Authorize by a token from Azure Entra?

[svenakela]

Hi, it seems I can solve an auth task with caddy-security, can you please verify this?

We have an Azure Entra (formerly known as Active Directory).
We have Caddy servers acting as reverse proxies.
I would like to verify that a request is authorized to get to a url /internal/data.
My thought was to check if there is a valid token with username suffix @mydomain.com or redirect to the Entra service.

Can I do this with an Authorize config?
