c# LDAP can not Reset Password [SOLVED]

Hi Everyone ,

When i am working with LDAP noticed that the resetting password is very problematic . Finally i have found a solution.First of all you should configure your ¬†activedirectory server with ssl authentication i’m not sure it isnecessary
but too many blogs and forums say to do that. Well ,to do so ūüôā

And use this code to reset password in your client application

public static void ResetPassword(string dn,string userCN,string newpassword, string admin,string adminpass)
{
    //Create an active directory context
    DirectoryContext objContext = new DirectoryContext(DirectoryContextType.Domain,
        dn,
        admin,//you need admin privs.
        adminpass);
    Domain objDomain = Domain.GetDomain(objContext);
    DirectoryEntry de = objDomain.GetDirectoryEntry();
    //geting user password
    DirectoryEntry passUser = de.Children.Find("OU=PORTAL").Children.Find("CN=" + userCN);
    using (passUser)
    {
        //this is the common error line if you do not set correct configuration
        passUser.Invoke("SetPassword", new object[] { newpassword });
        passUser.CommitChanges();//don't forget to commint
    }
}

Usage is simple:

ResetPassword(“testdomain.umbrellacorp.local”, “MyTestUser”, “secret”, “testdomain\\admin”, “adminsecret”);

Someone who encounter with “Invoke SetPassword” error that possible forget to use DirectoryContext class.
DirectoryContext is the key point .This class can access server with appropriate connection settings.You dont need to
set any client configuration for example port,protocol etc.

Happy codding …
