-DNS Reverse lookups are not used for determining the

-retrieve the server name to use in GSAPI authentication.
+.B \-D
+The server name passed to GSSAPI for authentication is normally the
+name exactly as requested.  e.g. for NFS
+it is the server name in the "servername:/path" mount request.  Only if this
+servername appears to be an IP address (IPv4 or IPv6) or an
+unqualified name (no dots) will a reverse DNS lookup
+will be performed to get the canoncial server name.
+
+If
+.B \-D
+is present, a reverse DNS lookup will
+.I always
+be used, even if the server name looks like a canonical name.  So it
+is needed if partially qualified, or non canonical names are regularly
+used.
+
+Using
+.B \-D
+can introduce a security vulnerability, so it is recommended that
+.B \-D
+not be used, and that canonical names always be used when requesting
