I have implemented FirebaseAuth in my .NET app, but I'm not sure if I have done so correctly. It feels like I'm using a mix of FirebaseAuth and .NET authentication using cookie based authentication.
I started by generating a firebase token by succesfully signing in the user:
FirebaseAuthProvider firebaseAuthProvider = new FirebaseAuthProvider(new FirebaseConfig("API_KEY"));
FirebaseAuthLink firebaseAuthLink = await firebaseAuthProvider.SignInWithEmailAndPasswordAsync(Input.Email, Input.Password);
var firebaseToken = firebaseAuthLink.FirebaseToken;
I then created custom claims, and called HttpContext.SignInAsync using these claims to be fully signed in according to .NET and use [Authorize] on my Razor pages:
var claims = new List<Claim>()
{
new Claim(ClaimTypes.NameIdentifier, Convert.ToString(user.LocalId)),
new Claim(ClaimTypes.Role, userInfo.Role),
new Claim("Email", user.Email),
new Claim("FirstName", userInfo.FirstName),
new Claim("LastName", userInfo.LastName),
new Claim("Address", userInfo.Address),
new Claim("FirebaseToken", firebaseToken)
};
var identity = new ClaimsIdentity(claims, CookieAuthenticationDefaults.AuthenticationScheme);
var principal = new ClaimsPrincipal(identity);
await HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, principal, new AuthenticationProperties());
I see that you can also add custom claims through FirebaseAuth, so am I doing something wrong by calling HttpContext.SignInAsync? Is there an easier way to be authenticated simply by purely using FirebaseAuth?
In a restFul API with Net 6, I must use a company-provided dll to handle authentication. The problem is that this dll is currently not working, so I must manually set this.User from System.Security.Claims.ClaimsPrincipal to simulate that I am getting those claims from the dll.
How could I do this?
I have tried to access this.User from Program.cs but I see that it is not possible.
var claims = new List<Claim>();
claims.Add(new Claim(ClaimTypes.NameIdentifier, "IdUser"));
claims.Add(new Claim(ClaimTypes.NameIdentifier, "TypeUser"));
claims.Add(new Claim(ClaimTypes.NameIdentifier, "IdRol"));
System.Web.HttpContext.Current.User = new ClaimsPrincipal(new ClaimsIdentity(claims));
System.Threading.Thread.CurrentPrincipal = System.Web.HttpContext.Current.User;
How can i add role system without identity? I need to member and admin roles.
Login code:
var claims = new List<Claim>
{
new Claim(ClaimTypes.Name, loginDTO.StrUserID)
};
var userIdentity = new ClaimsIdentity(claims, "login");
ClaimsPrincipal principal = new ClaimsPrincipal(userIdentity);
await HttpContext.SignInAsync(principal);
Startup.cs
services.AddAuthorization(opt =>
{
opt.AddPolicy("Admin", policy => policy.RequireClaim(ClaimTypes.Name));
});
How can i add role system without identity? I need to member and admin roles.
As far as I know, if you used asp.net core cookie authentication , there is no need to build a role system.
We could write the codes in your login logic to check the user role from database.
Then we could add role by adding the ClaimTypes.Role Claim. Then we could use [Authorize(Roles ="Admin")] attribute to let only admin role user access.
More details, you could refer to below codes:
//Here build the logic to get the user role from database, then create a new role claim to add the user role.
var claims = new List<Claim>
{
new Claim(ClaimTypes.Name, "TestA"),
new Claim(ClaimTypes.Role, "Admin"),
};
var userIdentity = new ClaimsIdentity(claims, "login");
ClaimsPrincipal principal = new ClaimsPrincipal(userIdentity);
HttpContext.SignInAsync(principal);
On the controller:
[Authorize(Roles ="Admin")]
public class AdminController : Controller
How do I add the new claims in such a way that they persist through requests until the cookie expires?
I am using OWIN middle ware, on-premises authentication to authenticate the users logging into the system.
The sign-in part is successful, and I added Roles to the user claims provided by the ws-federation to help authorize the user for certain action methods.
At the time of login, in the controller, I have written the following to add the roles:
string[] roles = { "Role1", "Role2" };
var identity = new ClaimsIdentity(User.Identity);
foreach (var role in roles)
{
identity.AddClaim(new Claim(ClaimTypes.Role, role));
}
var authenticationManager = HttpContext.GetOwinContext().Authentication;
authenticationManager.AuthenticationResponseGrant = new AuthenticationResponseGrant
(new ClaimsPrincipal(identity),
new AuthenticationProperties { IsPersistent = true });
But when I check the claims at the next request, I don't see the role claims.
After successful authentication I believe you added custom claims (normally to some event handler once successfully authenticated). Now in order to persist that information in subsequent request you need to use CookieAuthentication middle ware before your authentication owin in pipeline.
How it works :
Upon successful authentication first time and addition of custom claims, claims will be transformed into sort of auth cookie and sent back to client. Subsequent request will carry this auth cookie. CookieAuthentication middle ware on finding auth cookie will set your Thread.CurrentPriciple with claims obtained from cookie.
During first time request when cookie middle ware does see any auth cookie, it passes request to next middle ware in pipe line (Authentication owin in your case) to challenge user for login.
app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);
app.UseCookieAuthentication(new CookieAuthenticationOptions()
{
AuthenticationType = "Cookies",
AuthenticationMode= AuthenticationMode.Active,
CookieName="XXXXX",
CookieDomain= _cookiedomain,
/* you can go with default cookie encryption also */
TicketDataFormat = new TicketDataFormat(_x509DataProtector),
SlidingExpiration = true,
CookieSecure = CookieSecureOption.Always,
});
app.UseOpenIdConnectAuthentication(new OpenIdConnectAuthenticationOptions
{
ClientId = _clientID,
Authority = _authority,
RedirectUri = _redirectUri,
UseTokenLifetime = false,
Notifications = new OpenIdConnectAuthenticationNotifications
{
SecurityTokenValidated = SecurityTokenValidated,
AuthenticationFailed = (context) =>
{
/* your logic to handle failure*/
}
},
TokenValidationParameters = new System.IdentityModel.Tokens.TokenValidationParameters
{
ValidIssuers = _validIssuers,
ValidateIssuer = _isValidIssuers,
}
});
EDIT: (Additional information)
Pretty much the exact code as above works for ws federation also, with the same logic and everything.
SecurityTokenValidated = notification =>
{
ClaimsIdentity identity = notification.AuthenticationTicket.Identity;
string[] roles = { "Role1", "Role2" };
foreach (var role in roles)
{
identity.AddClaim(new Claim(ClaimTypes.Role, role));
}
return Task.FromResult(0);
}
You need to use the same AuthenticationType that you used in Startup.ConfigureAuth. For example:
In Startup.ConfigureAuth:
app.UseCookieAuthentication(new CookieAuthenticationOptions {
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
//....
});
And in your login code (provided in the question):
var identity = new ClaimsIdentity(DefaultAuthenticationTypes.ApplicationCookie);
Or make sure that the User.Identity has the same AuthenticationType, and you're good to use that like you did:
var identity = new ClaimsIdentity(User.Identity);
Now the important part is that for the login, you should add the claims before singing the use in, not after. Something like this:
HttpContext.GetOwinContext().Authentication.SignIn(identity);
You can add the claims after signing in, but you will be modifying the cookie right after it is created, which is not efficient. If in some other code you need to modify the claims, then you can use something similar to your code, but you must get the context from Current:
HttpContext.Current.GetOwinContext().Authentication.AuthenticationResponseGrant =
new AuthenticationResponseGrant(new ClaimsPrincipal(identity),
new AuthenticationProperties { IsPersistent = true });
So you can fix your code by simply adding Current like above, but that's not efficient for the login code and it is better to pass the claims to the SignIn function.
you can do the following in WEB API C # (SOAP),(STORED PROCEDURES)
public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
{
context.OwinContext.Response.Headers.Add("Access-Control-Allow-Origin", new[] { "*" });
LoginModel model = new LoginModel();
//validate user credentials and obtain user roles (return List Roles)
//validar las credenciales de usuario y obtener roles de usuario
var user = model.User = _serviceUsuario.ObtenerUsuario(context.UserName, context.Password);
if (user == null)
{
context.SetError("invalid_grant", "El nombre de usuario o la contraseña no son correctos.cod 01");
return;
}
var stringRoles = user.Roles.Replace(" ", "");//It depends on how you bring them from your DB
string[] roles = stringRoles.Split(',');//It depends on how you bring them from your DB
var identity = new ClaimsIdentity(context.Options.AuthenticationType);
foreach(var Rol in roles)
{
identity.AddClaim(new Claim(ClaimTypes.Role, Rol));
}
identity.AddClaim(new Claim(ClaimTypes.Name, context.UserName));
identity.AddClaim(new Claim(ClaimTypes.Email, user.Correo));
identity.AddClaim(new Claim(ClaimTypes.MobilePhone, user.Celular));
identity.AddClaim(new Claim("FullName", user.FullName));//new ClaimTypes
identity.AddClaim(new Claim("Empresa", user.Empresa));//new ClaimTypes
identity.AddClaim(new Claim("ConnectionStringsName", user.ConnectionStringsName));//new ClaimTypes
//add user information for the client
var properties = new AuthenticationProperties(new Dictionary<string, string>
{
{ "userName",user.NombreUsuario },
{ "FullName",user.FullName },
{ "EmpresaName",user.Empresa }
});
//end
var ticket = new AuthenticationTicket(identity, properties);
context.Validated(ticket);
}
In past MVC versions I was able to do
<roleManager enabled="true" defaultProvider="...." ...
in to the web.config to get a custom role provider, but that doesn't seem to be the case anymore.
Essentially what I want to do is:
The user logs in.
On success, get roles for user from external source.
Apply roles to user to be used in code.
Match user roles to roles in custom RoleProvider
How do I do this in ASP.NET Core?
If you're using simple cookie-based authentication instead of the Identity framework, you can add your roles as claims and they will be picked up by User.IsInRole(...), [Authorize(Roles = "...")], etc.
private async Task SignIn(string username)
{
var claims = new List<Claim>
{
new Claim(ClaimTypes.Name, username)
};
// TODO: get roles from external source
claims.Add(new Claim(ClaimTypes.Role, "Admin"));
claims.Add(new Claim(ClaimTypes.Role, "Moderator"));
var identity = new ClaimsIdentity(
claims,
CookieAuthenticationDefaults.AuthenticationScheme,
ClaimTypes.Name,
ClaimTypes.Role
);
await HttpContext.SignInAsync(
CookieAuthenticationDefaults.AuthenticationScheme,
new ClaimsPrincipal(identity),
new AuthenticationProperties
{
IsPersistent = true,
ExpiresUtc = DateTime.UtcNow.AddMonths(1)
}
);
}
