[Samba] Winbind issue using samba 3.6.3

[Heather Choi]

Looks like you have a potentially conflicting idmap block here:

idmap backend = rid:DOMAN=10000-20000
and here:
idmap uid = 10000-20000
idmap gid = 10000-20000

This is more contemporary with Samba 3.6:

    idmap config * : backend = tdb
    idmap config * : range = 20001-30000

    idmap config DOMAIN : backend  = rid
    idmap config DOMAIN : range = 10000-20000
    idmap config DOMAIN : base_rid = 0

[me at LINUX ~](14)$ wbinfo --user-info=testuser
testuser:*:13102:1513:Test User:/home/testuser:/bin/bash
[me at LINUX ~](15)$ getent passwd testuser
testuser:*:13102:1513:Test User:/home/testuser:/bin/bash

(My low-end range starts lower than 10000, btw).

Also, you sure you want to keep your idmap range within just 10000?  
Seems quite low to me.

The only issue here was due to dependency issues downgrading to samba 3.5.4 resulted in libwbclient0 being downgraded which resulted in the removal of ubuntu-desktop.
