// Package iam implements an identity and access management middleware

// - resource
// - action

// The identity of the requester can be obtained by different means:
// - JWT
// - Username and password in the body as JSON
// - Auth0 access token
// - Basic auth
//
// The path prefix /api/login is treated specially in order to accomodate
// different ways of identification (UserPass, Auth0). All other /api paths
// only allow JWT as authentication method.
//
// If the identity can't be detected, the identity of "$anon" is given, representing
// an anonmyous user. If the request originates from localhost, the identity will
// be $localhost, representing an anonymous user from localhost.
//
// The domain is provided as query parameter "group" for all API requests or the
// first path element after a mountpoint for filesystem requests.
//
// If the domain can't be detected, the domain "$none" will be used.
//
// The resource is the path of the request. For API requests it's prepended with
// the "api:" prefix. For all other requests it's prepended with the "fs:" prefix.
