Hello !
We are using 2.7.1_1 amd64 version. The HAProxy GUI interface, in the section Client Certificate Auth, when setting "Verification" to "required", the GUI are set as "Required" in configuration and "test syntax" are going in error :
[NOTICE] (81003) : haproxy version is 3.0.11-9e587df
[NOTICE] (81003) : path to executable is /usr/local/sbin/haproxy
[ALERT] (81003) : config : parsing [/usr/local/etc/haproxy.conf.staging:46] : 'bind XXXXXXXXXXXX:443' in section 'frontend' : 'verify' : unknown verify method 'Required', only 'none', 'optional', and 'required' are supported
[ALERT] (81003) : config : Error(s) found in configuration file : /usr/local/etc/haproxy.conf.staging
[ALERT] (81003) : config : Fatal errors found in configuration.
There is some workaround here ? (replacing in /usr/local/etc/haproxy.conf.staging not working !)
Looks like this one https://github.com/opnsense/plugins/pull/4900
