Enable SSSD on client install
    
    authconfig component changed its behavior. It no longer starts and
    enables SSSD daemon when --enablesssd and --enablesssdauth options
    are used. It only enables the PAM module and adds SSSD to nsswitch.
    
    Enable SSSD on new client/server installs manually. Also make sure
    that we stop&disable SSSD when we delete the configuration.
