sssd and abrt logs

Description of problem:
When joined to domain in one part of the forest, segfaults are observed when
querying users from a different tree in the forest. This users are still
resolved.

Version-Release number of selected component (if applicable):
Using version:
sssd-1.11.2-65.el7

How reproducible:
intermittent

Steps to Reproduce:
Using our stock QE AD forest layout:
Primary: sssdad.com
Child: child1.sssdad.com
Second tree: sssdad_tree.com

testing phase ad_other_dc_01 joins the child domain under the root domain. This
test phase checks to make sure users for the root domain and the child resolve.

The ad_other_dc_02 phase of the automation checks to make sure users for the
second tree are resolved. The users properly resolve and this test phase
happens at Wed Apr 23 16:07:12 EDT 2014 in the logs.  A segfault is observed
after this in dmesg and message log.

00007ffad03655e8 sp 00007fffd0c4b340 error 4 in
libsss_ad.so[7ffad0339000+38000]

The phase ad_other_dc_03 joins the second tree domain and make sure users for
the root domain and the second tree domain users resolve.

The ad_other_dc_04 phase of the automation checks to make sure users for the
child domain resolve. These users properly resolve and this test phase happens
at Wed Apr 23 16:07:45 EDT 2014 in the logs. A segfault is observed after this
in dmesg and message log.
