/*
Radius implementation for the init_prot callback
For Radius, initialization consists of:
- the url is parsed and a configuration structure is obtained
- the rest field from the configuration structure is, for the radius
module, a string for the path of the radius configuration file
- obtain the connection handle
- initialize the dictionary
For Radius, the aaa_conn is actually the rc_handle resulted by reading
the Radius configuration file.
