We have a server hosted instance of Confluence with 500 user licenses. Users cannot signup (Allow people to sign up to create their account is not checked) and any user addition is through admin only. I am the admin for my instance. Somehow, the user count goes up without my involvement. I had 426 users last night and in the morning user count went up to 431 and I made sure none of us in confluence-admin group added any users in the mean while. How is that posible?
Note: 1. our hosted confluence link has application link with our JIRA instance
2. We have several directories like Microsoft AD ( main user directory), JIRA interrnal Directory, XYZ directory etc. added under user directories in confluence. Please help.
