PPP connections with an iSeries™ server support several options for authenticating both remote clients dialing in to the iSeries, and connections to an ISP or other server that the iSeries is dialing.
The iSeries supports several methods for maintaining authentication information, ranging from simple validation lists on the iSeries that contain lists of authorized users and associated passwords, to support for RADIUS servers that maintain detailed authentication information for your network users. The iSeries also supports several options for encrypting user ID and password information, ranging from a simple password exchange to maceration support with CHAP-MD5. You can specify your preferences for system authentication, including a user ID and password used to validate the iSeries when dialing out, on the Authentication tab of the connection profile in iSeries Navigator.
