        * utils/svcgssd/svcgssd_proc.c: Rely on count of the number of
        groups instead of using a special guard value to identify the end
        of the list. 
+       * utils/idmapd/idmapd.c: don't allow Default domain and anon-uid
+       or -gid to be specified on command line.
+       * utils/idmapd/idmapd.c: improve error messages
