How to Code in VS.net to Change AD User's Password

[Ching Liang]

In my web application, I need to authenticate users to the AD and allow users to change the password. From my readings, I find out that I have to use DirectoryEntry class to authenticate the users with password. I do that OK. But I still cannot find a way to allow users to change the password. Can anyone help? Thank you.

Hi Ching,

The following tutorial includes a method for changing and saving a user
password through Active Directory. Note that the examples work with the
"WinNT" provider. If working with a domain Active Directory, you will need
to work with the "LDAP" provider.

How about setting the new password to the DirectoryEntry object, and
then call the CommitChanges method.

I tried that and it did not work. I was hoping it would be that simple but it turned out not so. I am digesting Kevin's response. It seems that there are more security involved, such as impersonation.
