Explicit Proxy Authentication Methods

[Anne]

Hi there,

This is a question about Explicit Proxy policy.

For fortigate Expliict Proxy (v5.2.7), what Authentication Methods can be used? I can only get the Basic method working.

Does NTLM works only with FSSO. I have setup local SSO on Fortigate (Poll Active Directory Server)

I have setup an Explicit Proxy with FSSO groups (usin Poll AD server method), Enabled IP Based AUthentication, selected

Signe Sign-on method as FSSO and Default Authentication Method as NTLM and select OK, I get a message "Input value is Invalid"

Does NTLM method only works with Software based FSSO?
