User creation and authentication on GitLab / LDAP
When a user registers, he should get a record that is accessible to GitLab and, in case he's a paying member, provide him with access to the Ecobytes group (see https://lab.allmende.io/ecobytes/community/issues/39).
Whether this is happening via the GitLab API, or by directly mapping the users to the LDAP Schema is to be assessed.
