The new version of glibc removes support for NIS and NIS+. The default
/etc/nsswitch.conf file provided by
filesystem package already reflects this change. Please make sure to merge pacnew file if it exists prior to upgrade.
NIS functionality can still be enabled by installing
libnss_nis package. There is no replacement for NIS+ in the official repositories.
pam 1.3.0-2 no longer ships pam_unix2 module and
pam_unix_*.so compatibility symlinks. Before upgrading, review PAM configuration files in the
/etc/pam.d directory and replace removed modules with
pam_unix.so. Users of pam_unix2 should also reset their passwords after such change. Defaults provided by
pambase package do not need any modifications.
