 	* 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
