Invited a new user, see them in the administration -> users, but they do not show in the project under the people list. I also cannot assign them to a ticket.
* Atlassian administration -> Manage Users -> Click show details link for user:
Roles - Basic
* Click [. . .] -> View Jira project roles
My Project -> Service Desk Team - Enabled
