Change Active Directory User Password

Question

How to change the password of an Active Directory user using the directory service without knowing the old password?

Answer 1

You are probably looking for a method SetPasswordthat you should call on the object DirectoryEntry.

Check out the Reset User Password: Howto example here : (almost) everything in Active Directory through C # .

EDIT :
If you have problems with a null entry in the directory, you are likely to make a mistake. The path should be something like this:

DirectoryEntry entry = new DirectoryEntry("LDAP://CN=johndoe,CN=Users,DC=acme,DC=com");
