I have a domain controller on windows 2008 server R2, The users are able to modify their password through a web page. Once it's done, the users are still able tu use the old password as well as the new one at the next logon. The old password is still active only one time after the change, after that it's no more possible to use it...
I invoke the "ChangePassword" function.
Any Idea ? Is it a parameter to configure on the server ? Is it cached somewhere on the computer of the users ?
Thank you in advance
Here is my code:
/// Summary description for Ldap
public class Ldap
protected DirectoryEntry connectToLDap(String domain, String userName, String password)
de = new DirectoryEntry("LDAP://" + domain);
de.Username = userName;
de.Password = password;
de.AuthenticationType = AuthenticationTy
