The Sponsored Guest Portal allows guest users to access the network using credentials that have been created and managed by a sponsor. By configuring RSA Cloud Access Service (CAS) as the authentication provider, guest users can authenticate through RSA before accessing the Sponsored Guest Portal.

Procedure

1. Navigate to Work Centers > Guest Access > Portals & Components.
   
2. In the left pane, click Guest Portals > Sponsored Guest Portal.
3. Under Portal Behavior and Flow Settings, expand Portal Settings. 
4. In the Authentication method drop-down list, choose the RSA External Identity Source that was created earlier.
   Note: A new Identity Source Entity should be created separately, specifically for the Sponsored Guest Portal.
