I have a wierd issue. I have form-based auth working. It seems that when the server process is NOT shutdown cleanly (as opposed to using shutdown.sh or equivalent) the next time the server runs form-based auth doesn't accept any login attempts. If I delete the contents of the work/ and tmp/ dirs and relaunch the server, auth works again.
The reason I am killing the process in such a manner is that I'm running the server within eclipse sometimes and just terminating the process from within there.
It's mainly an annoyance, but I'd like to understand the problem if someone out there knows why this would be occuring.
