Add the following functions:
rad_request_authenticator() Returns the Request-Authenticator relevant to the most recently received RADIUS response. rad_server_secret() Returns the Shared Secret relevant to the most recently received RADIUS response. Neither of these functions should be necessary, however, the MS-MPPE-Recv-Key and MS-MPPE-Send-Key Microsoft Vendor Specific attributes are supplied in a mangled (encrypted) format, requiring this information to demangle. It's not clear whether these functions should be replaced with a rad_demangle() function or whether these attributes are one-offs. Sponsored by: Monzoon
