IDX21329: RequireState is 'True' but the OpenIdConnectProtocolValidationContext.State is null. State cannot be validated.

Hi,

I have same issue which was reported 4 years ago. Here is the issue 385. I think the issue is not resolved, but it was closed.

Same issue was reported few times but for newer ASPNETCORE version: 516, 52400

Expected Behavior After enabling RequireState and RequireStateValidation, any state set in context.ProtocolMessage.State should be validated automatically.

Steps To Reproduce When configuring OpenIdConnect, I am enabling both RequireState and RequireStateValidation:

options.ProtocolValidator.RequireState = true; options.ProtocolValidator.RequireStateValidation = true;

This will result in the following exception: IDX21329: RequireState is 'True' but the OpenIdConnectProtocolValidationContext.State is null. State cannot be validated.

When looking into where this is created, it seems that State is never set on this context: https://github.com/aspnet/AspNetKatana/blob/43996b47015ca0c0ad12cdb6c87a017534eec620/src/Microsoft.Owin.Security.OpenIdConnect/OpenidConnectAuthenticationHandler.cs#L390

Exception details:

IDX21329: RequireState is 'True' but the OpenIdConnectProtocolValidationContext.State is null. State cannot be validated.
