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.
