Authorization and account methods that the free radius supports?

["Liangliang Guo" <liangliang.guo@ericsson.com>]

Hi everyone:

Does anybody know what kinds of authorization and account methods that
the free radius supports. At the official wiki, authentication methods
are documented in details. However for authorization methods only some
supported database backbends are described, and for accounting only some
conceptual introduction to accounting are available?
Can anyone throw some lights on them.   


Best Regards
