Samba join domain

samba_pc can ping dompdc and dompdc can ping samba_pc (using netbios names). Using lmhosts.

Try to add -U <administrator> when you try to join. Also check that the machine hasn't been allready added to the domain since adding it twice will get you an error.
In order to be able to access the samba server you have to have also a mapping beetwen the NT users and the linux users, since the rights check is done by the linux machine according to linux rules. See smbpasswd(5) man page.
You can also use the winbind daemon in order not to have linux users, but that's a little bit more complex.

Oki. Let's say that samba_pc is already added to the domain.  I added the user tmathies with "smbpasswd -a tmathies" command.. and gave it a different password than the one in the domain.

When I try to enter the share, I use the user "tmathies" (not "DOM\tmathies") and the password that I have in the domain. Doesn't work.

Does it first check the smbpasswd file? I thought it would ignore that way of authentication.

No, IT WILL CHECK the smbpasswd in order to get the uid for tmathies. So you need to have a linux user tmathies and a user in smbpasswd tmathis with the same uid as the linux one.
But this should be Ok since smbpasswd -a worked. Check also that the user isn't disabled.

Oh, don't assume that the machine is in the domain. Make sure it's in the domain or it won't work.

ok. In server manager the samba_pc is in the list of machines in the domain.

Note: the user "tmathies" has a different password in the smbpasswd than in the domain. Thought that would f@# up the authentication.

I try to enter \\samba_pc\tmathies

tmathies and domain password -> does not work
tmathies and local (smbpasswd) password -> works

?

Maybe there's something wrong with smb.conf:
workgroup = your domain
security = domain
password server = your PDC
encrypted passwords= true (or maybe false, I don't remember exactly, but it matters)

FYI: it looks like the machine is in the domain, 'cause it's listed in server manager.

Think we've got a better clue here:
last line in /var/log/samba/dttmathies01.log:
 Domain password server not available.

I can ping dompdc and in smb.conf dompdc is the one in password server.

Can't samba use a netbios name? Do i have to enter dompdc.dom.com?

/T

Tried again, and latest from /var/log/samba/machinename.log:

Have a look at previous messages. Does it say anything about a TRUST_ACCOUNT ?

The log file does not say anything about a TRUST_ACCOUNT. In what log file would that be?

Sorry about not changing any names here, but too much of a hazzle. Seems to be a problem between the pdc and the samba server. Should I just delete the machine account in the domain and then add my samba server again?

Yep.

I had this error before and it took me a looong time before I figured it out then

The command should be:
smbpasswd -j DOM -r FRSPDC -U Admin...
USE THE NETBIOS NAME for PDC not the FQDN or you'll get back here.
You used the full domain name when you registered the machine before, haven't you ?

Hmmm.. doesnt look too good either:

[root@machine samba]# smbpasswd -j MyDom -r frspdc -U username%password
Unknown parameter encountered: "ldap ssl"
Ignoring unknown parameter "ldap ssl"
Error connecting to frspdc

Try a testparm. The error message has something to do with smb.conf.
BTW are you using ldap or ssl anywhere in you configuration ?

Stupid question; how to I do a testparam?

Turned off the ldap ssl (pretty far down in the smb.conf).. restarted smbd, but still get the "ignoring unknow..blabla".

Sorry it's testparm. It's just an utility that checks you smb.conf file

Hope ee has alot of diskspace, cause here's my file:

The ip configuration is using dhcp..

Can you see anything wrong in this file?

I'm sorry, I have an emergency since yesterday afternoon, but  this looks like a testparm output. It looks Ok at the first glance, but how's you real config file ?
It should be a lot simpler than that.

No problem mate ;)
U get 300 points for it whenever we finish. No emergency. Shall I copy the whole smb.conf file to this case?

   status = yes
   ldap ssl = no

You can also change the password server to "*", it will try to find a PDC on its own.
Also first try to get the server registered first, since some authentication tokens are set at this point. it's useless to try anything until this is done.

Got this;
Error connecting to frspdc
Unable to join domain FRS.

Try to use nmblookup -d4 frspdc. You can use different debug level, but 4 is quite ok usually.

added interface ip=172.16.16.21 bcast=172.16.17.255 nmask=255.255.254.0
bind succeeded on port 0
Socket opened.
querying frspdc on 172.16.17.255
name_query failed to find name frspdc

Looks like we've found the problem =)
However, we are using wins over dns here in the company. Should I add frspdc to local host file, or tell samba to use wins over dns? It works to ping it..

I think I need to have samba use my wins server?

Added

 wins support = no
     wins server = 129.22.4.10
     name resolve order = wins hosts lmhosts bcast

to smb.conf.
Joining domain works!
Will test the rest now =)

Works fine now!

Ok, I'm back.

I'm also glad that it works and thanks for the points.
Just for my curiosity: what the ip of frspdc ?

172.16.8.134

Aha. That would have saved some time.
Tipical browsing is done in M$ by brodcasting, and since brodcasts do not pass throgh routers, you can never find a windows machine unless you use wins or lmhosts.

Yep, I know. But since the linux config runs wins, I would think that all services also did. Anyways; guess this paq is helpful for alot of people =)

Thanks alot!

My pleasure
