We've recently setup a Jira Software/Confluence install on a dedicated server hosted with a Cloud provider, however to have a smooth login experience for our internal staff we'd like to link this to our Active Directory. This would all be possible if we created/moved a domain controller to the DMZ, however is this possible without having to do that? E.g. have an authentication page internally that users login to, which then forwards to our externally hosted Jira?
