#1716 investigate non working gssapi/kerberos auth passthrough on id.centos.org
Closed: Fixed with Explanation by arrfab. Opened by arrfab.

since DC move (Fedora migration to rdu3) and new ipsilon instance rolled-out next to new Fedora IPA servers, we can auth through id.centos.org but transparent gssapi/kerberos auth doesn't work.
Spent some time on this last Friday but need to work again to verify things and details so creating ticket for awareness and status update in this ticket

identified missing Service Principal alias for id.centos.org (public hostname) versus real fqdn that is enrolled in IPA.
Added new SP alias on top of existing one (so that's working on real name but also alias) and dowloaded new keytab.
Working after that (from laptop with valid ticket, and so externally) :
