DPAM Native API for DigitalPersona Access Management

Functions

This section lists the Pro Authentication API functions. For a detailed description of each function’s parameters, consult the header file DPAlAuthSdkApi.h.

Function	Description
DPAlInit	Initialize the authentication functions. Calling this function is optional. If you do not call it, the system will initialize itself. However if you are going to call multiple authentication functions, it is more efficient and provides better performance if you initialize and terminate explicitly.
DPAlTerm	Terminate the authentication process, release resources. You must call DPAlTerm once for each time that you called DPAlInit.
DPAlAuthentication	Display multi-factor authentication dialog and authenticate a user. Optionally return the type of credentials used to authenticate and/or a secret upon successful authentication. Note that this function performs a 1-to-1 comparison -- matching a user’s credentials against their enrolled credentials in the DigitalPersona database.
DPAlIdentAuthenticate	For Kiosk environments only. Display multi-factor identification dialog and identify a user. Optionally return the username, the type of credential(s) used to authenticate and/or user secret(s) upon successful identification. Note that this function performs a 1-to-many comparison, searching Active Directory to find the user, and then authenticates the user.
DPAlReadAuthPolicy	Read an authentication policy.
DPAlWriteSecret	Save the requested secret (authenticated users only).
DPPTDoesSecretExist	Check to see if a secret exists.
DPAlBufferFree	Release memory buffer allocated by the other functions in the API.
DPAlFormatMessage	Returns a message string corresponding to an error code generated by the API. The string is returned in the language of the current user.
