We have a non-domino portal and there we place links to applications hosted on our Domino server. Single Sign on (based on session authentication) is working between the portal and Domino so when users follow the link they are immediately in the domino application. BUT when they are not authorized for the Domino application then they are confronted with the Domino login form, this is very confusing for them, they start trying every username and password they know but of course without success.
In this situation instead of the login form I would like to present a page explaining that they do not have access to the application and preferable with on it a link to a seperate page that explains the application with also the contact person for the application on it. We already have a catalog with these info pages available.
How can we do this ?
