Info

Password Authentication Protocol All versions of pppd support the Password Authentication Protocol (PAP). PAP sends the password(s) across the connection in clear text. Since the password exists in the clear, the standard authenitcation mechanisms can be used to verify the remote user. Simply specify the login parameter in the appropriate ppp options file. All remote users authorized to use pppd for access must be listed in the pap-secrets file (usually found in /etc/ppp). But if authentication is being passed off to the underlying system their password field in pap-secrets should simply be set to a pair of double quotes. See the section on P<strong>AM</strong> for information on configuring the underlying system to authenticate users against the DSA.
Challenge Host Authentication Protocol The PAP methods transmission of the password in clear text posses significant security issues. Fortunately pppd also supports the Challenge Host Authentication Protocol (CHAP) which does not suffer from this weakness. However, with CHAP the pppd process never acquires an unencrypted copy of the users password, breaking the ability to use underlying authentication mechanisms such as P<strong>AM</strong>. This leaves the administator having to maintain user passwords in the chap-secrets file (usually found in /etc/ppp/).
