Description of problem:
During hbacrule-add-host, adding canonical names e.g. "scroponok" resolves them to "scroponok.lab.eng.pnq.redhat.com", however, during ipa hbactest, entering "scroponok" doesn't work. I had to enter "scroponok.lab.eng.pnq.redhat.com" explicitly.

Version-Release number of selected component (if applicable):
ipa-server-2.1.1-4.el6.x86_64

How reproducible:
Always

Steps to Reproduce:
1. [root@kungfupanda ~]# ipa hbacrule-add-host 
Rule name: rule1
[member host]: cavenger
[member host group]: 
  Rule name: rule1
  Enabled: TRUE
  Hosts: cavenger.lab.eng.pnq.redhat.com
-------------------------
Number of members added 1
-------------------------

2.[root@kungfupanda ~]# ipa hbactest
User name: kaushik
Source host: scroponok.lab.eng.pnq.redhat.com
Target host: cavenger.lab.eng.pnq.redhat.com
Service: sshd
--------------------
Access granted: True
--------------------

3. # ipa hbactest
User name: kaushik
Source host: scroponok
Target host: cavenger
Service: sshd
---------------------
Access granted: False
---------------------


Actual results: Does not resolve the canonical name and displays "Access granted: False"

Expected results: Should resolve canonical name and display "Access granted: True" as it does while entering the complete fqdn.
