(RADIATOR) Re: Redundancy for RADIUS

[Hugh Irvine]

Hello Surajh -

This is a difficult problem with no single good answer.

How do people on the list provide redundancy?

My personal view is that a single "high-availability" database server 
is best, but then you are back in the situation of having a single 
point of failure.

regards

Hugh

NB: have you included a copy of your configuration file (no secrets),
together with a trace 4 debug showing what is happening?
