  I asked you to explain what you meant by "node" and "node identifier".  You haven't done that.

  What is a "node identifier" ?

  You've just giving the same explanation as the previous message.  Why do you think this is a good idea?

   Where is that attribute defined?

  If you edited raddb/dictionary, did you *READ* the comments in that file?

   Is it supposed to be there?  Why do you think it's supposed to be there?

  A proxy *cannot* modify the data inside of a TLS tunnel.  TLS is designed to prevent this...

  Don't attach the debug log.  Include it in the message.

  And PLEASE follow instructions.  It's "radiusd -X", not "radiusd -Xx", or "radiusd -xxxxxxxx".

  Read the documentation and follow it.  That helps a lot.
