pam_tally does it in a flat file on-disk. It's not perfect, but it
works. It'd be good enough for me if there was a hook in the right
place that I could write the contrib module.
Of course, it'd be even nicer to have support for this in-core, since
it's a FISMA requirement and not everyone is going to like having to
install a contrib module to handle something like this. Of course, so
is stuff like remembering old passwords, password aging, etc... I do
really wish there was a way PAM could be used by applications
*independently* of the system auth (eg: /etc/passwd) to handle all of
this. If anyone's aware of a way, I'm all ears..
Thanks,
Stephen
