Russ Alberry's fantastic pam_krb5 3.15 linked to above
Solaris 9 + MIT Kerberos + RA pam_krb5 works!
RHELv5 with stock MIT Kerberos + RA pam_krb5 works!
The setup above fails.
On the client side, I merely see "Permission denied."
instead of being asked to change my expired password.
If anyone has any ideas, I would love to hear them.
% ssh cairo
jblaine@cairo's password:
Permission denied, please try again.
