c# - Automatically login local user after registration with IdentityServer3 -

using identityserver3 need automatically login , redirect local user client application after user has completed registration process. there elegant way this? digging suspect not, in case there hack can use achieve this?

i able achieve external users using custom user service, utilized partial login. however, local users aren't in authentication process handled user service until login username , password.

please note don't have access users password registration process covered multiple screens / views in instance required verify email part of registration process.

progress:

i've found https://github.com/identityserver/identityserver3/issues/563 haven't worked out how trigger redirect.

i'm attempting issue authentication token using:

var localauthresult = userservice.authenticatelocalasync(user); request.getowincontext().authentication.signin(new claimsidentity(localauthresult.result.user.claims, thinktecture.identityserver.core.constants.primaryauthenticationtype)); 

but best can far redirect user login screen:

httpcookie cookie = request.cookies["signin"]; // stored @ beginning of registration process return redirect("~/core/login?signin=" + cookie.value); 

add registration link login page using loginpagelinks:

var authoptions = new thinktecture.identityserver.core.configuration.authenticationoptions {     identityproviders = configureidentityproviders,     enablelocallogin = true,     enablepostsignoutautoredirect = true,     loginpagelinks = new loginpagelink[] {          new loginpagelink{             text = "register",             href = "register"         }     } }; 

using loginpagelinks result in signin url parameter added end of url on login page. needs preserved if registration process spans multiple pages. easy store value in cookie.

a gotcha registration page must exist under same url identity server, e.g. "core". allow pages share cookies identity server. in standard mvc controllers can achieved using route decorator:

[route("core/register")] [httpget] [allowanonymous] public actionresult register(string signin) {     response.cookies.add(new httpcookie("signin", signin)); // preserve signin can use automatically redirect user after registration process     return view(new registerviewmodel()); } 

once registration process has been completed can use issuelogincookie extension method create login cookie. signin url parameter can used getsigninmessage extension method retrive returnurl redirect response automatically login user , return them client application:

using thinktecture.identityserver.core.extensions; using thinktecture.identityserver.core.models;  ...  authenticatedlogin login = new authenticatedlogin()     {            identityprovider = thinktecture.identityserver.core.constants.builtinidentityprovider,         subject = userid,         name = authobjects.authuserservice.getdisplaynameforaccount(userid)       }; request.getowincontext().environment.issuelogincookie(login);  httpcookie cookie = request.cookies["signin"]; if (cookie != null) {     signinmessage message = request.getowincontext().environment.getsigninmessage(cookie.value);     return redirect(message.returnurl); } else  ...
