I would like the ability to put up my own custom "welcome page". This
would be intended for new users who log in for the first time. Perhaps I
could put instructions on how to get started, or request access to an
organization. This is important because I have an external AD server that
creates the user upon first login, so there is little opportunity to
pre-authorize into an organization, or as a role.
I would start with:
[root@foreman]# locate login.html.erb
<https://github.com/theforeman/foreman/blob/master/app/views/users/login.html.erb>
