[RADIATOR] SIP2 + Fortigate setup

[Chad Roseburg]

Thanks Heikki ~ there is an option to change the authentication scheme. I
changed it to PAP as you suggest.

Now it appears as though the fortigate is sending the password encrypted
...Ex:

Test credentials:
user: 29030pretend
pass: gulash

Server output excerpt:
DEBUG: SIP2 send '2300020140219    141804AO|AA29030pretend|ACterminal
password|AD�$.%�6Է!H�'

In looking at the docs, I see several encryption/decrypt options ...what do
I include in my config to allow Radiator to decrypt
this password?

Thank you!

Chad
