FYI, pam_limits as is doesn't compile on Solaris, but it doesn't take
much to make it happen; I sent the originator a patch. Some of the
rlimits on Linux don't exist on Solaris, but priority and other non-rlimit
stuff, as well as rlimits present on Solaris, should be ok, although I've
only tried priority. core file limits, and limits on maximum login sessions
per user so far.
