Digest Authentication Schemes

A digest authentication scheme reads an encrypted user attribute string stored in a directory, then compares the string to the encrypted string it receives from the user. If the encrypted strings match, the Policy Server authenticates the user. A digest scheme compares a string encrypted on a client workstation to an encrypted string on a server without using an encrypted transmission.

SiteMinder supports the following digest authentication schemes:

• RADIUS CHAP
• RADIUS PAP
