This patch fixes two bugs introduced in
commit 339f2a4d4b487afa53fa99d72c35b16f31e417d3
Author: David Sommerseth <d...@users.sourceforge.net>
Date: Thu Apr 29 23:35:45 2010 +0200
David's patch replaced openvpn_execve() with openvpn_run_script() in two places,
but didn't adjust the return value handling. openvpn_run_script() returns true
or false, while openvpn_execve() returns the program's exit code.
Without the fix, the --tls-verify script and the --auth-user-pass-verify
script fail to run. (I noticed the latter, but haven't actually tested the
former.)
The return value handling is fine for the other places where
openvpn_run_script() is used, because those places previously used
openvpn_execve_check() (notice the "_check" suffix).
