NS_VERIFY_SSL=False but OSError: Could not find a suitable TLS CA certificate bundle

[busch]

Hello,

I try to get your script working against an ADC with a self-signed certificate on the management interface. So I have set the
NS_VERIFY_SSL=False
environment variable.

I still receive a SSL verification error:

raise IOError("Could not find a suitable TLS CA certificate bundle, "
OSError: Could not find a suitable TLS CA certificate bundle, invalid path: False

Any chance to disable certificate validation entirely?
