Looks like the hostname is "localhost" on the ppc64.
Did you miss a step?

Recently I decided to play around with some alternative architectures on fedora
with virt-manager/qemu. So I set up some power machines. (ppc64 and ppc64le)
I also made some arm machines but I gather openafs isn't quite ready yet for
arm in 1.6.22.2.
I was able to compile openafs rpms for ppc64. I did not try ppc64le yet. Its very slow to build in a emulator. Surprisingly openafs builds and I am able to start the service and list afs directories.
But I can't authenticate to kerberos like I can on x86_64. I feel like I'm missing something basic but I'm unsure what it is.
When I run kinit on x86_64, I get
[gsgatlin@t540p ~]$ kinit gsgatlin

Notice the default principal says @EOS.NCSU.EDU <http://EOS.NCSU.EDU> instead of
[email protected] <mailto:[email protected]> like it did on x86_64.
So when I run aklog on ppc64 it fails
[gsgatlin@localhost bin]$ aklog -d -c eos.ncsu.edu <http://eos.ncsu.edu> -k

Here is a link to my /etc/krb5.conf file on both systems:
https://pastebin.com/3HHP15c0
Does anyone know why it would work on one architecture (x86_64) but fail on another (ppc64) ? Is my /etc/krb5.conf missing something? kinit is provided by red hat so I think I can't have messed up
that particular binary.
[gsgatlin@localhost bin]$ which kinit
/usr/bin/kinit
[gsgatlin@localhost bin]$ rpm -qf /usr/bin/kinit
krb5-workstation-1.15.2-7.fc27.ppc64
Thanks a lot for any ideas anyone may have. I feel like I was close to getting
everything working.
