[Samba] winbindd : Error message when login into the sama share ( nsswitch/winbindd_passdb.c:sid_to_name(126) )

[Benjamin Pavie]

Hi Everybody,

I have some error message each time someone connect to my samba share:
May  5 11:03:52 vishnu winbindd[10901]: [2011/05/05 11:03:52, 0]

Here is the command to access to the samba share:
smb://vishnu.dhcp.swmed.org/share/

Here is my smb.conf file:
grep -Ev "#|^;" /etc/samba/smb.conf | uniq

[global]

   workgroup = STANILAB
   password server = vishnu.dhcp.swmed.org
   security = share
   idmap uid = 16777216-33554431
   idmap gid = 16777216-33554431
   template shell = /bin/false
   winbind use default domain = true
   winbind offline logon = true



disable spoolss = yes
server string = Samba Server Version %v

netbios name = VISHNU

passdb backend = tdbsam

domain master = yes
preferred master = yes
os level = 35

load printers = no
cups options = raw
printcap name = /dev/null
disable spoolss = yes

username map = /etc/samba/smbusers
guest account = nobody

[homes]
comment = Home Directories
browseable = no
        read only = yes

[share]
comment = Guest share
path = /home/share
browseable = yes
read only = yes
guest ok = yes


And the domainsid:

net getdomainsid
SID for domain VISHNU is: S-1-5-21-801058460-1949192029-466506960
Could not fetch domain SID

I probably mis-config something but I don't see what...
