      Dear All,

      Some time ago there was an issue with OpenVPN suddenly not accepting certain certificates anymore. This seems to be around:
      https://redmine.pfsense.org/issues/13056
      in German: https://www.andysblog.de/pfsense-openvpn-verbindungen-scheitern-an-certificate-does-not-have-key-usage-extension

      Then, there were patches though the patches pakage like:

      • OpenVPN Enforce key usage option fix
      • OpenVPN Enforce key usage option typo fix
      • Fix for CRL expiration lifetime default and maximum values (Redmine #13424)

      It seems that these packages did mitigate the problem for a while. Now, I am facing "Certificate does not have key usage extension" issues again, seemingly with older certificates and not so much with more recent certificates. The OpenVPN server does reject some certificates - which were in use for a long time without issues and which are not expored - while accepting others.

      Can someonne please be so kind to point me at what to do to solve this? Will there maybe be a new version of pfSense solving this in the near future?

      Regards,

      Michael Schefczyk
