My Virtual Smart Zone is 18.104.22.168.1331 ，then I use Proxy(SZ Authenticator)，Create Radius ，
Test AAA by PAP is Good。
But when I actually connect back to Radius through the AP, it fails
Error log display "chap: ERROR: &control:Cleartext-Password is required for authentication"
I want use Protocol PAP , where can i do it set ?
