changes in pam: automatic configuration of PAM modules
 
Dear developers,

I'm happy to announce that with the latest upload of pam to unstable, we at
last have an interface that allows both automatic and interactive
configuration of system authentication, using that staple of the Debian
system, debconf.

It's unfortunate that this wasn't ready to go in time for the lenny freeze,
but in the meantime the new design has been getting some exercise in Ubuntu,
so the integration into unstable should be fairly painless - sorry to
disappoint the bleeding edge masochists. :) You can read the
pam-auth-update(8) manpage for an explanation of the tool itself.
Maintainers of PAM modules that would want to make use of this interface
should also read <https://wiki.ubuntu.com/PAMConfigFrameworkSpec>,
much of which will eventually find its way into the package as developer
documentation.

As a result of the prototyping work done on this within Ubuntu, patches are
already available for several module packages (libpam-krb5, libpam-ldap,
libpam-smbpass, ecryptfs-utils, libpam-ck-connector) which I will work on
submitting to the Debian maintainers over the next week or so. If
maintainers of other PAM module packages have questions about implementing
pam-auth-update support, I'm happy to assist - and of course if you find the
documentation lacking, suggestions for improvement are welcome.

Cheers,

Hello,

Interesting development.

Is there any possibility of getting this to work with the following
packages?


* libpam-ccreds (see
<https://bugs.launchpad.net/ubuntu/+source/libpam-ccreds/+bug/294977>)

* libpam-cracklib

Thanks

Yes.

Already implemented, since this package is built from pam source.

I have updated the libpam-ck-connector with todays upload of 0.3.0-1 and
included the patch from Ubuntu. So you can cross me of this list ;-)

Cheers,
Michael

Could this also be used to automatically setup gnome-keyring?

Cheers,

Probably not, because gnome-keyring's PAM module isn't generally applicable
and shouldn't be used for all services. You probably only want this module
used by gdm, gnome-screensaver, and maybe a handful of others - you don't
want the module triggering on every POP connection, web authentication, etc.

On the other side Gnome keyring is usually used on desktop and most
people do not run much servers which authenticate against PAM there.
I've always used gnome-keyring from common PAM configuration and never
had problems with that.

And since it’s an optional module, it works fine this by only setting it
up for gdm and gnome-screensaver.

However, the password stanza is applicable to all password services, so
that’s where the new configuration system will be needed.
