pam (1.1.3-1ubuntu3) UNRELEASED; urgency=low
+ [ Steve Langasek ]
* debian/patches/pam_motd-legal-notice: use pam_modutil_gain/drop_priv
common helper functions, instead of hand-rolled uid-setting code.
+ [ Martin Pitt ]
+ * debian/local/common-session{,-noninteractive}: Enable pam_umask by
+ default, now that the umask setting is gone from /etc/profile.
+ (LP: #253096, UbuntuSpec:umask-to-0002)
+ * debian/local/pam-auth-update: Add the new md5sum of above files.
+ * Add debian/patches-applied/pam_umask_usergroups_from_login.defs.patch:
+ Deprecate pam_unix' 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.
+ (Closes: #583958)
