This function establishes that LCP Authentication should be requested and CHAP should be the protocol to request. See the PPP documentation for a description of CHAP.

Call this routine with host set to LOCAL_HOST to mandate that the remote host must authenticate itself where CHAP is the authentication protocol. If CHAP is NAKed and PAP is also configured, a new request will be sent with PAP requested.

Call this routine with host set to REMOTE_HOST to accept CHAP if it is requested by the remote host or suggest CHAP in a Configuration-Nak in response to a request from the remote host for an unknown protocol or in response to a Password Authentication Protocol (PAP) request where CHAP is not configured.

In order to set up a secret, xn_chap_add_secret needs to be called. In order to set up the local host name, xn_chap_machine_name needs to be called.
