This is the default behavior of the MAX. The RADIUS RFC does NOT
the NAS to always try first the primary server. In fact, the idea of a
primary/secondary server is a Livingston idea that most people copied.
Ascend, suprise, uses the one the is responded the best. Until the
RADIUS server has a problem, it will not switch back.

Point both of your RadiusNT servers at your primary DB. Thats the
easiest way to fix it. If your primary DB goes down, you can manually
switch them to the less recent, Secondary DB.
