 ### Migrate the files and the database
 **Please note**: this is much more complicated than migrating only the files and also not as failproof so be warned!<br>
-Also, some special apps that e.g. implement custom user backends like the `user_sql` app will probably not work in Nextcloud AIO. Additionally, you will currently not be able to use local external storage in Nextcloud AIO since that is not supported, yet. See https://github.com/nextcloud/all-in-one/issues/76

 The procedure for migrating the files and the database works like this:
 1. Make sure that your old instance is on exactly the same version like the version used in Nextcloud AIO. (e.g. 23.0.0) If not, simply upgrade your former installation to that version or wait until the version used in Nextcloud AIO got updated to the same version of your former installation or the other way around.

 ### How to edit Nextclouds config.php file with a texteditor?
 You can edit Nextclouds config.php file directly from the host with your favorite text editor. E.g. like this: `sudo nano /var/lib/docker/volumes/nextcloud_aio_nextcloud/_data/config/config.php`. Make sure to not break the file though which might corrupt your Nextcloud instance otherwise. In best case, create a backup using the built-in backup solution before editing the file.
 
+### LDAP
+It is possible to connect to an existing LDAP server. You need to make sure that the LDAP server is reachable from the Nextcloud container. Then you can enable the LDAP app and configure LDAP in Nextcloud manually. If you don't have a LDAP server, yet recommended is to use this docker container: https://hub.docker.com/r/osixia/openldap/. Make sure here as well that Nextcloud can talk to the LDAP server. The easiest way is by adding the LDAP docker container to the docker network `nextcloud-aio`. Then you can connect to the LDAP container by its name from the Nextcloud container.

+### USER_SQL
+If you want to use the user_sql app, the easiest way is to create an additional database container and add it to the docker network `nextcloud-aio`. Then the Nextcloud container should be able to talk to the database container using its name.
