[gentoo-user] sudo -l strange behavour when used via LDAP

[Giampiero Gabbiani]

Hi all,
I configured sudo in order to use LDAP and set the corrisponding defaults on 
the DIT set to ignore_local_sudoers.
After populating the DIT with the rules, sudo works perfectly but I have a 
problem with the list options of sudo (-l).

It seems like sudo -l for NORMAL users (i.e. not root) doesn't print the 
corresponding matched rule when this comes from LDAP. More exactly it matches 
the rule (and actually the user can perform the commands he is enabled to do) 
BUT they are not shown with the list option.

After setting the sudoers_debug to 2 in /etc/ldap.sonf.sudo I obtain the 
following:

giampa@athena ~ $ sudo -l
LDAP Config Summary
===================
host             vesta.homenet.telecomitalia.it
port             -1

sudo: ldap_set_option(LDAP_OPT_HOST_NAME, vesta.homenet.telecomitalia.it)
sudo: ldap_set_option: debug -> 0
sudo: ldap_set_option: ldap_version -> 3
sudo: ldap_sasl_bind_s() ok
sudo: found:cn=defaults,ou=SUDOers,dc=gabbiani,dc=org
sudo: ldap sudoOption: 'ignore_local_sudoers'
sudo: ldap sudoHost 'ALL' ... MATCH!
sudo: ldap sudoOption: '!authenticate'
sudo: user_matches=1
sudo: host_matches=1
sudo: sudo_ldap_lookup(52)=0x02
Runas and Command-specific defaults for giampa:


sudo: ldap search '(|(sudoUser=giampa)(sudoUser=%giampa)(sudoUser=%wheel)
(sudoUser=%floppy)(sudoUser=%audio)(sudoUser=%cdrom)(sudoUser=%video)
(sudoUser=%usb)(sudoUser=%portage)(sudoUser=%plugdev)(sudoUser=%netusers)
(sudoUser=%cvsadmin)(sudoUser=ALL))'
sudo: ldap sudoHost 'ALL' ... MATCH!
sudo: ldap search 'sudoUser=+*'

The root user instead correctly prints the list informations:

athena ~ # sudo -l

Runas and Command-specific defaults for root:


sudo: ldap search '(|(sudoUser=root)(sudoUser=%root)(sudoUser=%bin)
(sudoUser=%daemon)(sudoUser=%sys)(sudoUser=%adm)(sudoUser=%disk)
(sudoUser=%wheel)(sudoUser=%floppy)(sudoUser=%dialout)(sudoUser=%tape)
(sudoUser=%video)(sudoUser=ALL))'
sudo: ldap sudoHost 'ALL' ... MATCH!
sudo: ldap sudoHost 'ALL' ... MATCH!
sudo: ldap search 'sudoUser=+*'
User root may run the following commands on this host:
    (ALL) ALL
    (ALL) NOPASSWD: ALL

The expected behavour for NORMAL user is instead (this comes from another 
machines running mandriva 2010.1):

giampa@vesta ~ $ sudo -l
Runas and Command-specific defaults for giampa:
    ignore_local_sudoers

User giampa may run the following commands on this host:
    (ALL) NOPASSWD: ALL

Is it a bug ? Is there anyone that experimented the same? Is there anything 
that I to set in gentoo in order to let a normal user to display correctly the 
sudoers commands when coming from ldap?

Many thanks in advance
