1. Will authentication include the release of attributes to your application?
   1. If yes, UH Data Governance guidelines apply.  For each unique application you must submit a separate request.  What that means is that you cannot register a single URL and host multiple applications under it.  
2. Is your application hosted on a non-UH server?
   1. If yes, your request may be subject to the UH Data Sharing Request process. Please send an inquiry to datagov@hawaii.edu or call (808) 956-7487.

• url (DISABLED)

  Note

  Although Aperero's CAS protocol documentation describes the use the the url parameter, the Aperero developers have disabled it in recent versions of CAS to prevent potential abuse. Their explanation of the situation may be found in this thread from the cas-users mailing list. The url parameter defined in the former CAS 2.0 specification is not a valid parameter in CAS 3.0 anymore. CAS Servers MUST ignore given url parameters.

  
  

Examples

• To logout a user and prevent her from automatically logging back into a Web application, the Web application can forward the user to the Logout URL of UH Login. That URL will destroy the ticket-granting cookie that enables the single sign-on feature and gives the user a page that informs them that they have logged out of UH Login.

  No Format
  https://$WEBLOGIN-HOST/cas/logout

  
  

• To logout a user and prevent her from automatically logging back into a Web application, the Web application can forward the user to the Logout URL of UH Login. That URL will destroy the ticket-granting cookie that enables the single sign-on feature and redirect the user to the URL identified by the service parameter.

  No Format
  https://$WEBLOGIN-HOST/cas/logout?service=https://myserver/myapp

  
  

  Info
  The URL provided by the service parameter must be registered to use UH Login.

A future enhancement could make single sign-on an option for the user so the default will be no single sign-on. If the user chooses to enable single sign-on when authenticating to UH Login, only those apps that don't use the renew parameter will permit single sign-on if the user doesn't logout via the Logout URL from a previously visited app.
