Windows seems only to allow Administrators to do NetShareEnumAll while Samba seems to allow anyone to do that

OK, it seems to be more complex that I thought. There is an article
from 2005 called "How to allow users to manage file and print shares
without granting other advanced privileges" that addresses this.

A stop-gap that will make things work reasonably would be to insist
that they must have SeDiskOperatorPrivilege ... I will look at that
first and think more about the other stuff.
