The following function execution throws an error. The same command in bash works like a charm.

```
def set_kibana_password():
headers = {"Content-Type": "application/json"}
payload = {"password": os.getenv('ELASTIC_PASSWORD')}
response = requests.put(
    url='https://localhost:9200/_xpack/security/user/kibana/_password',
    auth=HTTPBasicAuth('elastic', os.getenv('ELASTIC_PASSWORD')),
    cert='/certs/ca/ca.crt',
    headers=headers,
    data=payload
)
logging.info(str(response))

```

The output:

```
DEBUG:urllib3.connectionpool:Starting new HTTPS connection (1): localhost:9200

    context.load_cert_chain(certfile, keyfile)
ssl.SSLError: [SSL] PEM lib (_ssl.c:3845)

```

Bash:

```
curl -u elastic:$ELASTIC_PASSWORD -X PUT -H 'Content-Type: application/json' \
  --cacert /certs/ca/ca.crt \
  'https://localhost:9200/_xpack/security/user/kibana/_password' \
  -d '{ "password": "$ELASTIC_PASSWORD" }'
```

Hi,

You are using a wrong parameter with python-requests. The `cert` parameter is for passing in a client certificate to do authentication, and when you do that you also need to pass the respective private key ( which you don't and this is why urllib3 throws an error )

What you should be passing instead is the `verify` parameter that controls the CA certificates that are used to verify the server certificates and is the logical equivalent of using `--cacert` in `curl`. See [https://requests.kennethreitz.org/en/master/user/advanced/#ssl-cert-verification](https://requests.kennethreitz.org/en/master/user/advanced/#ssl-cert-verification) for more details.
