Currently if LDAP is used as an auth provider, each LDAP user has to first login once into OpenProject until his user shows up when trying to add a member to a project.
I am referring to the `/projects/demo-project/members/new` page.
If the checkbox for create users on-the-fly is selected in the LDAP settings, it would be great if all users from that source would show up in the dropdown and if the user has never logged into that OpenProject instance, it would then be created on the fly. This would remove the somewhat strange step for new OpenProject users to login to it just to be able to get added to a project and thus helps project admins to pre-setup the projects better.

I can probably contribute there if I get some help and pointers where that code is :-)

Thanks,
Johannes
