Since a longer time systemd suite contains a "userdb" component that allows local services to provide rich, extensible user records, that are consumed by various other systemd components. In this talk i'd like to explain what this is, and why identity management systems with a focus on local logins on Linux/systemd systems should consider implementing the necessary simple IPC interfaces and provide their user records in systemd's format.

This talk will cover various topics that are documented here:
