+line. There is no restriction on using the \fIfile\fR or \fIcall\fR
+options within an options file.
+.SH PRIVILEGED OPTIONS
+As indicated above, some security-sensitive options are privileged,
+which means that they may not be used by an ordinary non-privileged
+user running a setuid-root pppd, either on the command line, in the
+user's ~/.ppprc file, or in an options file read using the \fIfile\fR
+option. Privileged options may be used in /etc/ppp/options file or in
+an options file read using the \fIcall\fR option. If pppd is being
+run by the root user, privileged options can be used without
+restriction.
+.PP
+The normal way that pppd should be set up is to have the \fIauth\fR
+option in the /etc/ppp/options file. (This may become the default in
+later releases.) If users wish to use pppd to dial out to a peer
+which will refuse to authenticate itself (such as an internet service
+provider), the system administrator should create an options file
+under /etc/ppp/peers containing the \fInoauth\fR option, the name of
+the serial port to use, and the \fIconnect\fR option (if required),
+plus any other appropriate options. In this way, pppd can be set up
+to allow non-privileged users to make unauthenticated connections only
+to trusted peers.
