[Bug-gnu-radius] Why GNU Radius does not follow RFC in client/server exchange?

[Yuri Kulaghin]

Hello!
As I see in the sources GNU Radius makes Authenticator field in packet
header as random bytes set, i.e. without any using of the shared secret!
Moreover, Authenticators of all packets during one second are equal
because srand(time(NULL)) is called at each Authenticator making!
What can it say about GNU Radius secure after that?
Correct me if I am mistaken.
