How to change username in Active Directory

Question

I want to change the user .NET applications from Active Directory in my application.

Now I change it like this:

DirectoryEntry userToUpdate = updatedUser.GetDirectoryEntry(); userToUpdate.Properties["sAMAccountName"].Value = user.NewLogin; userToUpdate.CommitChanges(); 

But it does not work as I expect. When I check the "Active Directory Users and Computers" entry for this user, then on the "account" tab, I see that:
- The "Username" property is not updated
- Fixed updating the property "Login to login (pre-Windows 2000)."

How to update username in AD from C # code? What property should I set in DirectoryEntry, or is there another way to change the username.

Answer 1

There are two login names in AD:

 sAMAccountName = User logon name, (pre-windows 2000) Format/Usage: domain\user.name (note, your code will only populate user.name) userPrincipalName = User logon name Format/Usage: [e-mail] 

You need to update both.

Answer 2

Try userPrincipalName instead of sAMAccountName .
