Most probably /etc/krb5.keytab got out of sync, i.e. someone called
ipa-getkeytab (or similar) without writing the result to
/etc/krb5.keytab. You can check this by calling
klist -k
and
kinit admin (or some other IPA user)
kvno host/ipa-01.int.domain.com(a)INT.domain.COM
if the key version number (kvno) from the kvno output cannot be found in
the klist output you have to write a fresh key to /etc/krb5.keytab with
ipa-getkeytab.
