I'm setting up my first Shibboleth 3.x app running under IIS (Windows Server 2019), and have run into a roadblock. It's a vendor's app, and not something I coded myself.
I've currently got things configured so that users can authenticate and log in successfully. However, if they use anything other than the specific URL to the login page, it fails with a 500 code. So I feel like I'm missing something in my shibboleth2.xml file.
This URL works and the user can manually interact with the items in the web app after authenticating: https://Application/Login.aspx
This URL fails after the user authenticates and gets redirected back to the web app: https://Application/WMR.aspx?APGuid=E56AE53FB786466DD090D67D3B407C2C&PrevPage=Main.aspx
(the second URL comes out of an email that gets generated for a user by the web app)
Anyone see this behavior before, and can point me towards a solution?
Thanks!
