# NETID_AUTHORITATIVE
-# If set to TRUE the initgroups() function will accept the information
+# If set to TRUE, the initgroups() function will accept the information
# from the netid.byname NIS map as authoritative. This can speed up the
# function significantly if the group.byname map is large. The content
# of the netid.byname map is used AS IS. The system administrator has

+# SERVICES_AUTHORITATIVE
+# If set to TRUE, the getservbyname{,_r}() function will assume

+# primary service names and service aliases. The system administrator
