It means that the pam_krb5 auth stack either never ran or failed, and
therefore setcred and open_session will be skipped.  pam_krb5 only does
ticket cache setup if pam_krb5 was the one doing the authentication.

If you're doing GSSAPI authentication to sshd, this is normal, since sshd
does ticket cache setup itself in that case and pam_krb5 doesn't need to
do anything.
