Trying to change password with Modify Request, 'Server will disconnect' LdapException thrown.

[Carlo.Accorsi]

Hi, I'm trying to use a modify request to change the password so that I can 
process the response the response if it doesn't' meet the password policy 
requirement.


connection is connected and authenticated as the user, not an admin.
 The pwdReset flag is set TRUE but there are remaining grace logins.

                                Entry entry = connection.lookup(dn);
              Attribute at = entry.get("userPassword");
              Modification mod = new DefaultModification( 
ModificationOperation.REPLACE_ATTRIBUTE, at);

                     ModifyRequest modRequest = new ModifyRequestImpl();
                     PasswordPolicy ctrl = new PasswordPolicyImpl();
                     modRequest.addControl(ctrl);
                     modRequest.addModification(mod);
                     ModifyResponse modResponse = 
connection.modify(modRequest); // exception thrown here..
                                                processResponse(modResponse);   
//would like to process the response controls from there so that the 
appropriate error can be raised to the UI.
