Description

Is your feature request related to a problem?

Yes - I'm the author of the Spark BigQuery connector which uses gRPC internally to communicate to the GCP APIs. A user is requesting to add support for NT Credentials for proxies.

Describe the solution you'd like

From the user's desription:

our proxy server only support NTCredentials to pass Authcations, we need to build a generic way to support Username, NT, Kerberos Poxy Auth. for our code we just need to replace usernamepasswordCredentials(user,pass) by NTCredentials(user,pass,null, region)

Describe alternatives you've considered

It seems there are none

Research direction
Start by examining the HttpConnectProxiedSocketAddress class in the grpc java codebase to understand how proxy credentials are currently handled. Look for existing credential types and how they are passed to the socket address. Investigate the NTCredentials class from libraries like Apache HttpClient and consider how to integrate it into the gRPC proxy authentication flow. Check the linked issue for more context on user requirements.
