The SAMLSPServer component represents a SAML service provider.

Syntax

TsbxSAMLSPServer

Remarks

The Service Provider in the SAML exchange flow represents the web server that receives and accepts authentication assertions issued by the Identity Provider for single sign-on (SSO). Most commonly, an SP server is part of the application responsible for communicating with an Identity Provider to establish the authenticity of application users.

SAMLSPServer provides easy means of integrating the SAML Service Provider functionality into your application. It presents a fully-features SP endpoint with its own HTTP(S) and assertion validation engines.

Please find below a step-by-step guide on setting up your own SAML SP endpoint.

• Register the IdP metadata using the LoadIDPMetadata method or its stream-based variant. Most IDPs let you download their metadata in XML format. The metadata file contains general parameters of the IdP endpoint, such as its web address and algorithm requirements. server.LoadIDPMetadata("their_metadata.xml"); // contains "<?xml version="1.0"?><md:EntityDescriptor ID="ab12" ... </md:EntityDescriptor>";
• Configure the main server capabilities: // public server endpoint (use "https://" and/or port 443 if required) server.URL = "http://sp.myapp.com"; server.Port = 80; // IdP triggers this URL to pull metadata server.MetadataURL = '/sp/metadata'; // ACS is th "main" SP endpoint that receives assertions from the IdP server.AssertionConsumerService = '/sp/AssertionConsumerService'; server.SPToIDPBinding = csbtRedirect; // the SP will use HTTP redirect to forward the browser to the IdP when required server.AssertionConsumerServiceBindings = 'POST'; // and we want the IdP to use POST to submit its assertions server.PreferredIDPToSPBinding = csbtPOST; // Single logout service setup server.SingleLogoutService = '/sp/SingleLogoutService'; server.SingleLogoutServiceBindings = 'Redirect,POST,Artifact'; server.LogoutPage = '/sp/logout'; server.RedirectOnLogoutPage = 'https://www.nsoftware.com'; // The document root of the server on the local system server.BaseDir = "D:\\Inetpub\\SAMLSP"; // Security parameters: indicating that we want to sign both // the metadata and the requests server.SignAuthnRequests = true; server.SignMetadata = true; // We need to attach certificates to be able to sign. // Assume we have loaded our signing certificate into // a CertificateManager object. server.SigningCertificate = mgr.Certificate; server.MetaSigningCertificate = mgr.Certificate;
• Personalize the server: server.Config("OrganizationName=My Organization Ltd"); server.Config("OrganizationDisplayName=My Organization Pet Supplies"); server.Config("OrganizationURL=http://myorg.com"); server.Config("SigDigestMethod=http://www.w3.org/2001/04/xmlenc#sha256"); server.Config("SigMethod=http://www.w3.org/2001/04/xmldsig-more#rsa-sha256"); server.Config("WantAssertionsSigned=true");
• Optionally, save metadata to an XML file. This will let you send/upload it to the IdP, so they could set your SP up. Some IdPs can download the metadata right from your SP using the MetadataURL that you've provided above, in which case saving it to a file is not necessary. server.SaveMetadata("my_metadata.xml");

You are now ready to start the server: server.Start(); The server should now be running on the local system, listening to incoming connections on the port that you have specified above (80). Use your browser to check if the server is responding by navigating to the metadata URL (http://127.0.0.1:80/sp/metadata). If the server has been set up right, you should see something like this:

Now let us actually try to use the SAML functionality. Copy an arbitrary file - for example, a recent photo of your cat - to the directory you provided earlier via the BaseDir property (D:\Inetpub\SAMLSP). Having copied the file (suppose it is called clifford.jpg), try to access it in your browser by navigating to http://127.0.0.1:80/clifford.jpg.

This is where SAML kicks in. Since you are not authenticated for the SP server yet (we have just launched it, so no one is), the server redirects your browser to the IdP endpoint for authentication. The address of the IdP is taken from the their_metadata.xml file that you have loaded at the very beginning.

Note: you can configure which resources to restrict access to using the ProtectedResources property. If ProtectedResources is empty, the server considers all the files in BaseDir and its subfolders to be protected.

It is now the IdP services turn to authenticate you. Most IdPs on this stage will present you with a login form. Yet, if you have signed in recently, the IdP may still remember you, in which case it will skip the form and proceed directly to the next step. After establishing and proving your identity, the IdP will generate an assertion, a signed proof that effectively states that the IdP knows who you are and have verified your identity rigorously. Think of the assertion as your unique pass to the resources protected by the SP. The IdP will then submit that assertion back to the SP at its AssertionConsumerService endpoint, again using your browser.

Note that the SP service knows nothing about how IdP authenticates you. All the SP is interested in is an assertion.

If the assertion is well-formed and its signature is valid, the SAML exchange completes. At this point the SP accepts the assertion and creates a session for you. You can now access the resources protected by the SP for as long as the session lasts. If this step succeeds, you should see the photo of your cat in your browser.

Please make sure the URL you provide here aligns well with the relative endpoint resource paths, such as AssertionConsumerService or ArtifactResolutionService. The two parts (the URL and the endpoint paths) are concatenated to produce full endpoint URLs. Please double check that only one of the parts includes the slash character in it: either the endpoint paths at the beginning (the default configuration), or the base URL at the end.

Config Method (SAMLSPServer Component)

Sets or retrieves a configuration setting.

Syntax

function Config(ConfigurationString: String): String;

Remarks

Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

  const HashAlgorithm: String;
  const Pars: String;
  const Data: String;
  var SignedData: String
) of Object;

property OnExternalSign: TExternalSignEvent read FOnExternalSign write FOnExternalSign;

Remarks

Assign a handler to this event if you need to delegate a low-level signing operation to an external, remote, or custom signing engine. Depending on the settings, the handler will receive a hashed or unhashed value to be signed.

The event handler must pass the value of Data to the signer, obtain the signature, and pass it back to the component via SignedData parameter.

OperationId provides a comment about the operation and its origin. It depends on the exact component being used, and may be empty. HashAlgorithm specifies the hash algorithm being used for the operation, and Pars contain algorithm-dependent parameters.

The component uses base16 (hex) encoding for Data, SignedData, and Pars parameters. If your signing engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the signing.

A sample MD5 hash encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

A sample event handler that uses a .NET RSACryptoServiceProvider class may look like the following: signer.OnExternalSign += (s, e) => { var cert = new X509Certificate2("cert.pfx", "", X509KeyStorageFlags.Exportable); var key = (RSACryptoServiceProvider)cert.PrivateKey; var dataToSign = e.Data.FromBase16String(); var signedData = key.SignHash(dataToSign, "2.16.840.1.101.3.4.2.1"); e.SignedData = signedData.ToBase16String(); };

  var Metadata: String
) of Object;

property OnMetadataRequest: TMetadataRequestEvent read FOnMetadataRequest write FOnMetadataRequest;

Remarks

The component uses this event to notify the application about an incoming metadata request. The suggested metadata text is provided through the Metadata parameter. The application can adjust it as required if it needs to.

Notification Event (SAMLSPServer Component)

This event notifies the application about an underlying control flow event.

Syntax

type TNotificationEvent = procedure (
  Sender: TObject;
  const EventID: String;
  const EventParam: String
) of Object;

property OnNotification: TNotificationEvent read FOnNotification write FOnNotification;

Remarks

The component fires this event to let the application know about some event, occurrence, or milestone in the component. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.

The unique identifier of the event is provided in EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the component, the exact action it is performing, or the document being processed, one or both may be omitted.

ResourceClose Event (SAMLSPServer Component)

Tells the application that it can close the opened resource.

Syntax

type TResourceCloseEvent = procedure (
  Sender: TObject;
  ConnectionID: Int64
) of Object;

property OnResourceClose: TResourceCloseEvent read FOnResourceClose write FOnResourceClose;

Remarks

The component uses this event to notify the application that it can now close the resource opened earlier in its ResourceOpen handler.

After closing the resource, set the OperationStatus according to the outcome of the operation.

ResourceOpen Event (SAMLSPServer Component)

Requests the application to open the requested resource.

Syntax

type TResourceOpenEvent = procedure (
  Sender: TObject;
  ConnectionID: Int64;
  const URL: String;
  var OperationStatus: Integer
) of Object;

property OnResourceOpen: TResourceOpenEvent read FOnResourceOpen write FOnResourceOpen;

Remarks

The component fires this event in virtualized mode if the application had returned the fraCustom modifier from the earlier ResourceRequest event call. Your code is expected to open the requested resource and be prepared to read from it in subsequent ResourceRead event calls. Check the operation status, and alter it, if needed, through the OperationStatus parameter:

ResourceRead Event (SAMLSPServer Component)

Requests the application to read from an opened resource.

Syntax

type TResourceReadEvent = procedure (
  Sender: TObject;
  ConnectionID: Int64;
  Size: Integer;
  var OperationStatus: Integer
) of Object;

property OnResourceRead: TResourceReadEvent read FOnResourceRead write FOnResourceRead;

Remarks

The component fires this event in virtualized mode to request another chunk of data from the resource opened earlier. The handler of this event should read up to Size bytes from the object, and pass them to the component with a SetClientBuffer call.

Use the OperationStatus parameter to return the operation result back to the server. When the file has been read up to its end, set OperationStatus to ostEOF to tell the components that no more ResourceRead calls are needed.

Set OperationStatus to one of the following values:

ResourceRequest Event (SAMLSPServer Component)

Notifies the application that a server resource is requested.

Syntax

type TResourceRequestEvent = procedure (
  Sender: TObject;
  ConnectionID: Int64;
  const URL: String;
  var ResProtected: Boolean;
  var ResSpecial: Boolean;
  var Action: Integer
) of Object;

property OnResourceRequest: TResourceRequestEvent read FOnResourceRequest write FOnResourceRequest;

Remarks

The component uses this event to notify the application that the connection has requested a server resource.

The URL parameter specifies the resource requested. ResProtected is set to true if the resource is protected by SAML. ResSpecial is set to true if the request is a SAML resource, such as the metadata or an Assertion Consumer Service page. ConnectionID identifies the connected client.

Set Action to fraAuto to let the server handle the request automatically, or to fraCustom to handle the request in your code ('virtualize' the request).

Choose Action as one of the following values:

SessionClosed Event (SAMLSPServer Component)

This event is fired when the SP server has closed a session.

Syntax

type TSessionClosedEvent = procedure (
  Sender: TObject;
  ConnectionID: Int64
) of Object;

property OnSessionClosed: TSessionClosedEvent read FOnSessionClosed write FOnSessionClosed;

Remarks

ConnectionID contains the identifier of the closed session.

SessionEstablished Event (SAMLSPServer Component)

This event is fired when a new session has been established.

Syntax

type TSessionEstablishedEvent = procedure (
  Sender: TObject;
  ConnectionID: Int64;
  const Username: String
) of Object;

property OnSessionEstablished: TSessionEstablishedEvent read FOnSessionEstablished write FOnSessionEstablished;

Remarks

ConnectionID contains the identifier of the new session, Username specifies the client's address and Username.

SessionStageChanged Event (SAMLSPServer Component)

Notifies the application about the change of SAML session stage.

Syntax

type TSessionStageChangedEvent = procedure (
  Sender: TObject;
  ConnectionID: Int64;
  const Session: String;
  const Stage: String
) of Object;

property OnSessionStageChanged: TSessionStageChangedEvent read FOnSessionStageChanged write FOnSessionStageChanged;

Remarks

component uses this method to notify your code about changed SAML session stage. The Session parameter specifies the session ID. The Stage parameter can take one of the following values:

• Start
• AuthnRequestSent
• ResponseReceived
• ResourceSupplied
• LogoutRequestSent
• LogoutResponseReceived
• LogoutRequestRecv
• LogoutResponseSent
• ArtifactResolveRecv
• ArtifactResponseSent
• Finish

Certificate Type

Provides details of an individual X.509 certificate.

Remarks

This type provides access to X.509 certificate details.

Fields

Constructors

>

constructor Create();

Creates a new object with default field values.

ExternalCrypto Type

Specifies the parameters of external cryptographic calls.

Remarks

External cryptocalls are used in a Distributed Cryptography (DC) subsystem, which allows the delegation of security operations to the remote agent. For instance, it can be used to compute the signature value on the server, while retaining the client's private key locally.

Fields

Constructors

>

constructor Create();

Creates a new ExternalCrypto object with default field values.

SocketSettings Type

A container for the socket settings.

Remarks

This type is a container for socket-layer parameters.

Fields

Constructors

>

constructor Create();

Creates a new SocketSettings object.

TLSSettings Type

A container for TLS connection settings.

Remarks

TLS (Transport Layer Security) protocol provides security for information exchanged over insecure connections such as TCP/IP.

Fields

Constructors

>

constructor Create();

Creates a new TLSSettings object.

Config Settings (SAMLSPServer Component)

The component accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.
