## Summary Adds immediate client disconnect when a certificate is revoked, via OpenVPN management interface. Previously, revoked clients stayed connected until they voluntarily disconnected or the server restarted. Fixes #1199 ## Changes - Enable management interface (Unix socket at `/var/run/openvpn/server.sock`) - Add `disconnectClient()` function to send `kill` command on revoke - Add `socat` dependency for socket communication
