Configuring RADIUS Authentication
RADIUS Authentication authenticates sponsor users to the Guest Server using their existing RADIUS
user accounts. This keeps sponsors from having to remember another set of user names and passwords
just to authenticate to the Guest Server. It also enables the administrator to quickly roll out Guest Access

• Add a RADIUS Server
• Edit an Existing RADIUS Server
• Delete an Existing RADIUS Server Entry
