[solved] Samba doesn't start - Unregistered Authentication Agent f...

Hi,

suddenly my samba won't start anymore.

systemctl status smbd.service delivers:

In my case nmbd doesn't start, I have seen message in /var/log/samba/log.nmbd

2015/09/11 08:52:22.213327,  0] ../lib/util/util.c:285(directory_create_or_exist_strict)
  invalid permissions on directory '/var/cache/samba/msg': has 0700 should be 0755

I did:

chmod 0755 /var/cache/samba/msg
systemctl start nmbd
systemctl start smbd

Samba have been started. Good luck!

sbt1 · 2015-09-11 14:36:01

You, sir, are my hero! Thank you very much, that was the problem!

I would have never solved this on my own.

heimer16 · 2015-09-11 15:54:44

I seem to be having the same issue, although there was no info in any of the log files. I tried chmod the /var/cache file, but still no go. I also did a fresh install on a machine that did not have it installed previously and it gives me the same error.

Any other ideas?

Same problem here, Samba used to work fine a week ago, and it now fails to start. Here's my journalctl -xe

Like heimer16, my /var/log/samba/ folder has nothing fresh to report (the most recent item that ls -latr yields is from two days ago).

Any idea? Thanks for your help.

heimer16 · 2015-09-12 05:00:47

Got it working somehow. I resotred the default smb.conf and completely removed /var/log/samba and /var/cache/samba. Then, from another thread https://bbs.archlinux.org/viewtopic.php?id=195907 someone suggested running

# smbd -i

(as root) to start the daemon without using systemd to see if there were any errors. I got some error about /etc/printcap, but it seemed to be working. I killed that process and then did systemctl start smbd and then it worked. (I may have also done a systemctl daemon-reload in there as well). I think running smdb -i generated what it needed in /var/log or whatever. Got it working now on two different machines that were having the same issue.

Hope that helps.

Yes! Thanks for the tip of starting smbd interactively as root, that reported the problem (which was neither in journalctl -xe, nor in any /var/samba log):

[root@x ronj]# smbd -i
smbd version 4.3.0 started. Copyright Andrew Tridgell and the Samba Team 1992-2015
invalid permissions on directory '/var/cache/samba/msg': has 0700 should be 0755

One chmod later, samba starts fine; not sure why the permessions were borked . Thanks again for the help!

jclark · 2015-09-12 17:15:37

Thank you very much.

smbd -i found "invalid permissions on directory '/var/cache/samba/msg': has 0700 should be 0755" and as you say, a quick chmod fixed it.

scwalla · 2015-09-15 18:08:51

I had the same problem. chmod fixed it. Rather disturbing that the error is not logged when nmbd and smbd are started from systemd. Anyone know why the invalid permissions error is not getting logged?

tilex · 2015-10-05 21:08:15

Thank you! I also had the same problem. Everything was working a few weeks ago and then suddenly stopped working. Here's what I did to fix it:

sudo smbd -i
sudo chmod 0755 /var/cache/samba/msg
sudo systemctl start smbd.service
