  That's good.

  FreeRADIUS just processes packets it receives.  It does NOT create those packets, or any information in them.

  Ask Microsoft how their software works.

  FreeRADIUS just reports on what it sees.  It does not (and can not) cause the Windows system to send different User-Names.

  Ask Microsoft how to configure their software.

  If you receive an email from someone, you're not responsible for the contents.  The sender is responsible.  The same applies here.
