  Which takes all of 10min.

  I've explained that putting encrypted passwords into the DB adds zero security, but doesn't really harm anything.  I've also explained that disabling the server cert validation is terrible, and actively harms security.

  Your response complaining about security professionals concentrating on the wrong thing is *entirely* inappropriate.

  I'll say it again: Amateurs SHOULD NOT be designing security systems.  You, and your managers, and the marketing people, are security amateurs.

  Listen to the experts, or ignore their advice.  It's up to you.  But do *not* respond by belittling the experts.  It's ignorant and anti-social.

  Then you didn't understand my comments.

  It's *terrible*.  It destroys *ALL SECURITY* in your RADIUS configuration.  The only worse thing you could do is to print out all of the user names and passwords, and post them in a public place.

  Learn how to learn from the experts.

  Then don't argue with the experts.

  Then learn from the experts.

  Honestly, I have no idea what the heck is going through peoples minds when they ask questions, and then argue with the answers.  It's completely narcissist.

  No, you're not the smartest person in the world.  You attempts at being humble are just ways to convince yourself that you can ignore the expert advice.

  Stop it.
