How I Got OpenStack Keystone Running on Windows: A Collection of Hacks

An experiment tried to run OpenStack Keystone natively on Windows.

It exposed heavy Linux assumptions: missing POSIX modules, Python 3.11 mismatches, and issues with eventlet and cryptography.

The setup required code patches, module swaps, and MariaDB tuning before Keystone could finally answer authentication requests.

The result highlights how deeply core open-source infrastructure can depend on Linux, making true cross-platform support difficult.
