Entra Emulator is a local, MSAL-compatible emulator of Microsoft Entra ID
(Azure AD) in a single Go binary: the OIDC/OAuth 2.0 v2.0 endpoints MSAL
talks to, a minimal read-only Microsoft Graph, and an admin REST API — so
you can develop sign-in, token acquisition, and protected-API calls
offline with no cloud tenant. Local development tool only.
