LDAP/Kerberos Issue

I am getting the following error message when trying to login to the client:

while verifying tgt[Unknown code ____ 255]

If I move the /etc/krb5.keytab out of /etc, it works fine. This is HP-UX v23

Does anyone have any ideas?

Getting this error when try'ing login as myself:
login: while verifying tgt[Unknown code ____ 255

Without the /etc/krb5.keytab, it works fine. This is on HP-UX v23,
needed modifications in the /etc/pam.conf, basically just repointing
krb5 shared libraries, that has been done. Can anyone please help with
this?
