/**
* This class provides an implementation of an extended request that may be used
* to revoke one or all of the TOTP shared secrets for a user so that they may
* no longer be used to authenticate.
*
*
* 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 request may be invoked in one of following ways:
*
*
*
* With a {@code null} authentication identity and a non-{@code null}
* TOTP shared secret. In this case, the authorization identity for the
* operation (typically the user as whom the underlying connection is
* authenticated, but possibly a different user if the request also includes
* a control like the proxied authorization or intermediate client request
* control that specifies and alternate authorization identity, or if the
* client authenticated with a SASL mechanism that included an alternate
* authorization identity) will be used as the authentication identity for
* this request, and only the specified TOTP shared secret will be removed
* from the user's entry while any other shared secrets that may be present
* in the user's entry will be preserved. If a static password is provided,
* then it will be verified, but if none is given then the provided TOTP
* shared secret will be considered sufficient proof of the user's identity.
*
*
* With a {@code null} authentication identity, a non-{@code null} static
* password, and a {@code null} TOTP shared secret. In this case, the
* authorization identity for the operation will be used as the
* authentication identity for this request, and, if the provided static
* password is valid, then all TOTP secrets contained in the user's entry
* will be revoked.
*
*
* With a non-{@code null} authentication identity and a non-{@code null}
* TOTP shared secret. In this case, only the provided TOTP shared secret
* will be removed from the specified user's account while any other shared
* secrets will be preserved. If a static password is provided, then it
* will be verified, but if none is given then the provided TOTP shared
* secret will be considered sufficient proof of the user's identity.
*
*
* With a non-{@code null} authentication identity a non-{@code null}
* static password, and a {@code null} TOTP shared secret. In this case,
* if the static password is valid for the specified user, then all TOTP
* shared secrets for that user will be revoked.
*
*
* With a non-{@code null} authentication identity a {@code null} static
* password, and a {@code null} TOTP shared secret. In this case, the
* authentication identity from the request must be different from the
* authorization identity for the operation, and the authorization identity
* must have the password-reset privilege. All TOTP shared secrets for
* the specified user will be revoked.
*
*
*
* This extended request has an OID of 1.3.6.1.4.1.30221.2.6.58, and it must
* include a request value with the following encoding:
*
