How to debug Samba authorization (authentication) procedure

  • 772

I'm running a small home network linux-based server which acts as an internet router, torrent client and file server. I have problems connecting Windows clients to server Samba shares ('user name or password is invalid'). How can I enable logging of all stages of Samba authentication/authorization procedure, such as "client connected", "client provided username ... and password ..." etc. so I can find out what exactly is wrong since I'm sure I'm providing proper username and password?

    • set logging in smb.conf to level 2 or higher, e.g.

      log level = 3

    • watch log files - usually in /var/log/samba/

      tail -F /var/log/samba/log.[client-machine-name]

    • look for "authentication for user" ... and context

  2. In my case no logs were written at all but login kept failing.

    My config file was not as valid as i'd expected. With sudo testparm i could see that the samba config wasn't valid at all. A similar output could be seen in the smbd service's status via sudo systemctl status smbd.service.
