That is what PAM and BSD Auth are, wrapper APIs around things that
do authentication. I was suggesting that it is going overboard to
put a wrapper around two wrappers which will surely end up having
the compromises of both systems.

I do not see how wanting to be able to use 3rd party applications
is ``market-_focused_ reasoning''. Maybe you do not feel that it
is necessary to use anything that is not in basesrc, but many of
the rest of us actually appreciate the fact that NetBSD can compile
and run applications that were written on other UNIX systems.
Being able to do this follows from making a series of decisions
about adhering to standards that are commonly accepted by the UNIX
Do you think that providing POSIX compatibility is ``market-_focused_
reasoning''? Maybe it is... But I am quite glad that we have
decided to be `sale droid'-ish on that issue.

Greg, when you have provided BSD Auth client level support to all
of the things in pkgsrc that support PAM, e.g. gdm, kdm, xlock,
xscreensaver, and so on, then please by all means tell us how little
you care about 3rd party support for _our_ authentication mechanisms.
I have little desire to do that, and apparently you do not either
since I haven't seen any patches from you providing said support.
One of the big reasons to go with PAM or BSD Auth is to get NetBSD
out of the rather annoying situation that 3rd party applications
do not authenticate in the same way as the base operating system.

Yes, I probably don't care either. What I care about is the _clients_
will acutally authenticate in the same way as login(1).

Uh, SASL and PAM solve entirely different problems.

As I said above: put up the code for all the apps in pkgsrc and
get back to me.
