That error message means that when pam_krb5 attempted to verify the
Kerberos authentication by checking a service ticket obtained with the TGT
against your local keytab file, it was able to read the keytab file but
checking the service ticket failed.

Things to check:

* Does /etc/krb5.keytab (or whatever KRB5_KTNAME is set to in the
  environment) have a reasonable principal and key in it?  Generally, it
  should be host/<system>.

* Is that the current key?  The most common cause of this problem is an
  outdated keytab for a principal whose key has since changed.

* Can you obtain tickets using that keytab file with:

      kinit -k -t /etc/krb5.keytab <principal>

  where <principal> is whatever you have keys for there (klist -k will
  show you)?  If so, that should verify that the keytab isn't out of
  date.
