Can you try a "useradd nl-msek$" please?

Volker

Closing as invalid, this is not a bug. The log file says 

 User NL-MSEK$ in passdb, but getpwnam() fails!

which means that the user nl-msek$ (the machine account) is not in the nsswitch user database. This works as designed.

Volker

Hi Volker,

I have this user in /etc/passwd

nl-msek$:x:537:540::/dev/null:/bin/false

but don't have NL-MSEK$ in /etc/passwd

pdbedit -L -v NL-MSEK$ gives me:

Unix username:        NL-MSEK$
NT username:

So i have nl-msek$ but not NL-MSEK$ in /etc/passwd ? This is a glitch ?

I have another machine: NL-JKNAPIK$ which is running WindowsXP SP3 and there aren't such floding mesagess:

In /etc/passwd

nl-jknapik$:x:532:535::/dev/null:/bin/false

an pdbedit -L -v NL-JKNAPIK$

Unix username:        NL-JKNAPIK$

So where lies the problem ?

And one thing:

In /var/log/messagess i have: 

Oct 11 13:09:11 serwergr smbd[6411]: [2010/10/11 13:09:11,  0] auth/auth_sam.c:444(check_sam_security)
Oct 11 13:09:11 serwergr smbd[6411]:   check_sam_security: make_server_info_sam() failed with 'NT_STATUS_NO_SUCH_USER'
Oct 11 13:09:11 serwergr smbd[6411]: [2010/10/11 13:09:11,  0] auth/auth_sam.c:444(check_sam_security)
Oct 11 13:09:11 serwergr smbd[6411]:   check_sam_security: make_server_info_sam() failed with 'NT_STATUS_NO_SUCH_USER'
Oct 11 13:09:11 serwergr smbd[6411]: [2010/10/11 13:09:11,  0] auth/auth_sam.c:444(check_sam_security)
Oct 11 13:09:11 serwergr smbd[6411]:   check_sam_security: make_server_info_sam() failed with 'NT_STATUS_NO_SUCH_USER'

then i checked pid 6411:

smbstatus -b

6411      jadwigadrwiega  jadwigadrwiega  nl-jdrwiega  (192.168.4.4)

So why in log of machine 192.168.4.4 (NL-JDRWIEGA$) is so many errors about user NL-MSEK$, where NL-MSEK$ is 192.168.4.1 ?

Volker, could you please look closer at this situation ? 

I have samba network for years, last summer i added only 3 machine with windows 7 Professional 64-bit. User, that login to domain to this samba, can get all the files: can read, write, etc. Only straneg is this for me, that all seems to be ok with my configuration.

Machin with Win7 were add with instruction from samba wiki about joing windows 7 to samba PDC.

Machine account in question are in /etc/passwd - so i don't undestand, why samba flodding my /var/log/messages states, that there isn't such machine account.

I use samba 3.4.9 from sernet (switched back from sernet samba 3.5.5).

 

Can you please add those users ending in $ to /etc/passwd and retry? Please report your results here.

Thanks,

Volker

Hi Volker, i had upgrade from samba 3.5.6 to 3.5.8 and these errors went away. Now my /var/log/message is clear and smbd process not floding with this info: NT_STATUS_NO_SUCH_USER

So i assume - this version has fixed this nasty bug. I think, You can close this buginfo.
