some help needed.

I have/manage a samba share at work. It works fine for everyone except one user. I've tried all I can think now, so now I hope for some new input.

$smbclient --list LOCALHOST

as my user works fine.

$smbclient --list LOCALHOST --user charlottepa

just gives me "session setup failed: NT_STATUS_LOGON_FAILURE".

any other user works just fine, but not this one. I've tried to set the password again with both "passwd" and "smbpasswd -a" and restarted the smbd after the change. No luck.

tail /var/log/samba/log. (the localhost)

[2015/09/15 17:14:09.756209,  0] ../source3/smbd/smbXsrv_session.c:1265(smbXsrv_session_update)
  smbXsrv_session_update: global_id (0xefcb8bb0) store failed - NT_STATUS_INVALID_PARAMETER
[2015/09/15 17:14:09.756269,  0] ../source3/smbd/sesssetup.c:374(reply_sesssetup_and_X_spnego)
  smb1: Failed to update session for vuid=62513 - NT_STATUS_INVALID_PARAMETER

How can I reset her access so that she can use or samba share again?

Server=[Samba 4.1.6-Ubuntu]
It's an Ubuntu 14.04 LTS server. (3.13.0-62-generic)
  • smbpasswd -a is only for adding new users. Have you tried it without the -a ? – Eddie Dunn Sep 15 '15 at 16:16
  • Yes I've tried without the -a option. Doesn't help. – Stefan Ericsson Sep 16 '15 at 9:59

I finally manage to solve the problem. Using "pdbedit -L" I found that names containing Swedish characters didn't display properly. And after changing them with "pdbedit -r --fullname" it now works. I did write the same name again, but now they display correctly. So it looks like perhaps Samba changed the encoding for the user database.

Maybe this can help someone else.

  • This helped me also with Turkish chars in name like ü ğ ş ç – Mert Gülsoy Nov 20 '15 at 16:32

Thanks a lot for your post, it is useful.

I've hit the same situation on CentOS 7 with latest Samba (as of June 2018).

I've accidentally inserted a bad character in the "Full Name" (using chfn command); Samba stubbornly refused to connect from other boxes. The solution was to correct the "Full Name" using pdbedit, as described in your original post.

  • Gotta love stackoverflow for these underappreciated but still given answers! :D – Aiyion.Prime Aug 24 at 8:05

is it possible the user accidentally got disabled? Try re-enabling the user with:

smbpasswd -e <user>

Other than that you could always try:

smbpasswd -x <user>
smbpasswd -a <user>

To delete and re-add the user

  • Interesting effects. I tried -e without success. Then I tried -x. And then it worked with smbclient on the server, but not from her Win7. I then added it again with -a and got back to the same result with "session setup failed". – Stefan Ericsson Sep 16 '15 at 10:02

I just came across the same problem with a different cause: smbXsrv_tcon_global.tdb had reached 4GB in size and couldn't grow any more.

Deleting /var/lib/smbXsrv_tcon_global.tdb and restarting Samba cured the problem.

I believe that this is related to a bug in Samba which occasionally causes a crash in smbXsrv_session_logoff_all when a client disconnects.

This was an a RHEL 7.1 system running Samba package version samba-4.2.3-10.el7.x86_64.
