Certificate auth issue in 0.2.2

[weeker at outlook.com (Karl)]

Hi,

In my config, it has:

auth = "certificate"
auth = "plain[/opt/ocserv/passwd]"

but AnyConnect client failed to connect, debug log shows:

 "No certificate was found."

add "always-require-cert=false", it goes further, but still has error like:

"error verifying client certificate."

Did I miss something or buggy in 0.2.2?

Thanks!
