use of org.eclipse.scout.rt.shared.services.common.pwd.IPasswordManagementService in project scout.rt by eclipse.

the class PasswordPolicyVerifier method verify.

/**
 * Calls {@link IPasswordManagementService#getPasswordExpirationDate(String)} to check whether the password has
 * expired. When desired, warns the user in advance about the expiration. If expired, calls the
 * {@link DefaultPasswordForm#startChange()} and - when closed - re-checks the expiry date. When still expired, exits
 * the application (scout session).
 *
 * @param warnInAdvanceDays
 *          number of days before the expiry when a warning shall occur, -1 to omit this feature
 * @return true if the password is not expired, false if - after all - the password has expired. Normally when
 *         returned false, the application quits.
