Hi All,

  We are having an issue performing RHEL 6.6 to 6.7 upgrade with SSSD.  The
systems are already enrolled and working in IPA 3.0.0-50 using 6.6 client.
We yum update and sssd gives this
                                                              
 Non-fatal POSTTRANS scriptlet failure in rpm package         
 sssd-1.12.4-47.el6_7.8.ppc64                                 
 warning: %posttrans(sssd-1.12.4-47.el6_7.8.ppc64) scriptlet  
 failed, exit status 1                                        
                                                              



Seems to install however sssd will no longer start.  I can run ldap
searches against the IPA server and kinit without issue
I have un-enrolled the client and re-enrolled to no avail... once enroll
gets to starting sssd it says sssd restart failed and continues to enroll.
I have reinstalled sssd, ipa client and c-ares, I have removed the sssd
cache db.

The really strange part is if we wait approx 24 hours sssd starts working
again which we have reproduced on 2 servers we are testing with... are we
missing some sort of lease or cache?  Using this to remove the sssd db
rm -rf /var/lib/sss/db/*



Here is a piece of the gdb core dump

Any help is appreciated as I have spent a good 15 hours reading the logs
and bug reports and not any closer to a resolution.
