                              CallbackHandler cbh)

Method Detail

setControlFlags

cleanSubject

public void cleanSubject(MessageInfo messageInfo,
                         Subject subject)
                  throws AuthException

Description copied from interface: ServerAuth

Remove method specific principals and credentials from the subject.

Specified by:

cleanSubject in interface ServerAuth

Parameters:

messageInfo - - A contextual object that encapsulates the client request and server response objects, and that may be used to save state across a sequence of calls made to the methods of this interface for the purpose of completing a secure message exchange.

subject - - The Subject instance from which the Principals and credentials are to be removed.

Throws:

AuthException - if an error occurs during the Subject processing.

secureResponse

public AuthStatus secureResponse(MessageInfo messageInfo,
                                 Subject serviceSubject)
                          throws AuthException

Description copied from interface: ServerAuth

Secure a service response before sending it to the client. This method is called to transform the response message acquired by calling getResponseMessage (on messageInfo) into the mechanism-specific form to be sent by the runtime.

This method conveys the outcome of its message processing either by returning an AuthStatus value or by throwing an AuthException.

Specified by:

secureResponse in interface ServerAuth

Parameters:

messageInfo - - A contextual object that encapsulates the client request and server response objects, and that may be used to save state across a sequence of calls made to the methods of this interface for the purpose of completing a secure message exchange.

serviceSubject - - A Subject that represents the source of the service request, or null. It may be used by the method implementation as the source of Principals or credentials to be used to secure the request. If the Subject is not null, the method implementation may add additional Principals or credentials (pertaining to the source of the service request) to the Subject.

Returns:

An AuthStatus object representing the completion status of the processing performed by the method. The AuthStatus values that may be returned by this method are defined as follows:

• AuthStatus.SEND_SUCCESS when the application response message was successfully secured. The secured response message may be obtained by calling getResponseMessage on messageInfo.
• AuthStatus.SEND_CONTINUE to indicate that the application response message (within messageInfo) was replaced with a security message that should elicit a security-specific response (in the form of a request) from the peer. This status value serves to inform the calling runtime that (to successfully complete the message exchange) it will need to be capable of continuing the message dialog by processing at least one additional request/response exchange (after having sent the response message returned in messageInfo). When this status value is returned, the application response must be saved by the authentication module such that it can be recovered when the module’s validateRequest message is called to process the elicited response.
• AuthStatus.SEND_FAILURE to indicate that a failure occurred while securing the response message and that an appropriate failure response message is available by calling getResponseMessage on messageInfo.

Throws:

AuthException - When the message processing failed without establishing a failure response message (in messageInfo).

validateRequest

public AuthStatus validateRequest(MessageInfo messageInfo,
                                  Subject clientSubject,
                                  Subject serviceSubject)
                           throws AuthException

Description copied from interface: ServerAuth

Authenticate a received service request. This method is called to transform the mechanism-specific request message acquired by calling getRequestMessage (on messageInfo) into the validated application message to be returned to the message processing runtime. If the received message is a (mechanism-specific) meta-message, the method implementation must attempt to transform the meta-message into a corresponding mechanism-specific response message, or to the validated application request message. The runtime will bind a validated application message into the the corresponding service invocation.

This method conveys the outcome of its message processing either by returning an AuthStatus value or by throwing an AuthException

Specified by:

validateRequest in interface ServerAuth

Parameters:

messageInfo - - A contextual object that encapsulates the client request and server response objects, and that may be used to save state across a sequence of calls made to the methods of this interface for the purpose of completing a secure message exchange.

clientSubject - - A Subject that represents the source of the service request. It is used by the method implementation to store Principals and credentials validated in the request.

serviceSubject - - A Subject that represents the recipient of the service request, or null. It may be used by the method implementation as the source of Principals or credentials to be used to validate the request. If the Subject is not null, the method implementation may add additional Principals or credentials (pertaining to the recipient of the service request) to the Subject.

Returns:

An AuthStatus object representing the completion status of the processing performed by the method. The AuthStatus values that may be returned by this method are defined as follows:

• AuthStatus.SUCCESS when the application request message was successfully validated. The validated request message is available by calling getRequestMessage on messageInfo.
• AuthStatus.SEND_SUCCESS to indicate that validation/processing of the request message successfully produced the secured application response message (in messageInfo). The secured response message is available by calling getResponseMessage on messageInfo.
• AuthStatus.SEND_CONTINUE to indicate that message validation is incomplete, and that a preliminary response was returned as the response message in messageInfo. When this status value is returned to challenge an application request message, the challenged request must be saved by the authentication module such that it can be recovered when the module’s validateRequest message is called to process the request returned for the challenge.
• AuthStatus.SEND_FAILURE to indicate that message validation failed and that an appropriate failure response message is available by calling getResponseMessage on messageInfo.

Throws:

AuthException - When the message processing failed without establishing a failure response message (in messageInfo).
