Microsoft has released CRM 2015! In related news I thought I was losing my mind while I was setting up a test organization. I couldn’t find the User administration section. It’s been under Settings->Administration for quite a few releases now, but with 2015 it’s no longer there.
Instead, take a look at the Settings->Security section where you will find Users along with some other items that moved: Teams, Security Roles, Business Units, Field Security, and Access Team Templates. Some new features can be found here as well, including Hierarchy Security and Positions. Both of these will come in handy for better accommodating things like selective access for regional or departmental management teams.
