samba - Aug 2009 - RID idmap backend: difficulties looking up a user by its uid

Hi,

I'm having a problem using the RID idmap backend with Winbind. Having 
configured NSS with the Winbind module, I can use "getent passwd" to 
look up a user by its username, but not by its uidnumber. However, if I 
first do a lookup using the username or run wbinfo on the user 
(specifying either the username or uid), and then try "getent passwd" 
with the uidnumber, I get the correct result.

See here:
debianrid:~# getent passwd 161907
debianrid:~# wbinfo --uid-info 161907
lokr:*:161907:100513:Lovisa Kristiansson (lokr):/home/WBLABB/lokr:/bin/sh
debianrid:~# getent passwd 161907
lokr:*:161907:100513:Lovisa Kristiansson (lokr):/home/WBLABB/lokr:/bin/sh
debianrid:~#

Related smb.conf lines:
   idmap backend = rid
   idmap uid = 100000-10000000
   idmap gid = 100000-10000000
   winbind use default domain = yes
   winbind enum groups = yes
   winbind enum users = yes

Version information:
   Version 3.3.7-SerNet-Debian

 From log.winbindd-idmap:
[2009/08/12 10:13:58,  0] lib/module.c:do_smb_load_module(69)
  Module '/usr/lib/samba/idmap/rid.so' initialization failed: 
NT_STATUS_OBJECT_NAME_COLLISION
[2009/08/12 10:13:58,  1] winbindd/idmap.c:idmap_alloc_init(580)
  could not find idmap alloc module rid

Any ideas?

Regards,
Jakob

I believe smb.conf line should be
    idmap backend = rid:DOMAIN=100000-10000000
