Hey folks! PAM has finally landed in /testing. Some here wanted it to go
right into the main tree immediately, and in a more normal development cycle
I'd have been inclined to agree (it is -current, after all). But it's
probably better for it to appear in /testing first, to make sure we didn't
miss any bugs and also to serve as a warning shot that we'll be shaking up
the tree pretty good over the next few weeks. I'd like to see this merged
into the main tree in a day or two, so any testing is greatly appreciated.
Switching to the PAM packages (or reverting from them) is as easy as
installing all of them with upgradepkg --install-new, and if reverting then
remove the three leftover _pam packages. After reverting, a bit of residue
will remain in /etc/pam.d/ and /etc/security/ which can either be manually
deleted or simply ignored. While there are many more features available in
PAM compared with plain shadow, out of the box about the only noticable
change is the use of cracklib and libpwquality to check the quality of a
user-supplied password. Hopefully having PAM and krb5 will get us on track
to having proper Active Directory integration as well as using code paths
that are likely better audited these days. The attack surface *might* be
bigger, but it's also a lot better scrutinized.
Thanks to Robby Workman and Vincent Batts who did most of the initial heavy
lifting on the core PAM packages as a side project for many years. Thanks
also to Phantom X whose PAM related SlackBuilds were a valuable reference.
And thanks as well to ivandi - I learned a lot from the SlackMATE build
scripts and was even occasionally thankful for the amusing ways you would
kick my ass on LQ. ;-) You're more than welcome to let us know where we've
messed up this time.
The binutils and glibc packages in /testing were removed and are off the
table for now. I'm not seeing much upside to heading down that rabbit hole
at the moment. Next we need to be looking at Xfce 4.14 and Plasma 5.18 LTS
and some other things that have been held back since KDE4 couldn't use them.
Cheers! :-)
