  You're having a web page update RADIUS clients in SQL, and you're
worried about a "secure" GUI?  That makes no sense.

  If the application can update the SQL data, you've already lost most
of the security of your system.  It means that someone breaking in
through that application can update SQL, and then use a malicious
RADIUS client to further attack the server.

  A web GUI updating the configuration for a security-critical
application isn't a very "elegant" solution, either.

  Pick your battles.  If you're going to drive around with your card
windows rolled down, it doesn't make much sense to lock the doors for
extra "security".

  The NAS will keep sending the accounting information until it gets a

  And to answer a question you didn't ask, you're making the
assumption that a HUP will kill the server.  It won't.  It will cause
the server to re-read it's configuration files.  Nothing more.
