Uid checking became more strict in fuse-2.3.  See the changelog entry
for 2005-04-28:

    * Make checking of permission for other users more strict.  Now
    the same privilege is required for the mount owner as for ptrace
    on the process performing the filesystem operation.

This makes some setuid programs fail on fuse mounts.

I don't understand the question.  What do you mean by "use"?
