Okay, now I see what you mean. You wan to be able to control the
permissions on the root directory of the mounted filesystem, not on the
autofs directory.

That's easy: For filesystems with ownership and permissions capabilities
(ext2, ext3, reiser, etc) the filesystem itself specifies the ownership
and permissions. For filesystems without ownership and permissions
capabilities (any of the FAT filesystems), use the appropriate options
to the mount command. man mount, and you probably want to use uid, gid
and umask.
