ProxiedAuthorizationControl : can't find anywhere!

Question

Hi.
I have to connect to SunOne LDAP. I've already checked it supports ProxiedAuthorizationControl (OID = "2.16.840.1.113730.3.4.18"). In JDK 1.6 there is no class implementig this control. In some old posts I found references to com.sun.jndi.ldap.ctl.ProxiedAuthorizationControl and relevant examples. Also downloaded ldapbp.zip, but it does not include this class.
So this class seems to have disappeared! Anybody knows how to connect to SunOne as proxied user, or how to find ProxiedAuthorizationControl class?
Thanks.

Here's the solution, thanks to Sun's support. Following is a code example, should anybody incur on the same problem.
Hashtable<String, String> env = new Hashtable<String, String>();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://myldap:33389/");
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, "uid=userwithproxyauth,ou=users,dc=mygroup,dc=eu");
env.put(Context.SECURITY_CREDENTIALS, "mypassword");
// Bind to LDAP - bind user has proxy rights
LdapContext ldapCtx = new InitialLdapContext(env, null);
// Set proxied user
String dn = "uid=C010000,ou=people,dc=mygroup,dc=eu";
ldapCtx.setRequestControls(new Control[]{new BasicControl("2.16.840.1.113730.3.4.18", true, ("dn: " + dn).getBytes())});
// The following operation is performed acting as C010000 user
ModificationItem[] mods = new ModificationItem[1];
mods[0] = new ModificationItem(DirContext.REPLACE_ATTRIBUTE, new BasicAttribute("userpassword", "newpassword"));
System.out.println("DEBUG: setting new password: newpassword");
ldapCtx.modifyAttributes(dn, mods);
That's all folks!
