silently drop packet (access-request)

[Andriy Gapon]

Is there a way to force a silent drop of a packet instead of sending
Access-Reject ?
I am interested in both doing this through configuration file(s) and
doing this from a module (e.g. with some special return code or attribute).

On a somewhat related note: is there way to make FreeRADIUS server
drop/reject all incoming packets without Message-Authenticator the same
way it does this for packets with invalid/incorrect value in that
attribute ? Preferably through configuration, without changes in code.
