Using a "default" configuration, OpenVPN clients show the following warning when connecting to a VPN server in red, attention-seeking letters:
WARNING: this configuration may cache passwords in memory -- use the auth-nocache option to prevent this
Googling for that configuration option yields various Internet sources that claim that this is not really a big deal, but I want to get rid of that warning, because I don't want my VPN users to get in the habit of ignoring warnings written in red.
Obviously, I can do that by adding auth-nocache to the configuration file.
What's the drawback of doing that? Since this feature is "opt-in", there must be some kind of drawback, or it would be enabled by default. Unfortunately, searching for "auth-nocache" in the official documentation yielded no results.
