wins support = No
wins server = winsserver
character set = ISO8859-15
client code page = 850
veto files = /*.eml/*.nws/riched20.dll/*.{*}/
...

The server is not member in our company domain EMEA. At the moment it is
not possible to use 'security = domain', so we use 'security = server'.
The server is in the workgroup ERS (no DC!), witch is the name of our
department.
Authentication happens against the EMEA password server with the
UID/PASS users have in the EMEA domain. Mapping between the unix UIDs
and domain UIDs is done with the option 'username map'. This worked fine
with 2.2.12.

I did the tests on the linux system (both client and server!).
ralfgro is my EMEA domain account, rg the local unix account.

I also did a trace with ethereal:

---> Samba 2.2.12
Session Setup AndX Request, User: EMEA\RALFGRO
..
Account: RALFGRO
Primary Domain: EMEA
..

---> Samba 3.0.10
Session Setup AndX Request, User: ERS\RALFGRO
..
Account: RALFGRO
Primary Domain: ERS
..

Why does samba 3.0.10 turn over the wrong workgroup/domain parameter (ERS)
to the password server?

If I change the workgroup in the smb.conf file to EMEA it works. But the  
                                       server should stay in the ERS
workgroup. Users always set the                                           
      workgroup/domain name during the login process. Most of the windowsstandard clients are in the EMEA domain, so this is no problem.

This worked fine in 2.2.12. Have there been any changes in Samba 3.x.x
that could be important in this case? I know that Samba 3 comes with
winbind, but since the server is not member of the EMEA domain, I can't
use it (or am I wrong in this?).

I'm a bit lost...

Ralf
