Sanitized tls.conf from a working Radius TLS Proxy on the latest FR 3.x from GIT. Alan did push out an update which enabled Radius Accounting over TLS a week or two ago.

Alan thanks for your assistance getting this feature working.

  Home server pools, and home servers.  This has been in the server since v2.0.0.

  The realm "accthost" config has been deprecated since 2008. :(

  And see raddb/sites-available/tls.  There's complete documentation there.
