Hi, With openvpn 2.4.5, we are using deferred mode for user verification through plugin library. Noticed there are a lot of auth_control_files are left around and wondering if we need to do our own clean up of these files outside of openvpn.
The scenario involves two factor authentication where end user has to approve through their smartphone app which may take some time. The left-over files mostly contains "0" which indicates a failure due to timeout. If the second factor authentication is done within a minute, then auth_control_file is deleted right away if the auth result is failure. The auth result is success, then the file is deleted when the connection is closed. Any suggestion is appreciated. Thanks. -chang
