/**
* This class defines a Directory Server task that can be used to cause the
* server to enter lockdown mode, in which case it will only allow requests
* from users with the lockdown-mode privilege. Lockdown mode is intended to
* allow administrators to perform operations with the server online but without
* worrying about the impact that those operations may have on other users. In
* In some special cases, the server may place itself in lockdown mode as a
* defense mechanism rather than risking the exposure of sensitive information.
* For example, if the server detects any malformed access control rules at
* startup, then it will place itself in lockdown mode rather than attempt to
* run without that rule in effect since it could have been intended to prevent
* unauthorized users from accessing certain data.
*
*
* 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.
*
*
* The enter lockdown mode task does not have any task-specific properties. See
* the {@link LeaveLockdownModeTask} class for the corresponding mechanism to
* bring the server out of lockdown mode.
