We have a community license with Atlassian and we started with JIRA. Then we added Confluence, and started to allow users to create accounts on Confluence to use Confluence Questions. The JIRA and Confluence users say "Directory: JIRA Server".
We're thinking about adding Stash possibly with public projects. What is the best way long-term to manage user accounts – should we continue to use JIRA Server, or something else (like Crowd)?
