Change Windows Password from RTC client

Hi,

Maybe a stupid question, but is it possible to change the Windows password when using the RTC with a different AD login than the local domain login? The problem is, we have a new NAV server with its own domain and we set an initial password for each user. But there is no possibility to change the password in RTC directly. So we would need to predefine the logins for each user and they will never be able to change it.

Any ideas?

Best regards,
Felix
