# Setting up matrix-ldap-registration-proxy (optional) The playbook can install and configure [matrix-ldap-registration-proxy](https://gitlab.com/activism.international/matrix_ldap_registration_proxy) for you. This proxy handles Matrix registration requests and forwards them to LDAP. **Please note:** This does support the full Matrix specification for registrations. It only provide a very coarse implementation of a basic password registration. ## Quickstart Add the following configuration to your `inventory/host_vars/matrix.DOMAIN/vars.yml` file: ```yaml matrix_ldap_registration_proxy_enabled: true # LDAP credentials matrix_ldap_registration_proxy_ldap_uri: <URI> matrix_ldap_registration_proxy_ldap_base_dn: <DN> matrix_ldap_registration_proxy_ldap_user: <USER> matrix_ldap_registration_proxy_ldap_password: <password> ``` If you already use the [synapse external password provider via LDAP](configuring-playbook-ldap-auth.md) (that is, you have `matrix_synapse_ext_password_provider_ldap_enabled: true` and other options in your configuration) you can use the following values as configuration: ```yaml # Use the LDAP values specified for the synapse role to setup LDAP proxy matrix_ldap_registration_proxy_ldap_uri: "{{ matrix_synapse_ext_password_provider_ldap_uri }}" matrix_ldap_registration_proxy_ldap_base_dn: "{{ matrix_synapse_ext_password_provider_ldap_base }}" matrix_ldap_registration_proxy_ldap_user: "{{ matrix_synapse_ext_password_provider_ldap_bind_dn }}" matrix_ldap_registration_proxy_ldap_password: "{{ matrix_synapse_ext_password_provider_ldap_bind_password }}" matrix_ldap_registration_proxy_systemd_wanted_services_list_custom: - matrix-synapse.service ```
