didmos is a software solution for Identity & Access Management and consists of various different modules, that can be used individually for different tasks or in combination.

For a general overview of the software solution, please refer to the following document:

Various parts of the didmos software suite have already been updated to version 2. This version is a consequent move towards  a modern micro services based software architecture for the already existing didmos modules. In addition, completely new modules are provided. This documentation covers all of these modules.


didmos V2 is made up of the following individual modules, which are illustrated above. Each module consists of a general version, which is open source and can be accessed as described below. Additionally, most modules can be extended at specific extension points to add custom functionality. A general purpose version of the frontend application (LUI) is also published as 'didmos2-demo-frontend'.

How to get started

In addition to the source code repositories, there is also a dedicated 'compose'-repository which contains a Docker-based development environment, build pipelines and deployment instructions. The general purpose version of didmos is called didmos2-demo and its compose-repository is accessible here:

At that location you can find details on how to setup a development environment, which currently is only fully documented for the Fedora operating system. The repository can also be used to setup a local demo environment based on pre-build docker images.

The most recent version of didmos2-demo is v2.2.0:
