How to change the proxy authentication method from NTLM to BASIC?

Issue

I have a proxy that offers both NTLM & BASIC authentication, how to make yum use the BASIC authentication method instead of NTLM?
How to force a particular authentication method within yum?
yum fails with 407 Proxy Authentication Required
yum fails with [Errno 14] curl#22 - "Invalid file descriptor"
