Samba issue

[brononius]

Hey,

Last days, I played around with the users and the group they belong to. And did also some apt-get udpates. And now I can't login anymore with samba protocol. Apparantly the user don't exist anymore?

The clientPC = Windows 7 & Linux Mint 17
The user = brientje

  check_ntlm_password:  Authentication for user [Brientje] -> [pluto_brientje] FAILED with error NT_STATUS_NO_SUCH_USER
  check_ntlm_password:  Authentication for user [Brientje] -> [pluto_brientje] FAILED with error NT_STATUS_NO_SUCH_USER
  check_ntlm_password:  Authentication for user [Brientje] -> [pluto_brientje] FAILED with error NT_STATUS_NO_SUCH_USER
  check_ntlm_password:  Authentication for user [Brientje] -> [pluto_brientje] FAILED with error NT_STATUS_NO_SUCH_US..........

pluto_brientje = brientje

pluto_brientje:10001:DD4D27348EDCBEBA93E28745B8BF4BA6:3D83FDBC71EF25E316C6BADA8AFF8D19:[U          ]:LCT-00000001:,,,

brientje:x:1001:1003:Brientje User,,,:/home/brientje:/bin/bash
pluto_brientje:x:10001:10001:,,,:/home/user_2:/bin/false

uid=1001(brientje) gid=1003(brientje) groups=1003(brientje),1001(public)

uid=10001(pluto_brientje) gid=10001(pluto_brientje) groups=10001(pluto_brientje),1001(public),1003(brientje)

Any idea / suggestion?

Not sure if this is the solution, but it seems to help to run 'smbpasswd -a'

smbpasswd -a pluto_brientje
   password:
   Retype new SMB password:
Added user pluto_brientje.

Afterwards, i'm able to login with the samba clients.

looks like you've updated the samba server to a version using a different passwd database/ passwd storage.

[brononius]

you've updated the samba server

I can't recall that I've done it specially for something. Just some apt-get updates, and I'm playing around with backuppc.

For me, it's working now, and I don't have so many users, so it's a quick solution.
But if I can do/test anything, let me know...
