Most of you are probably aware of this setting because it has been available in previous versions of Kentico (4.0/4.1). But for those that don't, you can share user accounts and allow the user to login on all sites. To enable this feature, go to "Site Manager" and open up the "Settings" tab, select "global" for site and click on the "Membership" tab. Finally check the box for the "Shared user accounts" setting.
