Description of problem:
When running the ipa-client-install test suite, sssd_be crashed. In matching timestamps, the test that was running at the time was to install client using preserve-sssd, and the uninstall of this client may have caused it. But wasn't able to replicate the crash again

Pavel took a look, and suggested it might be related to 
https://fedorahosted.org/sssd/ticket/1751

Version-Release number of selected component (if applicable):
sssd-1.9.2-128

How reproducible:
saw it once

Steps to Reproduce:
listed below in "additional info"


Actual results:
sssd_be crashed

Expected results:
no crash

Additional info:
The goal of the test is to install client using the option --preserve-sssd, and verify the install didn't overwrite it.

the steps are:
