Jira is handling the user management for our set up. Once a user is given access to Jira, they will also have access to confluence. I noticed that we couldnt @ some users in confluence. Then I noticed that none of these users are in the confluence people directory. But they all appear in Confluence -> User Management. Also, they all have access to Confluence spaces and cant edit spaces and what not. But for some reason they arent appearing in the people directory and cant @ them.
