SAML2 setup on IIS not working?

Product: PowerShell Universal
Version: 3.4.1

Currently i have Windows auth setup on IIS working well with AD group claims setup using the schema.

I am now wanting to setup SAML2. Iv added the following for the setup i have blanked (XX) this out for security.

Entity ID: xx
Identity Provider Entity ID: xx
Metadata Address: xx
Return URL: xx

I have restarted IIS but it still uses the Windows auth. I assume i need to make other config changes to make it auth via SAML2?


Further to add, i have it going to my IDP but after auth i now get Unauthorized Access.

I assume its not mapping something correctly? I believe its mapping the username.

Happy to provide SAML tracer logs
