To Whom It May Concern,
I have setup a new ADFS 3.0 dev environment and added a relying party trust for a vendor we are working with. The relying party has been configured and the proper claims are provided. However, when we attempt to authenticate the service providers software is providing an error once I hit sign in on the ADFS page that states :
Controller: saml20
Action: Index
Exception: The property 'SpClaimType' cannot be set to a null value.
Everything looks to be setup correctly, so I cant figure out whether this is an issue caused by our identity provider or from the service provider. Any feedback is greatly appreciated. I've exchanged several emails with the vendor and I had to create a transform rule for the NAME ID which I had missing. After doing this i'm still receiving the same error, I'm going to circle back with the application vendor on Monday. Just wanted to see if someone out there may have run into this issue and what the end result was.
Thank You in advance.
