As an FYI on a head-scratcher for my fellow JAMF'ers. I created an extension attribute based on local users. JAMF already inventoried the data, but not in a usable format for my needs. My EA was called "Local Users" using a script found on JAMF Nation. My Smart Group was based on matching specific criteria - in this case the logic was "is not: No Local Users"
Strangely it was reporting every single workstation in our environment was a member of this group (which they aren't). My EA was reporting properly, but apparently the Inventory Item of Local User Accounts was also populating a record, even though the EA was specifically chosen as criteria.
Changing the name of the EA from "Local Users" to "Prohibited Local Users" resolves this. I assume that my EA and the JAMF Inventory Item having similar names was the root of this based on the way a smart group reads the database. JAMF Support was as perplexed by this as I was, and only during a webex with them did I think this could be the cause of my issue and change the name, which resolved this. I'm curious if others have experienced this or not and I just happened to stumble upon this.
