Description of problem:
HBAC rules configured on a FreeIPA server can be set up to limit access to particular hosts or groups of hosts. There is a bug in SSSD that fails to properly process host-groups. The effect of this is that users cannot log into the machine unless it is specified explicitly (instead of as a member of a hostgroup) in the rule.

Version-Release number of selected component (if applicable):
sssd-1.5.1-52.el6

How reproducible:
Every time

Steps to Reproduce:
1. On the FreeIPA server, create a hostgroup and add a host to it.
2. Create an HBAC rule that allows access based on the hostgroup above (set all other features of the rule to the ALL hostcat for easy testing.
3. Disable all other rules (so only this one is active).
4. On the client host, attempt to log in with a valid FreeIPA user.
  
Actual results:
The user is denied.

Expected results:
The user is granted access.
