I have a client I want to be able to view and comment on issues on their project only (all other developers should be able to access this project, as with all other projects). I have created a user, created a group for just this project-user, created a permissions scheme with one entry, allowing the user to Browse Projects, and in Project Roles have this user enabled with the Developers and Users checkboxes (and not the Administrators checkbox).
But when I log in as this user, I get a mostly empty dashboard and at the top right it says "Log In". I click that and the page just reloads the same - can't seem to "log out" (if I am logged in) without closing the page and clearing cache, nor to "log in" since when I do so it seems I am not logged in.
Previously I tried adding the user to the Users group, but that let them see all projects.
What else do I need to do? Is there a step-by-step for this - it's very confusing.
