[Freeipa-users] Managing Sudo through FreeIPA

[William Muriithi]

Hello

I have been trying to setup user access through sudo file managed by
FreeIPA and it don't seem to be working.  I am not sure how to go
about fixing it, but I guess the best place to start is ask what I
should expect the IPA installation script should set up and what
should be done manually

[root at demo2 wmuriithi]# rpm -qa | grep sssd
sssd-client-1.8.0-32.el6.x86_64
sssd-1.8.0-32.el6.x86_64
[root at demo2 wmuriithi]#



[root at demo2 wmuriithi]# rpm -qa | grep sudo
sudo-1.7.4p5-13.el6_3.x86_64

The only errors related to sudo that I can find is on apache error logs

I created the user as below and associated it with a group, which I
then allowed to use less for reading file.  As you can see below, it
seem to does not work.

Nov  7 16:05:42 demo2 sudo: pam_sss(sudo:auth): authentication
success; logname=williamm uid=0 euid=0 tty=/dev/pts/2 ruser=williamm
rhost= user=williamm
Nov  7 16:05:43 demo2 sudo: williamm : user NOT in sudoers ; TTY=pts/2
; PWD=/home/wmuriithi ; USER=root ; COMMAND=/usr/bin/less
/var/log/secure


- My question is, does the client install script take care of sudo
configuration or is that done manually?  I don't see any sudo related
flag on the client installation script.

- I have tried configuring sssd for sudo use and it didn't go well.
Last time I messed around with LDAP managed sudo, I have to install a
LDAP capable sudo package.  The ipa-client install did not install
this package. Does IPA sudo management work differently?

- Where would I check for logs?  I checked sssd logs and they are empty.

- I am missing the basedn configuration on  sssd configuration.  From
this bug, it should have been setup by installer, oddly though it was
not setup and the bug is closed. I attempted to fix it by adding the
line below but it make sudo completely unusable.  It could not find
any valid users apparently

ldap_netgroup_search_base = cn=ng,cn=compat,dc=example,dc=loc

Nov  7 16:05:42 demo2 sudo: pam_sss(sudo:auth): authentication
success; logname=williamm uid=0 euid=0 tty=/dev/pts/2 ruser=williamm
rhost= user=williamm
Nov  7 16:05:43 demo2 sudo: williamm : user NOT in sudoers ; TTY=pts/2
; PWD=/home/wmuriithi ; USER=root ; COMMAND=/usr/bin/less
/var/log/secure


Any pointers on why we are going?

Thank you a lot in advance.
