pam (1.4.0-11ubuntu1) jammy; urgency=medium
* Merge from Debian unstable, remaining changes:
- debian/control: have libpam-modules recommend update-motd package
- debian/libpam-modules.postinst: Add PATH to /etc/environment if it's
not present there or in /etc/security/pam_env.conf. (should send to
Debian).
- debian/libpam0g.postinst: only ask questions during update-manager when
there are non-default services running.
- debian/libpam0g.postinst: check if gdm is actually running before
trying to reload it.
- debian/patches-applied/ubuntu-rlimit_nice_correction: Explicitly
initialise RLIMIT_NICE rather than relying on the kernel limits.
- debian/patches-applied/pam_umask_usergroups_from_login.defs.patch:
Deprecate pam_unix's explicit "usergroups" option and instead read it
from /etc/login.def's "USERGROUP_ENAB" option if umask is only defined
there. This restores compatibility with the pre-PAM behaviour of login.
- debian/patches-applied/pam_motd-legal-notice: display the contents of
/etc/legal once, then set a flag in the user's homedir to prevent
showing it again.
- debian/update-motd.5, debian/libpam-modules.manpages: add a manpage
for update-motd, with some best practices and notes of explanation.
- debian/patches/update-motd-manpage-ref: add a reference in pam_motd(8)
to update-motd(5)
- debian/local/common-session{,-noninteractive}: Enable pam_umask by
default, now that the umask setting is gone from /etc/profile.
- debian/local/pam-auth-update: Add the new md5sums for pam_umask addition.
- debian/patches-applied/extrausers.patch: Add a pam_extrausers module
that is basically just a copy of pam_unix but looks at
/var/lib/extrausers/{group,passwd,shadow} instead of /etc/
- debian/libpam-modules-bin.install: install the helper binaries for
pam_extrausers to /sbin
- debian/rules: Make pam_extrausers_chkpwd sguid shadow
- Add lintian override for pam_extrausers_chkpwd
- Disable custom daemon restart detection code if needrestart is available
- d/libpam-modules.postinst: Add /snap/bin to $PATH in /etc/environment
* Dropped changes, included in Debian:
- d/p/pam_env-allow-environment-files-without-EOL-at-EOF.patch:
Allow /etc/environment files without EOL at EOF.
