Provide Documentation for Drupal

[obel1x]

Hi, can anyone please provide a short documentation for integration with Drupal in Readme, as this seems to works as of #66 .
Maybe @mlojewski-me , as you did it already? Thx and hf!

Not sure if sql_user works for Drupal. At the moment the requirements in the setup are spread in Drupal database various tables and columns not ONLY ONE user table. By testing with the fields which exist in Drupal SQL db the user import only syncs display names without any credentials or e-mail addresses. I am sure Nextcloud would get a massive developer and contribution amount woosh from Drupal developers if both systems would integrate in each other. I know that there where already attempts for Drupal modules connecting to Nextcloud in the past. And since Drupal is rather a building system often used for more complex systems rather than for simple websites it could be a perfect combination of bot to create team spaces with wikis etc.

This app works for users. I have used it for some years now. The Drupal users table is the main and only one you need.

Only recent changes to the uid/username might give some trouble. See #137 (comment) for a basic setup.

The group mapping may not work at the moment, at least if you are using Organic Groups. I cannot say if Groups might work.
