Dear freeIPA gurus,
in previous thread (
https://www.redhat.com/archives/freeipa-users/2016-July/msg00046.html) you
helped me make sudo working for AD users on Centos 7.0 (
spcss-2t-www.linuxdomain.cz).
It was caused by not knowing sudo needs to be enabled in HBAC rules.
Now it works properly on Centos 7.0 client.
But it does not work on Centos 6.5 (zp-cml-test.linuxdomain.cz) with the
same sssd.conf setup.
Error message is always:

[simecek.to...@sd-stc.cz@zp-cml-test ~]$ sudo cat /etc/nsswitch.conf
[sudo] password for simecek.to...@sd-stc.cz:
simecek.to...@sd-stc.cz is not allowed to run sudo on zp-cml-test.  This
incident will be reported.

Here are my HBAC rules, the second one should apply. It definitely applies
for Centos 7.0 server:
[root@svlxxipap ~]# ipa hbacrule-find
--------------------
2 HBAC rules matched
--------------------
  Rule name: allow_all
  User category: all
  Host category: all
  Service category: all
  Description: Allow all users to access any host from any host
  Enabled: FALSE

  Rule name: Unixari na test servery
  Enabled: TRUE
  User Groups: grpunixadmins
  Hosts: spcss-2t-www.linuxdomain.cz, zp-cml-test.linuxdomain.cz
  Services: login, sshd, sudo, sudo-i, su, su-l
----------------------------
Number of entries returned 2
----------------------------

This is my /etc/sssd/sssd.conf. It the same like on Centos 7.0 server, just
with proper server name of course:

[root@zp-cml-test sssd]# cat /etc/sssd/sssd.conf

It looks like it cannot get any rules from IPA server. Any idea why? It
works fine on Centos 7.0 client.

Thanks
