From: David Sommerseth <dav...@openvpn.net> This is an adopted version of [0] for the OpenVPN 2.4 release branch.
It was discovered an issue with OpenVPN 2.x when multiple --plugin modules were loaded and more than one of them used deferred authentication. To fix this properly will require a larger refactoring of the plug-in code, so it was decided in the mean time to disable the possibility to run an OpenVPN server with such a setup. This issue affects the OpenVPN server mode only. This patch set adds a new test plug-in and adds some test documentation on how to test various combinations of authentication plug-ins. Since this new plug-in (multi-auth.c) is fairly close to the simple.c plug-in, just more flexible for test setups, we remove the old one. The fix itself is isolated in a separate patch in this set. The order of patches are insignificant; there are no inter-dependencies between them.
