Restart sssd after authconfig update
    
    Recent versions of authconfig do not restart sssd if only the
    --enablesssd and --enablesssdauth options are used. To make sure sssd is
    running after ipa-server-install is run this patch add an unconditional
    restart of sssd after authconfig is run during the installation.
    
    Since there already is some logic trying to determine if sssd needs to
    be restarted or stopped if freeipa in uninstalled no changes are needed
    here.
