public final class PasswordExpiredControl
extends Control
implements DecodeableControl

This class provides an implementation of the password expired control as described in draft-vchu-ldap-pwd-policy. It may be included in the response for an unsuccessful bind operation to indicate that the reason for the failure is that the target user's password has expired and must be reset before the user will be allowed to authenticate. Some servers may also include this control in a successful bind response to indicate that the authenticated user must change his or her password before being allowed to perform any other operation.

No request control is required to trigger the server to send the password expired response control. If the server supports the use of this control and the corresponding bind operation meets the criteria for this control to be included in the response, then it will be returned to the client.

Example

The following example demonstrates a process that may be used to perform a simple bind to authenticate against the server and handle any password expired or password expiring control that may be included in the response:

   BindRequest bindRequest =
        new SimpleBindRequest("uid=john.doe,ou=People,dc=example,dc=com",
                              "password");
   try
   {
     BindResult bindResult = connection.bind(bindRequest);
     for (Control c : bindResult.getResponseControls())
     {
       if (c instanceof PasswordExpiringControl)
       {
         System.err.println("WARNING:  Your password will expire in " +
              ((PasswordExpiringControl) c).getSecondsUntilExpiration() +
              " seconds.");
       }
       else if (c instanceof PasswordExpiredControl)
       {
         System.err.println("WARNING:  You must change your password " +
              "before you will be allowed to perform any other operations.");
       }
     }
   }
   catch (LDAPException le)
   {
     for (Control c : le.getResponseControls())
     {
       if (c instanceof PasswordExpiredControl)
       {
         System.err.println("ERROR:  Your password is expired.");
       }
     }
   }
