[Samba] RID idmap backend: difficulties looking up a user by its uid

[Jakob Ahlin]

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:

Any ideas?
