NAME

CSSM_DL_Authenticate — Provide authentication credentials (CDSA)

SYNOPSIS

# include <cssm.h>
API:
CSSM_RETURN CSSMAPI CSSM_DL_Authenticate
(CSSM_DL_DB_HANDLE DLDBHandle,
CSSM_DB_ACCESS_TYPE AccessRequest,
const CSSM_ACCESS_CREDENTIALS *AccessCred)
SPI:
CSSM_RETURN CSSMDLI DL_Authenticate
(CSSM_DL_DB_HANDLE DLDBHandle,
CSSM_DB_ACCESS_TYPE AccessRequest,
const CSSM_ACCESS_CREDENTIALS *AccessCred)

LIBRARY

Common Security Services Manager library (cdsa$incssm300_shr.exe)

PARAMETERS

DLDBHandle (input)
  

The handle pair that describes the add-in data storage library module used to perform this function and the data store to which access is being requested. If the form of authentication being requested is authentication to the DL module in general, then the data store handle must be NULL.

AccessRequest (input)
  

An indicator of the requested access mode for the data store or DL module in general.

AccessCred (input)
  

A pointer to the set of one or more credentials being presented for authentication by the caller. The credentials can apply to the DL module in general or to a particular data store managed by this service module. The credentials required for creating new data stores is defined by the DL and recorded in a record in the MDS Primary DL relation. The required set of credentials to access a particular data store is defined by the DbInfo record containing meta-data for the specified data store.

The credentials structure can contain multiple types of credentials, as required for multi-factor authentication. The credential data can be an immediate value, such as a passphrase, PIN, certificate, or template of user-specific data, or the caller can specify a callback function the DL can use to obtain one or more credentials.

DESCRIPTION

This function allows the caller to provide authentication credentials to the DL module at a time other than data store creation, deletion, open, import, and export. AccessRequest defines the type of access to be associated with the caller. If the authentication credential applies to access and use of a DL module in general, then the data store handle specified in the DLDBHandle must be NULL. When the authorization credential is to apply to a specific data store, the handle for that data store must be specified in the DLDBHandle pair.

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.

ERRORS

Errors are described in the CDSA Technical Standard.

CSSMERR_DL_INVALID_ACCESS_REQUEST
CSSMERR_DL_INVALID_DB_HANDLE
