Yeah, I was also looking around for a command-line tool that will allow
me to test authentication against PAM. Neither of the two tools I could
find on the 'net (pamck and pamauth) seem to be easily available,
keeping on looking.
As a last resort one could use direct auth against {passwd,shadow}, but
that would be absolutely the last resort. I'd rather make a Perl PAM
script that does that before going into grep & co!
