ID3206 Exception

If you install AVEVA Information Standards Manager as an application under existing site:

http://<hostname>/aveva-ism

you will need to access it with a URL containing a trailing slash:

http://<hostname>/aveva-ism/

If your user is not authenticated and you do not use the trailing slash, you will get the following exception:

ID3206: A SignInResponse message may only redirect within the current web application: '/aveva-ism' is not allowed.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: Microsoft.IdentityModel.Protocols.FederationException: ID3206: A SignInResponse message may only redirect within the current web application: '/aveva-ism' is not allowed.

This is a weakness in Windows Identity Framework (WIF). There are currently no workarounds for this issue.
