+# `finallycoffee.nextcloud.ldap-user-backend` ansible role
+
+Ansible role for managing LDAP authentication of nextcloud instances using ansible.
+
+## Prerequisites
+
+This role assumes a nextcloud instance is up and running, and has the `user_ldap`
+nextcloud app installed. For starting a nextcloud instance, see the
+`finallycoffee.nextcloud.server` role, for managing nextcloud apps see the
+`finallycoffee.nextcloud.apps` ansible role.
+
+## Configuration
+
+- Set `nc_ldap_api_method` to either `occ` or `http` to control wether the
+  configuration is set using `php occ` command line calls or the `http` API
+  of the `user_ldap` nextcloud app.
+
+- For `nc_ldap_api_method: occ`, ensure `nc_ldap_container` is set to the name
+  of the docker container where nextcloud is running, and `nc_ldap_occ_user` is
+  the user the container / nextcloud itself runs as. `nc_ldap_occ_command`
+  _can_ also be tweaked if `php` is not in the path, but the default should
+  be fine in most cases.
+
+- For `nc_ldap_api_method: http`, ensure `nc_ldapi_api_instance_url` contains
+  the URL to the nextcloud server, including protocol (and port, if
+  non-standard), and `nc_ldap_api_basic_auth_[user|password]` contain the
+  credentials of an admin user with the rights to edit the LDAP settings.
+
+- Set `nc_ldap_test_configuration` to `true`/`false` to have the role issue a
+  nextcloud-provided test of the configured LDAP configuration, this corresponds
+  to a `occ ldap:test-config <id>`.
+
+For most of the options, see the
+[nextcloud manual on configuration keys](https://docs.nextcloud.com/server/latest/admin_manual/configuration_user/user_auth_ldap_api.html#configuration-keys),
+the config keys are mapped 1:1 with a prefix of `nc_ldap_config_` and
+the so-called "snake-case" (`ldap_backup_host`), so `ldapUserFilterMode` becomes
+`nc_ldap_config_ldap_user_filter_mode`.

+# `finallycoffee.nextcloud.nginx-fpm-proxy` ansible role
+
+Ansible role for serving nextcloud static content and connecting to dynamic content via PHP-FPM.
+
+## Prerequisites
+
+A running nextcloud instance with FPM available either via IP+port or a unix socket.
+
+## Configuration
+
+- Set `nextcloud_nginx_data_path` to the data directory of the nextcloud instance,
+  from where static content etc is served from.
+
+- `nextcloud_nginx_storage_path` needs to be set to the storage path of the nextcloud
+  instance, where user data is stored. Usually this is `{{ nextcloud_nginx_data_path }}/data`.
+
+- Set `nextcloud_nginx_fpm_socket_dir` to the directory containing the FPM socket,
+  called `nextcloud.sock` by default. This can be overridden in `nextcloud_nginx_fpm_socket_path`.
+
+- If FPM is not used via a unix socket, set `nextcloud_nginx_fpm_server_ip` and
+  `nextcloud_nginx_fpm_server_port` accordingly. Note that the IP must be reachable
+  from inside the nginx container.

+
+> [!WARNING]
+> This role is not production ready or finished
+
+## Configuration
+
+Set `oidc_user_occ_user_oidc_provider_identifier` to a unique identifier.
+Populate your provider information in the `oidc_user_config_(settings_)`
+like this:
+
+```yaml
+oidc_user_config_identifier: my_provider
+oidc_user_config_discovery_endpoint: https://idp.example.com/
+oidc_user_config_client_id: my-client-id
