Configure the server to validate signature authentication information

 

Overview

Important distinction between V5.x and v6.x applications

Note: The information in this article supports v5.x applications only that are used with WAS v6.x. The information does not apply to v6.0.x applications.

Use this task to configure signature authentication at the server. Signature authentication refers to an X.509 certificate sent by the client to the server. The certificate is used to authenticate to the user registry configured at the server. After a request is received by the server that contains the certificate, the server needs to log in to form a credential. The credential is used for authorization. If the certificate supplied cannot be mapped to an entry in the user registry, an exception is thrown and the request ends without invoking the resource. For more information on signature authentication, see Signature authentication method.

Complete the following steps to configure the server to validate signature authentication:

 

Procedure

  1. Launch an assembly tool. For more information on the assembly tools, see Assembly tools.

  2. Open the J2EE perspective by clicking Window > Open perspective > Other > J2EE.

  3. Click EJB Projects > appname > ejbModule > META-INF.

  4. Right-click the webservices.xml file, and click Open with > Web services editor.

  5. Click the Binding Configurations tab, which is located at the bottom of the Web services editor within the assembly tool.

  6. Expand the Request receiver binding configuration details > Login mapping section.

  7. Click Edit to view the login mapping information or click Add to add new login mapping information. The login mapping dialog is displayed and you select (or enter) the following information:

    Authentication method

    Specifies the type of authentication. Select Signature to use signature authentication.

    Configuration name

    Specifies the Java Authentication and Authorization Service (JAAS) login configuration name.  For the signature authentication method, enter system.wssecurity.Signature for the JAAS login configuration name.  This specification logs in with the com.ibm.wsspi.wssecurity.auth.module.SignatureLoginModule JAAS login module.

    Use token value type

    Determines if you want to specify a custom token type.  For the default authentication method selections, one can leave this field blank.

    URI and local name

    When you select Signature method, one cannot edit the token value type URI and local name values.  Specifies custom authentication types.  For signature authentication, one can leave this field blank.

    Callback handler factory class name

    Creates a JAAS CallbackHandler implementation that understands the following callback handlers:

    • javax.security.auth.callback.NameCallback

    • javax.security.auth.callback.PasswordCallback

    • com.ibm.wsspi.wssecurity.auth.callback.BinaryTokenCallback

    • com.ibm.wsspi.wssecurity.auth.callback.XMLTokenReceiverCallback

    • com.ibm.wsspi.wssecurity.auth.callback.PropertyCallback

    For any of the default authentication methods (BasicAuth, IDAssertion, and Signature), use the callback handler factory default implementation.  Enter the following class name for any of the default authentication methods including signature: 

    com.ibm.wsspi.wssecurity.auth.callback.WSCallbackHandlerFactoryImpl

    This implementation creates the correct callback handler for the default implementations.

    Callback handler factory property name and callback handler factory property value

    Specifies callback handler properties for custom callback handler factory implementations. You do not need to specify any properties for the default callback handler factory implementation.  For signature, one can leave this field blank.

    Login mapping property name and login mapping property value

    Specifies properties for a custom login mapping to use.  For the default implementations including signature, one can leave this field blank.

 

What to do next

Specify how the server handles the signature authentication method. See Configuring the server to support signature authentication if you have not previously specified this information.
