I'd like to pose another naïve question about options for moving our
ancient text file based authentication system to something more modern and
general purpose.

Could we just use Azure Active Directory as a credentials and roles

I know that AD wasn't invented just for that purpose, but could I hijack it
and use it as a centralised database? I see there are lots of language
binding libraries available
including .NET flavours and Xamarin, so hopefully the code learning curve
is quite low. I'm not sure what the cost is like yet, I'm still poking
around web search results.
