Unable to install packages from Azure's package repository

[vodik]

Describe the bug
Looks like Azure put their python package index behind an authorization mechanisms that redirects you through a login portal in such a way that this package gets confused. Pip seems to handle this scheme correctly.

unearth: Collecting links from https://pypi.org/simple/some-package/

To Reproduce
Add a source entry like this in pdm:

[[tool.pdm.source]]
url = "https://${TOKEN}@pkgs.dev.azure.com/coherentpath/core/_packaging/cp/pypi/simple/"
verify_ssl = true

And then adding a package provided by said repository.

System (please complete the following information):

The credentials are passed via Basic Authentication. Does pip support that use case though?

Hi vodik,

I had to use this URL scheme (as listed in the guide):

https://<feedname>:<token>@pkgs.dev.azure.com/<org>/<project>/_packaging/<feedname>/pypi/simple/

I am not using ssl but I don't think it's the issue. I've been downloading packages from Azure index for months with no issues.

@vodik Can you try on the latest stable version?
