Windows OpenVPN Client and tls-auth

The official Windows OpenVPN client does not seem to work properly with the tls-auth option if a key direction is used. The client will read your ovpn file, embed all the keys, and save it under <client install directory>\etc\profile. It seems to ignore the key direction for tls-auth. The fix is to go to the profile directory, give yourself permission to edit the profile, and add “key-direction 1″ before “<tls-auth>”. Remove the extra permissions after adding the line.
