[Openvpn-devel] [PATCH] Avoid repetition of "this config may cache passwords in memory"

[David Sommerseth]

From: David Sommerseth <d...@users.sourceforge.net>

For OpenVPN clients with long living connections, this message is repeated
everytime the connection is renegotiated.  This patch removes this behaviour
and will only show this warning once.
