GeoServer Access Control List (ACL)

GeoServer ACL is an advanced authorization system for GeoServer.

It consists of an independent application service that manages access rules, and a GeoServer plugin that requests authorization limits on a per-request basis.

As an administrator you'll use GeoServer ACL to define rules that grant or deny access to published resources based on service request properties such user credentials, the type of OWS service, and layers being requested.

These rules can be as open as to grant or deny access to whole GeoServer workspaces, or as granular as to specify which geographical areas and layer attributes to allow a specific user or user group to see.

As a user you'll perform requests to GeoServer such as WMS GetMap or WFS GetFeatures, and the ACL-based authorization engine will limit the visibility of the resources and contents of the responses to those matching the rules that apply to the request properties and the authenticated user credentials.

GeoServer ACL is not an authentication provider. It's an authorization manager that will use the authenticated user credentials, whether they come from Basic HTTP, OAuth2/OpenID Connect, or whatever authentication mechanism GeoServer is using, to resolve the access rules that apply to each particular request.

GeoServer ACL is Open Source, born as a fork of GeoFence. As such, it follows the same logic to define data access and administrative access rules. So if you're familiar with GeoFence, it'll be easy to reason about GeoServer ACL.

Building

Requirements:

  • Java 17 JDK

A Java 17 JDK is required to build the project.

The artifacts (e.g. those under src/domain and src/plugin ) that are part of the GeoServer plugin will still be compiled to Java 11 class compatibility.

./mvnw clean install

A Makefile is also provided with useful targets for the CI build:

  • make lint: validates source code and pom.xml files formatting. Used to fail the build if ill-formatted code or project configuration is pushed to github.
  • make format: applies source code and pom.xml formatters, may modify files. Useful to ensure code and project configurations are properly formatted before pushing commits to github.
  • make package: builds the projects without installing the maven artifacts to the local maven repository.
  • make test: runs unit and integration tests.
  • make build-image: builds a Docker image for the GeoServer ACL application.
  • make push-image: pushes the Docker image to docker hub.
