Re: unable to log on to Samba shares remotely

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Some additional information, should this be helpful.

Our servers are all on subnet 192.168.5 and are running Solaris 10, Windows PCs are on 192.168.3.
I didn't use any kind of mapping when creating the accounts. All I used was "pdbedit -a" without any other parameter specified.

The global section of the smb.conf I included contains all lines that are entered. Security = USER is therefore what we use.


Kind regards,

Dirk Claesen

Thanks for the quick reply!

The server from which I tried to connect remotely is located within the same subnet. The Windows PC is in another subnet.

All users exist since years in the /etc/passwd file. The four users that were using the shares successfully in the past have UID 200, 230, 250 and 300. (user1 is one of these users)
The two users I need to add have UID 350 and 400. (user2 is one of these)
Each of these users is in a different Unix group.

User1 for which I included the output of pdbedit has UID 250, user2 has UID 350.
I cannot run wbinfo for these users as I'm not using winbind.

Pdbedit returns SIDs 1400, 1460, 1500 and 1600 for the "old" Samba users and 1004 and 1005 for the two users I tried to add.

I also ran the id command for the users but that gave the same UID as the ones I extracted directly from the passwd file.

Is there anything else I can check?


Kind regards,

Dirk Claesen

When you say "remotely" you mean from another computer.  Or do you mean
from another subnet?



If you recreated both samba accounts, and the two accounts behave
differently, then the problem may be in the underlying unix account. 
Are the unix accounts defined in /etc/passwd?  

I also find it interesting that the two users do NOT have user SID's
that are sequential (or at least in a closer range.)  Are you using
idmap to allocate


Can you run
    #    wbinfo -n user1
    #    wbinfo -n user2

This will show the user sids of the users

   # wbinfo -s sid_of_user_one
   # wbinfo -s sid_of_user_two


The name-to-sid and sid-to-name assignment should match up.

Also try the following
    #id user1
    # id "YOURDOMAIN\user1"  (if you are using winbind)

    #id user2
    # id "YOURDOMAIN\user2"

However, when I try to connect from another Samba 3.5.6 server or from a Windows XP PC I get respectively a "session setup failed: NT_STATUS_LOGON_FAILURE" or "System error 1326 has occurred. Logon failure: unknown user name or bad password." error message. (there is no firewall blocking any ports between the servers or between the PC and server1)

This resulted in the two tdb files to be recreated after which I added user1 and user2 again using pdbedit -a. Again, I could only access the shares using either of these users directly from server1 but not from any of the other servers.

With the initial tdb files back in place, I can login again remotely using user1 but not with user2 (even after I added the account again). Repeating my test connecting locally to the share, I noticed I am not able to connect locally with user1 to projA_dirs while it is possible to do it from the other server. I can connect locally using user2.
