Here's one that someone wrote for 386BSD, it's what I've been using. I
suppose we should disttribute one with the next release? Note that it
was not written by me and I've no idea who bmyers is. Also, I've
occasionally had problems with it not writing an entry to the passwd
file. No idea why but just retrying usually fixes it.
