Could you please stay on topic and explain if you can why ktutil can't be used as described in https://kb.iu.edu/d/aumh?
Does ipa makes ktutil not functional?
Can you show output of

kinit admin
kvno admin
klist -ef

I suspect your admin password did change over time so it has a different
kvno value than what you have used in ktutil's addent (-k 1).


I modified a script posted on https://stackoverflow.com/questions/37454308/script-kerberos-ktutil-to-make-keytabs to create a simple test case:

#!/bin/bash
user=admin
read -sp "${user}'s pass:" pass
echo
kinit $user
KVNO=$(kvno "$user" | awk '{print $NF}')
ETYPE=$(klist -ef | grep -A 1 krbtgt | tail -1 | awk '{print $NF}')
printf "%b" "addent -password -p $user -k $KVNO -e $ETYPE\n$pass\nwrite_kt $user.keytab" | ktutil
printf "%b" "read_kt $user.keytab\nlist\nquit\n" | ktutil
kinit -k -t $user.keytab $user


The result when ran from an IPA host is the same error as before: kinit: Preauthentication failed while getting initial credentials despite the fact that KVNO numbers match. Could anyone confirm that admin keytab acquired via ipa_getkeytab is working and if yes then what is the difference from above method?

ipa-getkeytab works for me, I don't know why ktutil isn't working but we do zero testing using this.
