Update claims in ClaimsPrincipal

Question

I am using Adal with Azure Active Directory and I need to add extra claims via custom OwinMiddleware. When I add claims to this principal, I am able to access them in the current request. But after a page refresh, the claim is gone.

I thought Owin handled serialization of claims and put it into a cookie itself, but this doesn't seem to be the case.

I add the claims as follows:

 var claimsIdentity = (ClaimsIdentity) ClaimsPrincipal.Current.Identity;
        if (!claimsIdentity.IsAuthenticated) return;

        var identity = new ClaimsIdentity(claimsIdentity);

        var currentTenantClaim = GetTenantClaim();

        if (currentTenantClaim != null)
            claimsIdentity.RemoveClaim(currentTenantClaim);

        claimsIdentity.AddClaim(new Claim(ClaimTypes.CurrentTenantId, id));

        context.Authentication.AuthenticationResponseGrant = new AuthenticationResponseGrant
            (new ClaimsPrincipal(identity), new AuthenticationProperties {IsPersistent = true});

Any ideas on how to persist the new claims to the cookie?

Solution

I've added the claims to the wrong Identity. They had to be added to the identity variable instead of the claimsIdentity.

Working code:

        var claimsIdentity = (ClaimsIdentity) context.Authentication.User.Identity;
        if (!claimsIdentity.IsAuthenticated) return;

        var identity = new ClaimsIdentity(claimsIdentity);

        var currentTenantClaim = GetTenantClaim(identity);

        if (currentTenantClaim != null)
            identity.RemoveClaim(currentTenantClaim);

        identity.AddClaim(new Claim(ClaimTypes.CurrentTenantId, id));

        context.Authentication.AuthenticationResponseGrant = new AuthenticationResponseGrant
            (new ClaimsPrincipal(identity), new AuthenticationProperties {IsPersistent = true});

This is what I exactly need to do. Can you please share your complete code? Thanks

What type is the context object (first line of your code sample)?
