Authentication in C# with Active Directory

问题

I am trying to create an application that requires user authentication over active directory to return a token, but I am not sure how to use it correctly.

I've been looking at Authenticate user by ADFS (Active Directory Federation Service) but I am not sure how to create a Request Security Token or how to use it correctly.

Are there any working examples for this available? Any help is appreciated.

It depends on whether you're using WIF or .NET 4.5 System.IdentityModel.

Using WIF:

string endpointUri = string.Format("https://{0}/adfs/services/trust/13/usernamemixed", _serverName);

var factory = new Microsoft.IdentityModel.Protocols.WSTrust.WSTrustChannelFactory(
              new UserNameWSTrustBinding(SecurityMode.TransportWithMessageCredential),
              new EndpointAddress(endpointUri));

factory.TrustVersion = TrustVersion.WSTrust13;
if (factory.Credentials != null)
{
    factory.Credentials.UserName.UserName = "UserName";
    factory.Credentials.UserName.Password = "password";
}

var rst = new RequestSecurityToken
{
    RequestType = WSTrust13Constants.RequestTypes.Issue,
    AppliesTo = new EndpointAddress(_relyingPartyUri),
    KeyType = WSTrust13Constants.KeyTypes.Bearer,
};

var channel = factory.CreateChannel();
SecurityToken token = channel.Issue(rst);
return token;

Using .NET 4.5 System.IdentityModel, you'll need to define the UserNameWSTrustBinding yourself:

public class UserNameWSTrustBinding : WS2007HttpBinding
{
    public UserNameWSTrustBinding()
    {
        Security.Mode = SecurityMode.TransportWithMessageCredential;
        Security.Message.EstablishSecurityContext = false;
        Security.Message.ClientCredentialType = MessageCredentialType.UserName;
    }
}

string endpointUri = string.Format("https://{0}/adfs/services/trust/13/usernamemixed", _serverName);

var factory = new WSTrustChannelFactory(new UserNameWSTrustBinding(), endpointUri)
    {
        TrustVersion = TrustVersion.WSTrust13
    };

factory.Credentials.UserName.UserName = "UserName";
factory.Credentials.UserName.Password = "password";

var rst = new RequestSecurityToken
{
    RequestType = RequestTypes.Issue,
    AppliesTo = new EndpointReference(_relyingPartyUri),
    KeyType = KeyTypes.Symmetric
};

var channel = factory.CreateChannel();

return channel.Issue(rst);

It depends on which type of application you are using. Authentication over ADFS using WIF comes in two flavors: - Passive authentication using Asp.net web form or MVC. You can refer to this article: Claims Aware MVC4 App using WIF Identity and Access tool in .Net 4.5

Active authentication when the application is a Web Service like WCF. This article can help: Claims Aware WCF using WIF in .Net 4.5

Also depending on the .NET framework you are using, you will need to download either one of the following: - WIF Runtime and WIF SDK for .NET 4.0 - Identity and Access Tool for .NET 4.5
