 * Name: AddInAuthenticate
 *
 *Description:
 * This function is called by CSSM when the CSP is loaded.
 * It is used to register the CSP's function pointers with CSSM so that 
 * future calls from the application can be successfully dispatched to the CSP.
 * It is also the means by which the CSP receives the memory function pointers
 * that will be used to allocate data structures for the application.
 *
 *Parameters: 
 * cssmCredentialPath (input) : Unused
 * cssmSection        (input) : Unused
 * AppCredential      (input) : Unused
 * AppSection         (input) : Unused
 *
 *Return value:
 *   CSSM_FAIL                  - authentication failed
 *   CSSM_OK                    - authentication succeeded,
 * 
 *Error Codes:
 * None
