my code:
protected void LogIn(object sender, EventArgs e)
{
string url="";
if (IsValid)
{
// Convalidare la password utente
var manager = Context.GetOwinContext().GetUserManager<ApplicationUserManager>();
var signinManager = Context.GetOwinContext().GetUserManager<ApplicationSignInManager>();
var result = signinManager.PasswordSignIn(Email.Text, Password.Text, RememberMe.Checked, shouldLockout: false);
FormsAuthentication.RedirectFromLoginPage(User.Identity.GetUserId(), false);
var roles = manager.GetRoles(User.Identity.GetUserId().ToString());
Session["Role"] = roles[0];
switch (Convert.ToString(Session["Role"]))
{
case "GruppoAzienda":
url = "G_Aziende/g_aziende.aspx";break;
case "Azienda":
url = "Aziende/Dipendenti.aspx"; break;
}
switch (result)
{
case SignInStatus.Success:
IdentityHelper.RedirectToReturnUrl(Request.QueryString["ReturnUrl"], Response, url);
break;
case SignInStatus.LockedOut:
Response.Redirect("/Account/Lockout");
break;
case SignInStatus.RequiresVerification:
Response.Redirect(String.Format("/Account/TwoFactorAuthenticationSignIn?ReturnUrl={0}&RememberMe={1}",
Request.QueryString["ReturnUrl"],
RememberMe.Checked),
true);
break;
case SignInStatus.Failure:
default:
FailureText.Text = "Tentativo di accesso non valido";
ErrorMessage.Visible = true;
break;
}
}
}
this is logout code:
protected void Unnamed_LoggingOut(object sender, LoginCancelEventArgs e)
{
Context.GetOwinContext().Authentication.SignOut(DefaultAuthenticationTypes.ApplicationCookie);
Session.Abandon();
}
Can someone help?

Retrieving claim value for current logged in user

I have an ASP.Net web form application that users can register to. In the registration process, some user details are stored as claims, the MemberApproved variable is used to check the approval status of a user, it is set to "No" when the user is created, and can be changed later by admin:
var manager = Context.GetOwinContext().GetUserManager<ApplicationUserManager>();
var signInManager = Context.GetOwinContext().Get<ApplicationSignInManager>();
var user = new ApplicationUser() { UserName = Email.Text, Email = Email.Text, FirstName = FirstName.Text, LastName = LastName.Text,MemberApproved="No" };
THis is working fine and I can see the user details above added correctly in the AspNetUsers
Then I am trying to check if the user has been approved by an admin when they login, in this process, I am trying to retrieve MemberApproved value using the following code:
protected void Page_Load(object sender, EventArgs e)
{
RegisterHyperLink.NavigateUrl = "Register";
OpenAuthLogin.ReturnUrl = Request.QueryString["ReturnUrl"];
var returnUrl = HttpUtility.UrlEncode(Request.QueryString["ReturnUrl"]);
if (!String.IsNullOrEmpty(returnUrl))
{
RegisterHyperLink.NavigateUrl += "?ReturnUrl=" + returnUrl;
}
}
protected void LogIn(object sender, EventArgs e)
{
if (IsValid)
{
var manager = Context.GetOwinContext().GetUserManager<ApplicationUserManager>();
var signinManager = Context.GetOwinContext().GetUserManager<ApplicationSignInManager>();
var result = signinManager.PasswordSignIn(Email.Text, Password.Text, RememberMe.Checked, shouldLockout: false);
switch (result)
{
case SignInStatus.Success:
var claims = ClaimsPrincipal.Current.Identities.First().Claims.ToList();
string MemberApproved = claims?.FirstOrDefault(x => x.Type.Equals("MemberApproved", StringComparison.OrdinalIgnoreCase))?.Value;
if (MemberApproved == "No")
{
FailureText.Text = "User not approved yet";
ErrorMessage.Visible = true;
break;
}
else
{ IdentityHelper.RedirectToReturnUrl(Request.QueryString["ReturnUrl"], Response);
break;
}
case SignInStatus.LockedOut:
Response.Redirect("/Account/Lockout");
break;
case SignInStatus.RequiresVerification:
Response.Redirect(String.Format("/Account/TwoFactorAuthenticationSignIn?ReturnUrl={0}&RememberMe={1}",
Request.QueryString["ReturnUrl"],
RememberMe.Checked),
true);
break;
case SignInStatus.Failure:
default:
FailureText.Text = "Invalid login attempt";
ErrorMessage.Visible = true;
break;
}
}
}
}
I am however running into problems and the code above does not seem to be able to retrieve the value of "MemberApproved"
Any suggestions would be very much appreciated.

HttpModule Web Api

I'm trying to get an auth basic on my web api. I've written a simple HttpModule to check it
public class BasicAuth : IHttpModule
{
SqlConnection con = new SqlConnection(WebConfigurationManager.ConnectionStrings["Connection"].ConnectionString);
private const string Realm = "MyRealm";
public void Init(HttpApplication context)
{
// Register event handlers
context.AuthorizeRequest += new EventHandler(OnApplicationAuthenticateRequest);
context.EndRequest += new EventHandler(OnApplicationEndRequest);
}
private static void SetPrincipal(IPrincipal principal)
{
Thread.CurrentPrincipal = principal;
if (HttpContext.Current != null)
{
HttpContext.Current.User = principal;
}
}
private bool CheckPassword(string username, string password)
{
var parameters = new DynamicParameters();
parameters.Add("#UserName", username);
parameters.Add("#Password", password);
con.Open();
try
{
var query = //query to db to check username and password
return query.Count() == 1 ? true : false;
}
catch
{
return false;
}
finally
{
con.Close();
}
}
private bool AuthenticateUser(string credentials)
{
try
{
var encoding = Encoding.GetEncoding("iso-8859-1");
credentials = encoding.GetString(Convert.FromBase64String(credentials));
int separator = credentials.IndexOf(':');
string name = credentials.Substring(0, separator);
string password = credentials.Substring(separator + 1);
if (CheckPassword(name, password))
{
var identity = new GenericIdentity(name);
SetPrincipal(new GenericPrincipal(identity, null));
return true;
}
else
{
return false;
}
}
catch
{
return false;
}
}
private void OnApplicationAuthenticateRequest(object sender, EventArgs e)
{
var authHeader = request.Headers["Authorization"];
if (authHeader != null)
{
var authHeaderVal = AuthenticationHeaderValue.Parse(authHeader);
// RFC 2617 sec 1.2, "scheme" name is case-insensitive
if (authHeaderVal.Scheme.Equals("basic",
StringComparison.OrdinalIgnoreCase) &&
authHeaderVal.Parameter != null)
{
if (AuthenticateUser(authHeaderVal.Parameter))
{
//user is authenticated
}
else
{
HttpContext.Current.Response.StatusCode = 401;
}
}
else
{
HttpContext.Current.Response.StatusCode = 401;
}
}
catch
{
HttpContext.Current.Response.StatusCode = 401;
}
}
private static void OnApplicationEndRequest(object sender, EventArgs e)
{
var response = HttpContext.Current.Response;
if (response.StatusCode == 401)
{
response.Headers.Add("WWW-Authenticate",
string.Format("Basic realm=\"{0}\"", Realm));
}
}
public void Dispose()
{
}
}
well, this code works pretty well, except the fact it asks for basic auth even on controller I don't put the [Authorize] tag on. And when it occurs, it gives the right data back.
Let me explain:
My HistoryController has [Authorize] attribute, to make a POST request I have to send Header auth to get data, if I don't do it, I receive 401 status code and a custom error.
My HomeController doesn't have [Authorize] attribute, if i make a get request on my homepage, the browser popups the authentication request, but if I hit Cancel it shows my home page. (The page is sent back with 401 error, checked with fiddler).
What am I doing wrong?

How to get access token identity in asp.net webforms external login page?

else if (User.Identity.IsAuthenticated)
