/**
* This class provides an implementation of an LDAP control that can be included
* in a bind request to request that the Directory Server return the
* authentication and authorization entries for the user that authenticated.
*
*
* NOTE: This class, and other classes within the
* {@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.
*
*
* The value of this control may be absent, but if it is present then will be
* encoded as follows:
*
* The following example demonstrates the process for processing a bind
* operation using the get authorization entry request control to return all
* user attributes in both the authentication and authorization entries:
