Setting up Appservice Double Puppet (optional)

Appservice Double Puppet is a homeserver appservice through which bridges (and potentially other services) can impersonate any user on the homeserver.

This is useful for performing double-puppeting via the appservice method. The Appservice Double Puppet service is an implementation of this approach.

Previously, bridges supported performing double-puppeting with the help of the Shared Secret Auth password provider module, but this old and hacky solution has been superseded by this Appservice Double Puppet method.

Adjusting the playbook configuration

To enable the Appservice Double Puppet service, add the following configuration to your inventory/host_vars/matrix.DOMAIN/vars.yml file:

matrix_appservice_double_puppet_enabled: true

Installing

After configuring the playbook, run the installation command: just install-all or just setup-all

Usage

When enabled, double puppeting will automatically be enabled for all bridges that support double puppeting via the appservice method.
