>Description:
pam_krb5 authenticates when I have it enabled in pam.d but it fails before storing a ticket in /tmp.  I have tracked it down so far to pam_set_data/pam_get_data.

Everything appears to be good and working in pam_sm_authenticate, I can pam_get_data after it's set perfectly fine.

But in pam_sm_setcred in pam_krb5, which gets called after pam_sm_authenticate completes, pam_get_data fails to retrieve it's ccache data and fails.

Now I'm stumped where to look.

>How-To-Repeat:
setup kerberos so you can kinit and kdestroy from a machine. Then on that machine enable kerberos through:

auth  sufficient pam_krb5.so  debug no_warn try_first_pass

Do this to login or ssh in the auth section.  Use a different password for kerberos so you know what is authenticating.  Use PAM_DEBUG versions of libpam.so.5 and pam_krb5.so.5 to see messages in /var/log/debug.log
