Default Method Lists
For every authentication or accounting type, it is always possible to define a method list
called default. For most of the authentication and accounting types, the only method list
that can be defined is default.
As soon as the default method list is defined for a given authentication or accounting
type, it is automatically applied as the method list to be used for any instance of that type
of authentication or accounting, except for instances to which another named method list
has been specifically applied.
