The tasks in this section explain how to implement authentication on a PPP link by using the Password Authentication Protocol (PAP). The tasks use the example that is shown in Examples of PPP Authentication Configurations to illustrate a working PAP scenario for a dial-up link. Use the instructions as the basis for implementing PAP authentication at your site.
Before you perform the next procedures, you must have done the following:
Set up and tested the dial-up link between the dial-in server and dial-out machines that belong to trusted callers
Ideally, for dial-in server authentication, obtained superuser permission for the machine where the network password database is administered, for example, in LDAP, NIS, or local files
Obtained superuser authority for the local machine, either dial-in server or dial-out machine
