Hi list,

I have tried with all my might to get a samba3 server (Ubuntu 12.04.1 LTS) to 
join a Windows 2003 domain as a member server, without any luck. I have 
used,from memory, the official way of doing this (aka, from the samba.org 
website). No matter what settings I use in smb.conf, the server always joins as 
a domain controller. This doesn't seem to break the domain how ever. All I am 
after is that my users do not need to enter a username/password for access from 
a domain PC to shares on my Linux box.

Any pointers please or is this intended as the server does single sign?
If you can list exactly the steps you took, we might be able to help.

But to answer your question:  Yes, Samba will happily join Windows 2003
as a domain member.  The key command is 'net ads join'.

Hi Andrew,

Sorry for the delay in my reply, things has been hectic closing down for the holidays. In a nut shell, there is what I do/did:

1) apt-get install samba winbindd krb5-user
2) Configure smb.conf as per :

[global]

   workgroup = WORK
   realm = WORK.LOCAL
   preferred master = no
   server string = Linux Test Machine
   security = ADS
   encrypt passwords = yes
   log level = 3
   log file = /var/log/samba/%m
   max log size = 50
   printcap name = cups
   printing = cups
#   winbind enum users = Yes
#   winbind enum groups = Yes
#   winbind use default domain = Yes
   winbind nested groups = Yes
   winbind separator = +
   idmap uid = 2000-20000
   idmap gid = 2000-20000
   template shell = /bin/bash
   veto files = lost+found

3) Configure krb5.conf:
[libdefaults]
        default_realm = WORK.LOCAL

[realms]
        YPG.LOCAL={
        kdc=DC.WORK.LOCAL
        }
[domain_realm]
        .kerberos.server=WORK.LOCAL

4) Restart Samba/Winbind
5) In /etc/nsswitch.conf add winbind to passwd and group
5) Join the domain : net ads join -U <my_admin_account>
6) kinit <my_admin_account>

From then, users can connect to the shares on the server using Single Sign On. The "issue" is that if I look under my Active Directory, the server will state that it is a "Domain Controller". Running the usual DC Info tools they seem to think the domain is ok. I would prefer to have the server say Member server, rather than DC :)

I would like to send you a screenshot of what "Active Directory Users and Computers" shows but this will be hard to do remotely.

Thanks,

Pieter

P.S. Good work on the AD integration btw, I am using the above for Squid aswell and it's pretty neat ! :)
