The script mentioned in comment 9 has served us well for the past 3+ years and is "maintained" on https://github.com/cedric-dufour/custom-conf/tree/master/generic/all/custom-conf-pam-krb5/usr/share/custom-conf-pam-krb5/config/etc/security/pam-script.d as part of our "standard" Kerberos/PAM configuration.
