How do I redirect a user back to a specific end user page or form after SSO authentication?  

Environment: 

Customer Portal Single Sign-On

Resolution:

By default, customer portal does not process the relay state or support deep linking.  If you want to redirect the user to a specific page after authentication you have two options;

• Pass the redirect in the ACS URL.  By default, the user will be directed to the Home page after authentication.  You can specify a different page to direct the user after authentication.  Please see How You Redirect Contacts After Login.
• The other option is to create a pre_login hook to intercept the SAML response and parse out the relay state
