It seems with a recent release of Confluence the available names that show up in the auto-complete of the share functionality have greatly increased. I believe in the past the share was limited to users in the confluence-users group. Now, it seams that every user in the system is being shown as a suggestion. We use Active Directory to pull in hundreds of users but only a limited amount have access to Confluence and in the confluence-users. I'd like to suppress the auto-complete of users in the share feature to those only in the confluence-users group.
