[Samba] wbinfo -u/-g/-n works, but not 'wbinfo -i' or 'id'

[Horacio G. de Oro]

Hi! I'm trying to add a member to be used as fileserver, following the
guides at:
- https://wiki.samba.org/index.php/Setup_a_Samba_AD_Member_Server
- https://wiki.samba.org/index.php/Using_RFC2307_on_a_Samba_DC

The AD server has been in use for month, but I can't get user
information from the new member. The new member was joined to the
directory, and nsswitch was configured. Running 'id username' returns
'No such user'.

Running 'wbinfo -u' and  'wbinfo -g', 'wbinfo -n username' and 'wbinfo
--sid-to-uid' works OK. Also 'wbinfo --online-status' and 'wbinfo
--ping-dc'

But, when I try 'id username', or 'wbinfo -i username', it fails with
WBC_ERR_DOMAIN_NOT_FOUND

$ wbinfo -i username
failed to call wbcGetpwnam: WBC_ERR_DOMAIN_NOT_FOUND
Could not get info for user username

$ wbinfo -n username
S-1-5-21-3087569779-2873525441-767630994-1118 SID_USER (1)

And using '--sid-to-uid' I got the UID:

$ wbinfo --sid-to-uid S-1-5-21-3087569779-2873525441-767630994-1118
10000

The UID was added using ADUC, just to the user I'm using for the tests.

I've confirmed the information is in the directory, since I can see it
when dumping the user information (from the AD server):

$ ldapsearch -x -h 127.0.0.1 -b DC=mydomain,DC=com,DC=ar -D
CN=Administrator,CN=Users,DC=pea,DC=com,DC=ar samaccountname=username
-W
(...)
msSFU30NisDomain: mydomain
uidNumber: 10000
loginShell: /bin/sh
unixHomeDirectory: /home/username
gidNumber: 10000
msSFU30Name: username
unixUserPassword: ABCD!efgh12345$67890
uid: username
(...)

The full log is available at:
https://gist.github.com/hgdeoro/3a8cbce9defc43bc5699.

The new member configuration file is at:
https://gist.github.com/hgdeoro/4e6204b482f0d790cc8b

I'm using CentOS 6 in both servers, with Samba 4.0.22 from SerNet.


Am I missing some step or configuration? Any help will be appreciated.

Thanks in advance

Horacio
