[Samba] winbind authentication

[Lars Kirchhoff]

hello,

i'm trying to use winbind to authenticate windows user on a linux
machine.
so far I played a while with everything and got winbind running. I did
all test described in the winbind.html, but still cant login from
windows
to the linux machine. 

I did the following commands successfully:

 a) wbinfo -u                   --> list of users
 b) wbinfo -g                   --> list of groups
 c) wbinfo -t                   --> secret is good
 d) wbinfo -a username%password --> plaintext password authentication
succeeded
 e) wbinfo -n username          --> get the SID 


What is still going wrong, that i can't authenticate? 

I'm using samba 2.2.8. Here is my smb.conf: 

--------------------------------------------------------
[global]

   netbios name = SambaHead
   server string = Samba NAS Head

   socket address = xxx.xxx.xxx.xxx
   interfaces = xxx.xxx.xxx.xxx/255.255.255.0

   workgroup = xxx
   security = domain
   password server = xxxxxx
   os level = 2

   encrypt passwords = yes

   wins support = no
   domain master = no
   local master = no

   winbind separator = "\"     # i've tried also with +
   winbind uid = 10000-20000
   winbind gid = 10000-20000
   winbind enum users = yes
   winbind enum groups = yes

   load printers = no
   show add printer wizard = no

   log file = /usr/local/samba/var/log.smb
   max log size = 100000
   log level = 3

[xxxx]
   comment = xxxx
   path = /export/xxxx
   read only = no

[xxxx]
   comment = xxxx
   path = /xxxx/xxxx
   read only = no
