I'm trying to find inactive members in my GitLab-CE instance via the Gitlab API (v4).
One of the criteria for "(in)activity" is, whether a given user is member of any project or group.
While this information seems to be readily available via the webinterface (Groups and projects
tab on the user's overview page in the admin area), I cannot find that information via the API.
The only way i currently found is, to iterate over all projects (resp. groups) and check whether the user is member thereof.
This strikes me as very slow (as there are probably zillions of projects), so I'm looking for a more direct way to query the system for all projects where user
is member-of.
