/**
* This class provides support for an UnboundID-proprietary SASL mechanism that
* may be used to indicate that a user has attempted authentication, whether
* successfully or not, through some mechanism that is external to the Directory
* Server. If this mechanism is supported in the server, then attempting to
* authenticate with it will not change the identity of the client connection,
* but will perform additional processing that would normally be completed
* during a more traditional authentication attempt.
*
*
* NOTE: This class is part of the Commercial Edition of the UnboundID
* LDAP SDK for Java. It is not available for use in applications that
* include only the Standard Edition of the LDAP SDK, and is not supported for
* use in conjunction with non-UnboundID products.
*
*
* This SASL bind request has a mechanism of
* "UNBOUNDID-EXTERNALLY-PROCESSED-AUTHENTICATION" and must
* include SASL credentials with the following encoding:
*
* In the event that the external authentication was considered successful, the
* server will ensure that the target user's account is in a usable state and,
* if not, will return a failure response. If the external authentication was
* successful and the user's account is usable, then the server will make any
* appropriate password policy state updates (e.g., clearing previous
* authentication failures, updating the user's last login time and IP address,
* etc.) and return a success result.
*
* In the event that the external authentication was not considered successful,
* the server may also make corresponding password policy state updates (e.g.,
* incrementing the number of authentication failures and locking the account if
* appropriate) before returning a failure result.
