Hi Brian,
I'm sorry it took so long to reply to you, but you haven't been forgotten! I've set up kerberos using freeipa on my own test system but I haven't been able to reproduce the bug you're seeing. I had it working by using my kerberos domain set in /etc/idmap.conf and I saw the new domain go over the wire when I changed it in idmap.conf. Do I need to do anything more to mimic your setup?
