* This class provides an implementation of an extended request which may be
* used to validate a TOTP password for a user. Note that this should not be
* used as an alternative to authentication because it does not perform password
* policy processing. Rather, this extended operation should be used only to
* obtain additional assurance about the identity of a user that has already
* been authenticated through some other means.
*

* {@code com.unboundid.ldap.sdk.unboundidds} package structure, are only
* supported for use against Ping Identity, UnboundID, and
* Nokia/Alcatel-Lucent 8661 server products. These classes provide support
* for proprietary functionality or for external specifications that are not
* considered stable or mature enough to be guaranteed to work in an
* interoperable way with other types of LDAP servers.
*
