Setting LDAP Connection Request Controls
This example uses the JNDI/LDAP service provider to connect to an LDAP server on the local machine and initializes its connection request controls. 

 
 try {
     // Create connection controls to use
     Control[] connectCtls = new Control[]{
       new SomeControl()};
                 
     LdapContext ctx = new InitialLdapContext(
       env, connectCtls);
  } catch (NamingException e) {
 }
