LIBRARY

PARAMETERS

TPHandle (input) 

The handle that describes the certification authority module used to perform this function.

PreferredAuthority (input/optional)
  

The identifier which uniquely describes the Certificate Service Authority to submit the request to.

RequestType (input)
  

The identifier of the type of request to submit.

RequestInput (input)
  

A pointer to the input parameters to be submitted to the authority who will perform the requested service.

CallerAuthContext (input/optional)
  

This structure contains a set of caller authentication credentials. The authentication information can be a passphrase, a PIN, a completed registration form, a certificate, or a template of user-specific data. The required set of credentials is defined by the service provider module and recorded in the MDS Primary relation. Multiple credentials can be required. If the local service provider module does not require credentials from a caller, then the CallerCredentials field of this verification context structure can be NULL. The structure optionally contains additional credentials that can be used to support the authentication process. Authentication credentials required by the authority should be included in the RequestInput. The local service provider module can forward this credential information to the authority, as appropriate, but is not required to do so.

EstimatedTime (output)
  

The number of estimated seconds before the service results are ready to be retrieved. A (default) value of zero indicates that the results can be retrieved immediately via the corresponding CSSM_TP_RetrieveCredResult() (CSSM API), or TP_RetrieveCredResult() (TP SPI), function call. When the local service provider module or the authority cannot estimate the time required to perform the requested service, the output value for estimated time is CSSM_ESTIMATED_TIME_UNKNOWN.

ReferenceIdentifier (output)
  

A reference identifier, which uniquely identifies this specific request. The handle persists across application executions and becomes undefined when all local processing of the request has completed. Local processing is completed in one of two ways:

  • For certificate services that do not require explicit confirmation by the requester, the reference identifier is invalidated when the corresponding CSSM_TP_RetrieveCredResult() (CSSM API), or TP_RetrieveCredResult() (TP SPI), function completes (by returning valid results or by failure, which blocks returned results)

  • For certificate services that require explicit confirmation by the requester, the reference identifier is invalidated by successfully invoking the function CSSM_TP_ConfirmCredResu() (CSSM API), or CSSM_TP_ConfirmCredResult() (TP SPI).

DESCRIPTION

If the caller is successfully authenticated, then this function submits a request to the Authority identified by PreferredAuthority. The authority service can be local or remote. If the Authority is not specified, then the TP module can assume a default authority based on the RequestType and the CallerAuthContext. RequestType indicates the type of Authority request and RequestInput specifies the input parameters needed by the authority to perform the request.

The request is submitted to the authority only if the TP module can successfully authenticate the caller. The CallerAuthContext presents the caller's credentials and a list of one or more policies under which the caller should be authenticated. Caller credentials can be presented in several forms:

  • Memory-resident credential values, directly referenced by the structure

  • Data bases containing credentials

  • Callback functions that can be invoked to obtain credentials from an active entity

The local service provider must select and forward the credentials required by the Authority. The caller must provide all necessary credentials through the CallerAuthContext parameter.

If the caller can not be authenticated by the local service provider, the function fails and the request is not submitted to the selected authority.

This function returns a ReferenceIdentifier and an EstimatedTime (specified in seconds). ReferenceIdentifier is an ID for the submitted request. EstimatedTime defines the expected time to process the request. This time may be substantial when the request requires offline authentication procedures by the Authority process. In contrast, the estimated time can be zero, meaning the result can be obtained immediately using CSSM_TP_RetrieveCredResult() (CSSM API), or TP_RetrieveCredResult() (TP SPI). After the specified time has elapsed, the caller must use the function CSSM_TP_RetrieveCredResult() (CSSMAPI), or TP_RetrieveCredResult() (TP SPI), with the reference identifier, to obtain the result of the request.

RETURN VALUE

A CSSM_RETURN value indicating success or specifying a particular error condition. The value CSSM_OK indicates success. All other values represent an error condition.
