      hi,

      when trying to connect to pfsence ipkv2 server i receive the following errors:

      OpenSSL X.509 parsing failed
      found unsupported critical X.509 extension: 1.3.6.1.4.1.311.21.10
      critical 'msApplicationCertPolicies' extension not supported
      

      it basically means that linux does not like the microsoft certificates, which is ok as we have been working with it all using the following workaround (clientsided):

      /etc/strongswan.d/libstrongswan-relax-constraints.conf

      libstrongswan {
        x509 {
          enforce_critical = no
        }
      

      But in pfsence log I see the same error messages, so I created /var/etc/ipsec/libstrongswan-relax-constraints.conf and added the afore mentioned content. I also set "enforce_critical = no" in /var/etc/ipsec/strongswan.d/charon.conf. but error remains the same.

      any ideas ?

      PS : Why is "locate" not working when connecting to pfsense in a terminal (command not found) ? In freebsd it should be installed by default

        that setting on server side is not necessary. once we setup the radius server correctly the X509 error messages were gone.
