concess

⚠️ Early Development: This is not production ready, yet. Do not use it for anything important.

Introduction

concess is an over-simplified, featherweight, open-source and easy-to-use authentication and authorization server. It mimics a variety of authentication protocols while managing users in a simple list of files.

All data used and processed by concess is stored in a single directory containing a human-readable YAML file for every user.

Currently, the following methods are supported:

• LDAP
• RADIUS
• webauthn
• OpenID connect
• OAuth2

Building

concess is written in Rust, so a Rust installation is required. Currently, an unstable rust compiler is required to build the project.

To build:

$ git clone https://github.com/fooker/concess
$ cd concess
$ cargo build --release
$ ./target/release/concess --version

Usage

Create a config file called concess.yaml by adapting the Example.

After that, create the data directory in the location specified in the config file. In there, create users by creating a file per user in the users directory inside the data directory. Each user entry must follow the naming scheme NAME.yaml, whereas the NAME is the username of the user. See the Examples again for inspiration and syntax.

For groups, each user can be assigned to an arbitrary number of groups. There is no further configuration required for a group to exist - it will as long as there is at least a user in there.
