public abstract class OneTimePasswordDeliveryMechanism
extends java.lang.Object
implements UnboundIDExtension, Reconfigurable<OneTimePasswordDeliveryMechanismConfig>, ExampleUsageProvider

This class defines an API that must be implemented by extensions which attempt to deliver one-time passwords (OTPs) to end users through some out-of-band mechanism. The one-time passwords will have been generated by the deliver one-time password extended request, and may be used to authenticate to the server through the UNBOUNDID-DELIVERED-OTP SASL mechanism.

Configuring One-Time Password Delivery Mechanisms

In order to configure a one-time password delivery mechanism created using this API, use a command like:

      dsconfig create-otp-delivery-mechanism \
           --mechanism-name "{mechanism-name}" \
           --type third-party \
           --set enabled:true \
           --set "extension-class:{class-name}" \
           --set "extension-argument:{name=value}"
 

where "{mechanism-name}" is the name to use for the one-time password instance, "{class-name}" is the fully-qualified name of the Java class that extends com.unboundid.directory.sdk.ds.api.OneTimePasswordDeliveryMechanism, and "{name=value}" represents name-value pairs for any arguments to provide to the one-time password delivery mechanism. If multiple arguments should be provided to the OTP delivery mechanism, then the "--set extension-argument:{name=value}" option should be provided multiple times.

deliverOneTimePassword

public abstract java.lang.String deliverOneTimePassword(java.lang.String oneTimePassword,
                                                        Entry userEntry,
                                                        java.lang.String targetRecipientID,
                                                        java.lang.StringBuilder resultMessage)
                                                 throws LDAPException

Attempts to deliver the provided one-time password to the specified user.

Parameters:

oneTimePassword - The one-time password to be delivered.

userEntry - The entry for the user to whom the one-time password should be delivered.

targetRecipientID - The target recipient ID that should be used for the delivery, if possible. It may be null if there is no appropriate identifier for this delivery mechanism or if the delivery mechanism may choose which recipient ID should be used. However, if it is non-null, then the delivery mechanism must verify that the provided recipient ID is valid for the associated user (e.g., for an e-mail delivery mechanism, the recipient ID would probably be an e-mail address, and the delivery mechanism must verify that the provided e-mail address is associated with the given user account).

resultMessage - A buffer to which a message may be appended with additional information about the password delivery.

Returns:

An identifier for the user in a format appropriate to the delivery mechanism (e.g., an e-mail address for an e-mail delivery mechanism, a phone number for an SMS or voice call delivery mechanism, etc.). It may be null if there is no appropriate identifier for this delivery mechanism that is needed beyond the name of the delivery mechanism and the DN of the recipient.

Throws:

LDAPException - If a problem is encountered while attempting to send the one-time password to the user. The exception should have a result code of TOKEN_DELIVERY_INVALID_RECIPIENT_ID if the client specified a recipient ID that is not valid for the target user, TOKEN_DELIVERY_MECHANISM_UNAVAILABLE if this delivery mechanism is not supported for the target user, or TOKEN_DELIVERY_ATTEMPT_FAILED if the delivery mechanism should be supported but the attempt to deliver the one-time password failed.

supportsGenericMessageDelivery

public boolean supportsGenericMessageDelivery()

Indicates whether this one-time password delivery mechanism supports general purpose message delivery via the deliverMessage(com.unboundid.directory.sdk.ds.config.OneTimePasswordDeliveryMechanismConfig, java.lang.String, java.lang.String, java.lang.String, java.lang.String, java.lang.String, com.unboundid.directory.sdk.common.types.Entry, java.lang.String, java.lang.StringBuilder) method.

Returns:

true if the deliverMessage method can be used for general-purpose message delivery, or false if only the deliverOneTimePassword method can be used.

deliverMessage

public java.lang.String deliverMessage(OneTimePasswordDeliveryMechanismConfig config,
                                       java.lang.String tokenID,

                                throws LDAPException

Attempts to deliver a message (containing a single-use token) to the specified user.

Parameters:

config - The general configuration for this OTP delivery mechanism.

tokenID - The token ID for the single-use token contained in the message to be delivered.

tokenValue - The value for the single-use token contained in the message to be delivered.

messageSubject - The message subject that should be used, if appropriate. It may be null if no subject was provided.

fullMessage - The message that should be delivered if this delivery mechanism does not impose a significant constraint on message size.

compactMessage - The message that should be delivered if this delivery mechanism does impose a significant constraint on message size.

userEntry - The entry for the user to whom the token should be delivered.

targetRecipientID - The target recipient ID that should be used for the delivery, if possible. It may be null if there is no appropriate identifier for this delivery mechanism or if the delivery mechanism may choose which recipient ID should be used. However, if it is non-null, then the delivery mechanism must verify that the provided recipient ID is valid for the associated user (e.g., for an e-mail delivery mechanism, the recipient ID would probably be an e-mail address, and the delivery mechanism must verify that the provided e-mail address is associated with the given user account).

resultMessage - A buffer to which a message may be appended with additional information about the token delivery.

Returns:

An identifier for the user in a format appropriate to the delivery mechanism (e.g., an e-mail address for an e-mail delivery mechanism, a phone number for an SMS or voice call delivery mechanism, etc.). It may be null if there is no appropriate identifier for this delivery mechanism that is needed beyond the name of the delivery mechanism and the DN of the recipient.

Throws:

LDAPException - If a problem is encountered while attempting to deliver the single-use token message to the user. The exception should have a result code of TOKEN_DELIVERY_INVALID_RECIPIENT_ID if the client specified a recipient ID that is not valid for the target user, TOKEN_DELIVERY_MECHANISM_UNAVAILABLE if this delivery mechanism is not supported for the target user, or TOKEN_DELIVERY_ATTEMPT_FAILED if the delivery mechanism should be supported but the attempt to deliver the token failed.
