  Glad to help.

  I agree.

  TBH, I like this proposal for securing EAP-TLS.  It may take time to deploy, but adding more clarity to certificates is always useful.  I'd be in favour of WG adoption of a document based on this.

  FWIW, a configuration file that creates certificates with the NAIRealm is located here:
