Description of problem:
No crash detected when it is set to false which is the default and
authentication is successful as expected ([ipa_hbac_evaluate_rules] (0x0080):
Access granted by HBAC rule [rule1]) since srchost is set to ALL
([hbac_shost_attrs_to_rule] (0x2000): Source hosts disabled, setting ALL).
However, if you set this value to true, authentication hangs and sssd crash
detected.

Version-Release number of selected component (if applicable):
sssd-1.8.0-4.el6.beta3.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Configure ipa hbac rule as:
[root@rodimus ~]# ipa hbacrule-find
--------------------
2 HBAC rules matched
--------------------
  Rule name: allow_all
  User category: all
  Host category: all
  Source host category: all
  Service category: all
  Description: Allow all users to access any host from any host
  Enabled: FALSE

  Rule name: rule1
  Enabled: TRUE
  Users: shanks
  Hosts: primenova.lab.eng.pnq.redhat.com
  Source Hosts: bumblebee.lab.eng.pnq.redhat.com
  Services: sshd
----------------------------
Number of entries returned 2
----------------------------
[root@rodimus ~]#


2. # hostname
primenova.lab.eng.pnq.redhat.com

3. Configure sssd.conf as:
[root@primenova ~]# egrep -v ^# /etc/sssd/sssd.conf
[domain/lab.eng.pnq.redhat.com]
debug_level = 9
cache_credentials = True
krb5_store_password_if_offline = True
ipa_domain = lab.eng.pnq.redhat.com
id_provider = ipa
auth_provider = ipa
access_provider = ipa
chpass_provider = ipa
ipa_server = _srv_, rodimus.lab.eng.pnq.redhat.com
ldap_tls_cacert = /etc/ipa/ca.crt
ipa_hbac_support_srchost = True
[sssd]
config_file_version = 2
services = nss, pam

domains = lab.eng.pnq.redhat.com
[nss]

[pam]


[root@primenova ~]#

4. [root@primenova ~]# ssh -l shanks $HOSTNAME
shanks@primenova.lab.eng.pnq.redhat.com's password:
<hangs>
