To ensure maximum discovery, you can make your identity server also forward lookups to the central matrix.org Identity server (at the cost of potentially leaking all your contacts information).
Enabling this is discouraged and you'd better [learn more](https://github.com/ma1uta/ma1sd/blob/master/docs/features/identity.md#lookups) before proceeding.
To use the [Registration](https://github.com/ma1uta/ma1sd/blob/master/docs/features/registration.md) feature of ma1sd, you can make use of the following variables:
-`matrix_synapse_enable_registration_captcha` - to validate registering users using reCAPTCHA, as described in the [enabling reCAPTCHA](configuring_captcha.md) documentation.
- variables prefixed with `matrix_nginx_proxy_proxy_matrix_3pid_registration_` (e.g. `matrix_nginx_proxy_proxy_matrix_3pid_registration_enabled`) - to configure the integrated nginx webserver to send registration requests to ma1sd (instead of Synapse), so it can apply its additional functionality
-`matrix_ma1sd_configuration_extension_yaml` - to configure ma1sd as required. See the [Registration feature's docs](https://github.com/ma1uta/ma1sd/blob/master/docs/features/registration.md) for inspiration. Also see the [Additional features](#additional-features) section below to learn more about how to use `matrix_ma1sd_configuration_extension_yaml`.
[Authentication](https://github.com/ma1uta/ma1sd/blob/master/docs/features/authentication.md) provides the possibility to use your own [Identity Stores](https://github.com/ma1uta/ma1sd/blob/master/docs/stores/README.md) (for example LDAP) to authenticate users on your Homeserver. The following configuration can be used to authenticate against an LDAP server:
What this playbook configures for your is some bare minimum Identity Server functionality, so that you won't need to rely on external 3rd party services.
To learn more about how to do this, refer to the information about `matrix_ma1sd_configuration_extension_yaml` in the [default variables file](../roles/matrix-ma1sd/defaults/main.yml) of the ma1sd component.
If your use case requires mobile verification, it is quite simple to integrate ma1sd with [Twilio](https://www.twilio.com/), an online telephony services gateway. Their prices are reasonable for low-volume projects and integration can be done with the following configuration:
If you want open all domains, you have to setup the allowed variable under policy, which is the return value if nothing else did match (white- and blacklist). But be aware, you cant block toplevel domains (aka .xy) because the internal architecture of ma1sd didnt allow that.
If email address validation emails sent by ma1sd are not reaching you, you should look into [Adjusting email-sending settings](configuring-playbook-email.md).
