Just to confirm, this is with master?

I think there are some open bugs for useradd issues like this. It is
supposed to work but sounds like there are races. If there isn't a bug
open for it, there probably should be.

Sadly we don't have many people interested in working on issues like
this so I can't say when it might get fixed, we do our best!
