Oh, and one more note, tinylogin addgroup is not working. It has the addgroup argument parsing error, thus sshusers group cannot be created automatically from init/install scipts from the add-on.
# tinylogin addgroup user
Tinylogin v1.4 (2010.08.23-10:11+0000) multi-call binary
Usage: addgroup [OPTIONS] <group_name>
