IIS 7.5 FTP IIS Manager Users Login Fail (530)

I'm trying to set up a FTP site on IIS 7.5 that allows IIS Manager Users to login. I'm following this guide: http://learn.iis.net/page.aspx/321/configure-ftp-with-iis-7-manager-authentication/.

After set up, I cannot login to the FTP using an IIS Manager User account. The client error I got was
530 User cannot log in.
Win32 error: Unspecified error.
Error details: An error occured during the authentication process.

I tried both with or without a virtual host. A Windows account login fine.

The only strange thing I noticed was that when setting up Read permission for Network Service, there was an access denied error when setting up permission for "%SystemDrive%\Windows\System32\inetsrv\config\schema".

Any thoughts? Thanks!

Turned out I didn't install FTP Extensibility. There were two sub-items under FTP Service in IIS Role Features. I only selected the first one and didn't enable FTP Extensibility, which IIS Manager User and ASP.NET Membership rely on.
