/**
|
|
* Represents an LDAP v3 server control that specifies that you want
|
|
* the server to use the specified DN's identity for this operation.
|
|
* (The OID for this control is 2.16.840.1.113730.3.4.12.)
|
|
* <P>
|
|
*
|
|
* You can include the control in any request by constructing
|
|
* an <CODE>LDAPSearchConstraints</CODE> object and calling the
|
|
* <CODE>setServerControls</CODE> method. You can then pass this
|
|
* <CODE>LDAPSearchConstraints</CODE> object to the <CODE>search</CODE>
|
|
* or other request method of an <CODE>LDAPConnection</CODE> object.
|
|
* <P>
|
|
*
|
|
* For example:
|
|
* <PRE>
|
|
* ...
|
|
* LDAPConnection ld = new LDAPConnection();
|
|
* try {
|
|
* // Connect to server.
|
|
* ld.connect( 3, hostname, portnumber, "", "" );
|
|
*
|
|
* // Create a "critical" proxied auth server control using
|
|
* // the DN "uid=charlie,ou=people,o=acme.com".
|
|
* LDAPProxiedAuthControl ctrl =
|
|
* new LDAPProxiedAuthControl( "uid=charlie,ou=people,o=acme.com",
|
|
* true );
|
|
*
|
|
* // Create search constraints to use that control.
|
|
* LDAPSearchConstraints cons = new LDAPSearchConstraints();
|
|
* cons.setServerControls( sortCtrl );
|
|
*
|
|
* // Send the search request.
|
|
* LDAPSearchResults res = ld.search( "o=Airius.com",
|
|
* LDAPv3.SCOPE_SUB, "(cn=Barbara*)", null, false, cons );
