We have seen issues with fullchain.pem files containing one self-signed
certificate. At the same time, the failing configuration was not
providing any client certificates or keys.
The error from curl was `"self signed certificate in the chain"`.
The openssl binary is not available so we cannot even c_rehash the
certificate directory when using `--capath`, however this worked already
with a fully signed fullchain.pem along with a client certificate and
key. So we cannot only use `--cacert` which will break that use case.
This is becoming really obscur on why using `--cacert` solves this
problem. I just can't wait to use the `vault` binary, that's all I can
say...
