If it's visible to you, select the Users icon in the upper left.

Click the Search button (don't enter any names in the search field)

When the results appear, select the COMPUTERS column to sort (1 or 2 times) to see zero computers assigned to a username.

Thank you, I had thought as much - however - the entire list comes back with zero computers.  The correct number of users, but the computer column is zero for all of them

Did your users authenticate upon device enrollment? Are you able to manually assign a user to a computer at the device level?

@bfrench We don't use any automated enrollment, yet.  Local admin is manually created, then a local account with the short username of their network ID is created.  Sadly the machines are still bound.   Apologies @bfrench  - Not quite sure what you're asking.

If users do not authenticate against LDAP or cloud upon enrollment there is no user assigned to the computer unless you manually assign one.  A User in Jamf is not equivalent to a local account.

@bfrench Does that mean if they're not a mobile account?  These do connect via Kerberos extension - and NoMAD is used.

Jamf usernames and account usernames (local or mobile) are 2 different usernames.  A Jamf username assigned at enrollment or after would still exist after a computer is removed unless it is also removed.  A local/mobile account would no longer exist if the device that contained it was removed from Jamf.  To search for account usernames use the drop down in an inventory search.
