I think I know what this is.

When I was working with Microsoft on MS16-081 (which I discovered) they
told me that there was a bit of software that required machine accounts
to create other machine accounts.  I think this might be it.  (It made
the fix much harder). 

Either way, Samba doesn't support anyone other than an administrator
creating machine accounts (by default).  Some folks get around this
with ACLs, but take care, I would still treat any account that can
create new users as 'quite privileged'.
