Does it really fix the whole ticket?

There is also in freeipa.spec.in %post client (i.e. upgrade):

             cat /etc/krb5.conf >> /etc/krb5.conf.ipanew
             mv /etc/krb5.conf.ipanew /etc/krb5.conf
             /sbin/restorecon /etc/krb5.conf

+ some others.

Between the mv and restorecon, SSSD tries to access the file and raises AVC.

In this case we can freely use mv -z since target platforms are Fedora 
and newest RHEL.
