OpenVPN issue on rc21: I experience a very big oddity when a plugin is initialized with OPENVPN_PLUGIN_AUTH_USER_PASS_VERIFY flag on, but the VPN config is set to TLS: on ssl.c, we get into the "if" on line 2581, but this is IMO not correct. Then we go further to read_string on line 2589 and finally fail.
I also wonder if something of the sort happens then the VPN is set to work with U/P and the plugin is initialized with OPENVPN_PLUGIN_TLS_VERIFY. The problem, is that the plugin may be initialized for informational purposes only to handle the event. The bigger problem, is that one configuration may have TLS and another one U/P, and both may use the same plugin. My plugin sends all the event to an ODBC source, therefore suffering a great deal from this IMO broken behaviour. IMO, the condition on line 2581 should lead in this case directly to the "else" on line 2624 to behave correctly. Unfortunately I am not legally allowed to contribute GPL'ed fixes, so I would appreciate a community fix. TIA, RN
