Hello,

We are switching our CMS project from MultiplexingMembershipProvider (Windows and SQL) to OpenId Connect (Azure AD) using documentation provided at: https://world.episerver.com/documentation/developer-guides/CMS/security/integrate-azure-ad-using-openid-connect/

Authentication is working but when I attempt to access editor (or admin) interface, I get an ArgumentNullException.

Value cannot be null.
Parameter name: userName

EPiServer.Shell.Profile.ProfileRepository.GetOrCreateProfile(String userName)

I have pasted the relevant area of web.config, a list of the claims I'm getting, my packages, and the details of the exception below. Any assistance would be greatly appreciated.

Hi Jonathan

It looks like the user name is not properly mapped when the user returns from Azure AD. By default the OpenIDConnect library expects a claim type with a long key ("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name"), while your Azure AD setup returns one with a shorter one ("name").

Try adding the following piece of code to your OpenIdConnectAuthenticationOptions instance.

TokenValidationParameters = new TokenValidationParameters
{
    NameClaimType = "name" // Or "preferred_username",
    RoleClaimType = ClaimTypes.Role
}

Thank you for your quick response.  That was the issue.  Is there any documentation for how EPi matches profile properties to claims?  Thank you.
Stefan Holm Olsen - Dec 05, 2020 19:36
Happy to hear it fixed your issue.
I don't think Episerver keeps documentation about these claims. It is a Microsoft thing, which may be affected by the Azure AD configuration or a difference between v1 and v2 of the Authority URL.
