Configure token consumers using JAX-RPC to protect message authenticity at the server or cell level

The token consumer on the server or cell level is used to specify the information that is needed to process the security token if it is not defined at the application level.

You need to understand that the keystore/alias information that provided for the generator, and the keystore/alias information that provided for the consumer are used for different purposes. The main difference applies to the Alias for an X.509 callback handler.
When used in association with an encryption consumer, the alias supplied for the consumer is used retrieve the private key to decrypt the message. A password is required. When associated with a signature consumer, the alias supplied for the consumer is used strictly to retrieve the public key used to resolve an X.509 certificate that is not passed in the SOAP security header as a BinarySecurityToken. A password is not required.
WAS provides default values for bindings. We must modify the defaults for a production environment.
We can configure the token consumers on the server level and the cell level. In the following steps, use the first step to access the server-level default bindings and use the second step to access the cell-level bindings.

Procedure

Access the default bindings for the server level.

Click Servers > Server Types > WebSphere application servers > server_name
.

Under Security, click JAX-WS and JAX-RPC security runtime.
Mixed-version environment: In a mixed node cell with a server using Websphere Application Server version 6.1 or earlier, click Web services: Default bindings for Web Services Security.mixv

Click Security > Web services to access the default bindings on the cell level.

Under Default consumer bindings, click Token consumers.

Click New to create a token consumer configuration, click Delete to delete an existing configuration, or click the name of an existing token consumer configuration to edit its settings. If you are creating a new configuration, enter a unique name for the token consumer configuration in the Token consumer name field. For example, you might specify sig_tcon. This field specifies the name of the token consumer element.

Specify a class name in the Token consumer class name field. The JAAS Login Module implementation is used to validate (authenticate) the security token on the consumer side.
Restriction: The com.ibm.wsspi.wssecurity.token.TokenConsumingComponent interface is not used with JAX-WS web services. If you are using JAX-RPC web services, this interface is still valid.
The token consumer class name must be similar to the token generator class name.
For example, if the application requires an X.509 certificate token consumer, you can specify the com.ibm.wsspi.wssecurity.token.X509TokenGenerator class name on the Token generator panel and the com.ibm.wsspi.wssecurity.token.X509TokenConsumer class name in this field. WAS provides the following default token consumer class implementations:

com.ibm.wsspi.wssecurity.token.UsernameTokenConsumer

This implementation integrates a user name token.

com.ibm.wsspi.wssecurity.token.X509TokenConsumer

This implementation integrates an X.509 certificate token.

com.ibm.wsspi.wssecurity.token.LTPATokenConsumer

This implementation integrates a Lightweight Third Party Authentication (LTPA) token.

com.ibm.wsspi.wssecurity.token.IDAssertionUsernameTokenConsumer

This implementation integrates an IDAssertionUsername token.
A corresponding token generator class does not exist for this implementation.

Select a certificate path option. The certificate path specifies the certificate revocation list (CRL) used for generating a security token wrapped in a PKCS#7 with a CRL. WAS provides the following certificate path options:

None

If you select this option, the certificate path is not specified.

Trust any

If you select this option, any certificate is trusted. When the received token is consumed, the certificate path validation is not processed.

Dedicated signing information

If you select this option, you can specify a trust anchor and a certificate store. When you select the trust anchor or the certificate store of a trusted certificate, configure the collection certificate store before setting the certificate path.
To define a collection certificate store on the server or cell level, see Configure the collection certificate on the server or cell level.

Select a trust anchor in the Trust anchor field. WAS provides two sample trust anchors. However, IBM recommends that you configure your own trust anchors for a production environment. For information on configuring a trust anchor, see Configure trust anchors on the server or cell level.

Select a collection certificate store in the Certificate store field. WAS provides a sample collection certificate store. If you select None, the collection certificate store is not specified. For information on specifying a list of certificate stores that contain untrusted, intermediary certificate files awaiting validation, see Configure trusted ID evaluators on the server or cell level.

Select a trusted ID evaluator from the Trusted ID evaluation reference field. This field specifies a reference to the Trusted ID evaluator class name that is defined in Trusted ID evaluators panel. The trusted ID evaluator is used for evaluating whether the received ID is trusted. If you select None, the trusted ID evaluator is not referenced in this token consumer configuration.
To configure a trusted ID evaluator, see Configure trusted ID evaluators on the server or cell level.

Select the Verify nonce option if a nonce is included in a user name token on the generator side. Nonce is a unique cryptographic number that is embedded in a message to help stop repeat, unauthorized attacks of user name tokens. The Verify nonce option is available if you specify a user name token for the token consumer and nonce is added to the user name token on the generator side.

Select the Verify timestamp option if a time stamp is included in the user name token on the generator side. The Verify Timestamp option is available if you specify a user name token for the token consumer and a time stamp is added to the user name token on the generator side.

Specify the local name of the value type for the integrated token. This entry specifies the local name of the value type for a security token that is referenced by the key identifier. This attribute is valid when Key identifier is selected as the key information type.
To specify the key information type, see Configure the key information for the consumer binding using JAX-RPC on the server or cell level. WAS has predefined value type local names for the user name token and the X.509 certificate security token. Enter one of the following local names for the user name token and the X.509 certificate security token. When you specify the following local names, you do not need to specify the URI of the value type:

Username token

http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#UsernameToken

X.509 certificate token

http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-x509-token-profile-1.0#X509v3

X.509 certificates in a PKIPath

http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-x509-token-profile-1.0#X509PKIPathv1

A list of X.509 certificates and CRLs in a PKCS#7

http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-x509-token-profile-1.0#PKCS7

To specify Lightweight Third Party Authentication (LTPA) or token propagation (LTPA_PROPAGATION), specify both the value type local name and the Uniform Resource Identifier (URI). For LTPA, specify LTPA for the local name and http://www.ibm.com/websphere/appserver/tokentype/5.0.2 for the URI. For LTPA token propagation, specify LTPA_PROPAGATION for the local name and http://www.ibm.com/websphere/appserver/tokentype for the URI. For example, when an X.509 certificate token is specified, you can use http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-x509-token-profile-1.0#X509v3 for the local name. When you specify the local name of another token, specify a value type Qname. For example: uri="http://www.ibm.com/custom, localName=CustomToken

Specify the value type uniform resource identifier (URI) in the URI field. This entry specifies the namespace URI of the value type for a security token that is referenced by the key identifier. This attribute is valid when Key identifier is selected as the key information type on the Key information panel for the default generator. When you specify the token consumer for the user name token or an X.509 certificate security token, you do not need to specify this option. If you specify another token, you need to specify the URI of the QName for the value type.

Click OK and then Save to save the configuration. After saving the token generator configuration, you can specify a JAAS configuration for your token consumer.

Click the name of your token generator configuration.

Under Additional properties, click JAAS configuration.

Select a JAAS configuration from the JAAS configuration name field.
The field specifies the name of the JAAS system for application login configuration. We can specify additional JAAS system and application configurations by clicking Security > Global security. Expand JAAS, then click Application logins > New or System logins > New .
For more information on the JAAS configurations, see JAAS configuration settings. Do not remove the predefined system or application login configurations. However, within these configurations, you can add module class names and specify the order in which WAS loads each module. WAS provides the following predefined JAAS configurations:
