@ -13,18 +13,21 @@ Add the following configuration to your `inventory/host_vars/matrix.DOMAIN/vars.
```yaml
matrix_ldap_registration_proxy_enabled: true
```
That is enough if you use the synapse external password provider via LDAP.
If you want to use your own credentials add the following to your `inventory/host_vars/matrix.DOMAIN/vars.yml`:
# LDAP credentials
```yaml
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>
```
TODO: is the block above correct? Else indicate that it can only be used with the LDAP password provider for Synapse
If you already use the [synapse external password provider via LDAP](docs/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 }}"
```
