  In general the NAS doesn't retry.  The end-user does (or their system).

  And a 10s timeout might work, but it's generally low.  If you set it to ~300, then the authentication might restart.

 Again, the RADIUS server is *not* in control here.  It can advise the NAS / end user to do something, but they are free to ignore the RADIUS servers recommendations.  This is one of the key concepts which is very hard to make people understand:  No amount of poking the RADIUS server will make the NAS do something.
