Login issue with ASP.NET MVC app

[mohitlwcc]

Hi,

I have integrated okta hosted login method with my app. The issue I am facing is as follows:

1) It allow only login for one time after that I have to reset IIS services to get it to work again. 2) Once logged in successfully, if I logout of the application, and keep browser open, and try to log back in then it goes to endless loop, and then I get "HTTP Error 400. The size of the request headers is too long.", now if I do reset IIS then it works again for one time then same problem occur again.

Below are the settings in startup.cs as well as web config:

Startup.cs:

public void Configuration(IAppBuilder app) { app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);

        app.UseCookieAuthentication(new CookieAuthenticationOptions());

        app.UseOktaMvc(new OktaMvcOptions()
        {
            OktaDomain = ConfigurationManager.AppSettings["okta:OktaDomain"],
            ClientId = ConfigurationManager.AppSettings["okta:ClientId"],
            ClientSecret = ConfigurationManager.AppSettings["okta:ClientSecret"],
            AuthorizationServerId = ConfigurationManager.AppSettings["okta:AuthorizationServerId"],
            RedirectUri = ConfigurationManager.AppSettings["okta:RedirectUri"],
            PostLogoutRedirectUri = ConfigurationManager.AppSettings["okta:PostLogoutRedirectUri"],
            GetClaimsFromUserInfoEndpoint = true,
            Scope = new List<string> { "openid", "profile", "email" },
        });
    }

Web.config

<add key="okta:ClientId" value="SOMEID" />
<add key="okta:ClientSecret" value="SOMEKEY" />
<add key="okta:OktaDomain" value="URL" />
<add key="okta:AuthorizationServerId" value="default" />

<!-- 2. Update the Okta application with these values authorization-code/callback-->
<add key="okta:RedirectUri" value="http://localhost:49922/Signin/Interactive" />
<add key="okta:PostLogoutRedirectUri" value="http://localhost:49922/Account/PostLogout" />

@mohitlwcc Thanks for reaching out! Please advise which sample you are working with.

We will need to investigate more deeply to reproduce the issue so we can provide a fix or workaround.

@mohitlwcc I've opened an internal issue to investigate further, this will need to be prioritized with other work.

Resolved by adding below line of code in Global.asax.cs file

protected void Session_Start(object sender, EventArgs e) { // place holder to solve endless loop issue }
