[Samba] getent group 'Domain Users' hangs

[Marcel Mary]

The setup:
  - Samba 2.2.6 with winbind on Solaris 9.
  - PDC on NT 4.0 SP6
  - fresh install in test lab

Solaris host correctly authenticates users.
wbinfo -u returns all users
wbinfo -g returns all groups
getent passwd returns all users
getent group returns all groups except Domain Users!
wbinfo -n 'Domain Users' returns <SID-of-Domain-Users> 
wbinfo -G 10000 returns <SID-of-Domain-Users>
wbinfo -s <SID-of-Domain-Users> returns Domain Users

getent group 'Domain Users' hangs forever as does an ls -l on
any new file created by a user belonging to that group.

nscd.conf is the default one from the Solaris install.
nscd -i group or even terminating nscd didn't help.

The smb.conf:
[global]
log level = 3
workgroup = MARCO
netbios name = SELDON
admin users = root
encrypt passwords = yes
security = domain
winbind separator = |
winbind enum users = yes
winbind enum groups = yes
winbind uid = 10000-20000
winbind gid = 10000-20000
winbind use default domain = yes
password server = *

[public]
comment = Public Stuff
path = /u02/smbdata/public
guest ok = no
write ok = yes
