[Samba] 'valid users' does not accept my users, but my groups

[Markus Fischer]

Hi,

I'm using Version 3.0.10-Debian and have winbindd running for auth 
against our W2K TEST-DOM. I've set up shares which only some groups have 
access granted. System is runnig fine a few weeks when I now discovered 
when I want grant access to only one user, it doesn't work.

The configuration for this share is:
[testshare]
     path = /data/test
     public = no
     writeable = yes
     browseable = yes
     create mode = 0777
     force directory mode = 0775
     force create mode = 0666
     force user = www-data
     force group = www-data
     valid users = mfischer

The logfile tells me:

[2005/04/27 10:44:05, 2] auth/auth.c:check_ntlm_password(305)
   check_ntlm_password:  authentication for user [mfischer] -> 
[mfischer] -> [TEST-DOM"mfischer] succeeded

[2005/04/27 10:44:05, 2] smbd/service.c:make_connection_snum(314)
   user 'TEST-DOM"mfischer' (from session setup) not permitted to access 
this share (testshare)

When I use groups, e.g.
     valid users = @development
and my user 'mfischer' is in this group, it works without problems.

I've tried different syntaxes like
   TEST-DOM\mfischer
   TEST-DOM"mfischer (because it's written this way in the logfile)
   TEST-DOM+mfischer (because of the winbind separator)
   TEST-DOM/mfischer
none of them worked.

My pam.d/samba looks like:
# from  common-auth
auth    sufficient  pam_winbind.so
auth    sufficient  pam_unix.so nullok_secure use_first_pass
# from common-account
account required    pam_unix.so
# from common-session
session required    pam_unix.so
session required    pam_mkhomedir.so    skel=/etc/skel/ umask=0002

any suggestions or other information I can provide?

thanks,
