EIMIS experimentation whitelist Synapse module

Use case

Let's say you run an experiment in which you operate a Matrix server. An external ID provider is configured but you want to allow only specific users to join the experiment. You also want an easy way to manage a user whitelist.

Whitelist module

To do so, this repo contains a Synapse Module that will use check_registration_for_spam hook. It will allow users based on their mention in a specific whitelist room 🤓

Try it out

some /etc/hosts entries

echo "127.0.0.1 idp.local" | sudo tee -a /etc/hosts
echo "127.0.0.1 matrix.local" | sudo tee -a /etc/hosts

Run the stack

docker compose up -d
