/**
* This class provides an implementation of the account usable response control,
* which may be returned with search result entries to provide information about
* the usability of the associated user accounts.
*
*
* 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.
*
*
* Information that may be included in the account usable response control
* includes:
*
*
{@code accountIsActive} -- Indicates that the account is active and may
* include the length of time in seconds until the password expires.
*
{@code accountIsInactive} -- Indicates that the account has been locked
* or deactivated.
*
{@code mustChangePassword} -- Indicates that the user must change his
* or her password before being allowed to perform any other
* operations.
*
{@code passwordIsExpired} -- Indicates that the user's password has
* expired.
*
{@code remainingGraceLogins} -- Indicates the number of grace logins
* remaining for the user.
*
{@code secondsUntilUnlock} -- Indicates the length of time in seconds
* until the account will be automatically unlocked.
*
* See the {@link AccountUsableRequestControl} documentation for an example
* demonstrating the use of the account usable request and response controls.
*
* This control was designed by Sun Microsystems and is not based on any RFC or
* Internet draft. The value of this control is encoded as follows:
