Hello,
With the last version.
OPNsense 21.1.2-amd64
FreeBSD 12.1-RELEASE-p13-HBSD
OpenSSL 1.1.1j 16 Feb 2021
I set the voucher as authentication mode for proxy trought Services => Web Proxy => Administration => Forward Proxy ==> Authentication Settings => Authentication method = "Radius NAS, Voucher"
I've generated voucher with Services => Captive Portal => Vouchers.
When i use an unused voucher to authenticate, I get "Cache Access Denied".
With an Active Directory account retrieved with Radius, it's ok.
I'm not sure that using voucher from captive portal must be the good way. I haven't found where to generate voucher for Proxy.
Thanks by advance
