c# - Update claims in ClaimsPrincipal -

i using adal azure active directory , need add claims via custom owinmiddleware. when add claims principal, able access them in current request. after page refresh, claim gone.

i thought owin handled serialization of claims , put cookie itself, doesn't seem case.

i add claims 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 persist new claims cookie?

i've added claims wrong identity. had added identity variable instead of 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});
