Hi JJK,
I test you function and I've got this result:
> ok = 0
> cert DN: /C=AU/ST=Some-State/O=Internet Widgits Pty Ltd
> ok = 1
> cert DN: /C=AU/ST=Some-State/O=Internet Widgits Pty Ltd
Why I see this 2 time?
When I create the certificates I didn't fill with any special information,
just type enter in every question that is made. Did you think this could
cause this issue?
Kind regards.
