Samba automatically adding XP Pro client to PDC not working

Robert Hausler — Thu, 12 Jan 2006 07:44:57 GMT

HI,

You no doubt get a lot of this.

I have set up a rh-es4 with samba 3 as pdc
the prob i have is if I manually adduser pc_machine and vipw the pc_machine to pc_machine$
I can then join XP Pro Client pc_machine to pdc - works fine. and the pc_machine$ entry is automatically added to smbpasswd file.

However If I try to add XP Pro pc_machine to pdc without manually adding the machine name it reports "the user name could not found"

I have also found I cannot adduser pc_machine$ I have to adduser pc_machine and then vipw to manually put the $ at the end of the machine name.

Manually is ok for one or two machines but 20 :)

your help invaluable.

Shalom Robert,

This may be a problem with the Windows client.

Is the networking setup match the domain name of the Samba PDC?

Is the machine patched sufficiently to work with Samba?

Putting a machine account into the PDC under Samba is not such a onerous requirement. To make a Samba server join a network, its sometimes requires to make a machine account on the Windows PDC.

I think that you don't configured the add machine script parameter. You must configure that. See also:

I have set the typical signorseal registry edits on the client.

I also have an add machine script which is the same as what I used when manually creating the account.

I can't help but keep thinking that it might have something to do with the fact that I cannot add a user with a $ on the end even manually without using vipw to append the $ manually.

should I includ my smb.conf - would that be helpful.?

I don't know why you can't add a user with $. With useradd "username$" (double quoted) it works on my system.

Hey Rob!

I'm shocked, you didn't call first :P

Anyway, some details if you could.

I've got a RHES4U2 system here (go VMWare), and I, like the others here, can add user$ no problems.

So, what are the SELinux settings currently set to? (/etc/selinux/config). Enforcing/Targeted? Or [Permissive|Disabled]/Targeted?

What versions of the packages 'samba' and 'selinux-policy-targeted' do you have?

I'm running samba-3.0.10-1.4E.2 and se-policy-targeted-1.17.30-2.110.

I thought PAM might have some control over the user-adding stuff, but it doesn't, so there goes one whole line of thinking.. And I'm pretty sure with what you've said thus far, it's not 'cause you're storing the users in an LDap or other database.

.. Anyway, try the SELinux path first .. I'll think some more ..

I think that winbind is only needed if you want to authenticate services with a Windows Domain Controller.

Also, i'm not sure about using the same ID for all machines, use instead:

add machine script = /usr/sbin/useradd -s /bin/false -d /home/nobody %u

The biggest problem I have is that I cannot adduser ... pcname$ from the command line. I have to adduser .. pcname and then add the $ by manually adding it using vipw. i have also tried using "pcname$"

What if you use

useradd machine\$

That works on my system too.

Also, when you run net groupmap list, do you see Domain Admins (RID 512), Domain Users (RID 513) and Domain Guests (RID 514)?

Robert Hausler — Thu, 19 Jan 2006 15:07:03 GMT

If i try useradd pcname\$ i get 'invalid user name' and yes i have the Domain Admin,Guest and user in the net groupmap list.
