This release provides optional support for authenticating your users over your Windows Active Directory using SSO (Single Sign On), having users provide their Windows credentials. To use this feature, check out the magic.lambda.ad-auth project.
It basically works by allowing you to include one NuGet package, for then to exchange the default password invocation to an invocation that checks your AD credentials through a simple configuration setting. This again exchanges the default password invocation with checking your Windows credentials instead in your Windows AD.
The logic is completely interchangeable, allowing you to also provide your own external authentication scheme, completely independently, dynamically exchanging which slot to invoke to check your users' passwords.
