pam services under LDAP

[bluethundr <bluethundr@gmail.com>]

Hello List


 I am attempting to setup various pam modules to consult our new LDAP
services in order to do what it needs to do. My LDAP server is FreeBSD
but the clients are CentOS...

 I have setup my /etc/pam.d sudo file on the client (for example) this
way in the attempt to accomplish this via LDAP:

 [root@VIRCENT03:~]#cat /etc/pam.d/sudo
#%PAM-1.0
auth       include	system-auth
auth       required     pam_ldap.so
account    include	system-auth
account    required     pam_ldap.so
password   include	system-auth
password   required     pam_ldap.so
session    optional	pam_keyinit.so revoke
session    required	pam_limits.so
session    required     pam_ldap.so


but even tho the user is part of the %wheel group under LDAP it is
unable to sudo to any other account (including root). If I try to sudo
this is what happens:

[bluethundr@VIRCENT03:~]#sudo bash
[sudo] password for bluethundr:
bluethundr is not in the sudoers file.  This incident will be reported.

It would appear that sudo support for ldap is compiled in:

[root@VIRCENT03:~]#ldd $(which sudo)| grep -i ldap
	libldap-2.3.so.0 => /usr/lib/libldap-2.3.so.0 (0x00552000)


This is how I setup my ldap.conf file

[root@VIRCENT03:~]#cat /etc/openldap/ldap.conf
#
# LDAP Defaults
#

# See ldap.conf(5) for details
# This file should be world readable but not world writable.

#BASE	dc=example, dc=com
#URI	ldap://ldap.example.com ldap://ldap-master.example.com:666

#SIZELIMIT	12
#TIMELIMIT	15
#DEREF		never
URI ldap://ldap.acadaca.net/
BASE dc=acadaca,dc=net
TLS_CACERTDIR /etc/openldap/cacerts
sudoers_base ou=sudoers,ou=Services,dc=acadaca,dc=net


In my openldap logs on the LDAP server there appears to be no activity
when I sudo. however in the secure logs on the client I do..

Nov  8 16:05:34 VIRCENT03 su: pam_unix(su-l:session): session opened
for user root by bluethundr(uid=500)
Nov  8 16:05:37 VIRCENT03 su: pam_unix(su-l:session): session opened
for user bluethundr by bluethundr(uid=0)
Nov  8 16:05:44 VIRCENT03 sudo: bluethundr : user NOT in sudoers ;
TTY=pts/5 ; PWD=/home/bluethundr ; USER=root ; COMMAND=/bin/bash

Conversely when I sudo via LDAP on my FreeBSD ldap server this is what I see...


Nov  8 19:44:25 LBSD2 sudo: bluethundr : TTY=pts/11 ;
PWD=/usr/home/bluethundr ; USER=root ; COMMAND=/bin/bash
Nov  8 19:44:51 LBSD2 sudo: bluethundr : TTY=pts/10 ;
PWD=/usr/home/bluethundr ; USER=root ; COMMAND=/bin/bash

Works there!

I do see other events in secure.log that appear to be pam successes
however. am i interpreting this correctly that at least part of the
system is communicating with pam on the ldap server?


thanks
