### Our environment
Our digital work environment is composed of **many applications** and web services. We want a **seamless user experience** for our free software based collaboration platform. With a **Single Sign-on (SSO)** system users get a unified login and logout experience but there is a catch.

### Our problem
Traditional SSO protocols like OpenID Connect do **not support syncing user profiles across applications.** That's means :
* **users are not created by default in all apps** (only after they have logged in at least once)
* **no mechanisms to propagate the deletion of users**
* So its **not GDPR compliant** (by default)

#### In essence
<mark>Current existing protocols are **difficult to implement or/and to use** or are **custom for specific use case** then **non-standardized**.</mark>
