Support communication with vCenter Server via kerberos authenticated proxy sever

[VedaNiks]

Is your feature request related to a problem? Please describe.

I need to communicate with vCenter Server and all the traffic goes through a kerberos authenticated proxy sever. I am not able to authenticate the proxy server since the requests.session does not support/use 'Proxy-Authorization' header.
I am using below code:

import requests
import urllib3
from vmware.vapi.vsphere.client import create_vsphere_client
from requests_kerberos import HTTPKerberosAuth

kerb_auth = HTTPKerberosAuth(force_preemptive=True)
auth_header = kerb_auth.generate_request_header(None, '10.24.129.100', True)
session = requests.session()

# Disable cert verification for demo purpose.
# This is not recommended in a production environment.
session.verify = False
session.proxies = {
    'http': 'http://10.24.129.100:3128',
    'https': 'http://10.24.129.100:3128',
}
session.headers = {
    'Proxy-Authorization': auth_header
}

# Disable the secure connection warning for demo purpose.
# This is not recommended in a production environment.
urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)

# Connect to a vCenter Server using username and password
vsphere_client = create_vsphere_client(server='VC_IP',
                                       username='[email protected]',
                                       password='p@s$w0rD',
                                       session=session)

# List all VMs inside the vCenter Server
print(len(vsphere_client.vcenter.VM.list()))

Even for proxy server with basic authentication, we have to set proxy credentials as below:

session.proxies = {
    'http': 'http://squid_user:p@[email protected]:3128',
    'https': 'http://squid_user:p@[email protected]:3128'
}

Is there a way to connect to vCenter Server via kerberos authenticated proxy server by using VMware automation SDK python project?

Describe the solution you'd like

A way to authenticate proxy server which supports kerberos authentication.

Describe alternatives you've considered

The WAR for this is to directly use vCenter APIs with urllib3 library.
