Yes, but have you ever tried to create a file owned by uid adm? At the
fs console use fs(8) "create file adm adm 664" says invalid uid!
According to the docs, a negative id simply means that the file server
will not allow anybody to authenicate to that id. So the only way to
create such a file is from the fs console, but as above, you can't.
