[Feature Request] NTLM Proxy Authentication with credentials.

[chahilp]

There is a missing option to authenticate the proxy with credentials.

What I am trying to do?

1. I am trying to generate access token for the Graph API calls with oauth2.0.
2. I am using AAD client credentials flow under corporate proxy.

To be able to access external website such as https://microsoft.com or the api endpoints to generate access token requires proxy authentication with credentials which is being fulfilled by requests module in Python by auth=("proxyusername", "myproxypassword"), such similar option is being expected to authenticate proxy to reach microsoft cloud authentication endpoints to generate access toke.

Thanks for your patience.

MSAL Python provided some parameters and relay them to the underlying requests, but that approach is not scalable. So, nowadays, MSAL Python allows app developer to provide a customized http_client that can have all the behavior you choose to have.

If you just want to customize the proxy behavior, you may just rely on requests's environmental variable behavior.
