It looks like I have to pay for a "Windows Azure Subscription" (I guess?) in order to create an OAuth application, although I'm having trouble even doing that (the form has a section called "Payment Information" but won't let me enter any, and the "Sign Up" button is greyed out).

I'll try again later, but we need to be able to test this before we can upstream it. It looks technically correct, but there's no way we can support it if I can't create an account and go through the workflow.

Their form is tricky: you first have to complete the mobile phone verification before to be able to fill credit card information. The area becomes visible some seconds (but not immediately) after code verification.

There is a free offer and by default, it's not possible to get charged, as the charge limit is configured to zero. Verifying the credit card, there is an usual temporary reservation fee (when I tested Azure, it were 1 €) liberated after some days.

What assistance could be offered to help this along? Setting up a test azure as app with access for the phabricator team?

You can find some discussion of how we prioritize in T4778.

It's important that we be able to test changes like this repeatably -- not just once. When we make unrelated changes to OAuth in the future, we need to be able to quickly assess that all of the providers still work. If some providers are very difficult to assess, that would tend to make us hesitant to make OAuth changes. We generally don't want features in the upstream which slow down or impair our ability to develop or test the software.

My experience earlier suggested that the minimum amount of effort to get this change into the upstream is substantial, and the difficulty of testing the provider might have a chilling effect on modifying providers. As such, it is very difficult for us to prioritize. There is nothing you can do to meaningfully reduce the repeatability barrier, so there is nothing you can do to get this into the upstream sooner other than register your interest in it. We've currently seen very little interest, so this is not likely to make it upstream in the near future.

Thanks for the insight. I guess my interest is registered, and I'll probably try to keep a patch like this maintained locally, and keep watching to see if azure does anything to lower the testing barrier.

Thanks!

Our company proudly and happily uses Phabricator for 2 years now. We use Azure and it would awesome if we could get rid of yet-another-use-account-base with this feature.

What kind of help can we offer to make this feature get int?
