Re: [Samba] NSS interface lists all domain users but gives error on single user




Hello Rowland,
I changed nsswitch.conf as suggested, but I still have the same result.

[...]
> Providing the there is a user called 'manuelb' in AD, winbind should
> show the user with 'getent passwd AGENZIA+manuelb'

If I list all users, I get all users. Let's display the end of the list
using both wbinfo and getent:

root@kubuntu-test:~# wbinfo -u | tail -2
AGENZIA\lorenam
AGENZIA\manuelb

root@kubuntu-test:~# getent passwd | tail -2
AGENZIA\lorenam:*:10182:8513::/home/lorenam:/bin/bash
AGENZIA\manuelb:*:10183:8513::/home/manuelb:/bin/bash

If I create a file and change its uid to one of these, I see that NSS
does not resolve it:

root@kubuntu-test:~# touch /tmp/ttt 
root@kubuntu-test:~# chown 10183 /tmp/ttt 
root@kubuntu-test:~# ls -l /tmp/ttt
-rw-r--r-- 1 10183 root 0 ott 17 20:54 /tmp/ttt

Even the "id" command does not resolve it. Nor the getent:

root@kubuntu-test:~# id 'AGENZIA\lorenam'
id: ‘AGENZIA\\lorenam’: no such user
root@kubuntu-test:~# getent passwd 'AGENZIA\lorenam'
root@kubuntu-test:~#

This is the complete global section as displayed by testparam:

[global]
	dns proxy = No
	log file = /var/log/samba/log.%m
	map to guest = Bad User
	max log size = 1000
	panic action = /usr/share/samba/panic-action %d
	realm = AGENZIA.LOCAL
	security = ADS
	server role = member server
	server string = %h server (Samba, Ubuntu)
	template homedir = /home/%U
	template shell = /bin/bash
	username map = /usr/local/samba/etc/user.map
	usershare allow guests = Yes
	winbind cache time = 5
	winbind enum groups = Yes
	winbind enum users = Yes
	winbind offline logon = Yes
	winbind refresh tickets = Yes
	workgroup = AGENZIA
	idmap config agenzia : range = 8000-20000
	idmap config agenzia : backend = rid
	idmap config * : range = 3000-7999
	idmap config * : backend = tdb

As you may see, the uids given by wbinfo and getent are in the correct
range.
I do not know how to better debug the problem: I have reised "log
level" in smb.conf but no logging is done during the getent execution.

Thank you,
Giuseppe
