The RADIUS access decision involves not only checking the credentials, but 
also validating the authorizations as well. So it seems that the 
authorizations  also potentially reside on the RADIUS server.

I think this means that there needs to be a statement about which 
authorizations take precedence.

In some cases there can be a mix of local and remote authentication -- a 
target can have local users and authentication methods and if the identity 
or authentication method is not one of those, then the authentication is 
remoted.  I think this implies that RADIUS will take precedence for 
authorization of a remote user, but that local authorizations are used for 
local users.
