Description of problem:
I have same passwords in /etc/shadow and in krb5. I use this config:

password required /lib/security/$ISA/pam_unix.so nullok
use_authtok md5 shadow
password required /lib/security/$ISA/pam_krb5.so use_authtok
Changing password for user luf.
Changing password for luf
(current) UNIX password:
passwd: Authentication failure
pam_krb5 doesn't use typed password used in pam_unix. I see same
problem in older versions and in CVS too.

5. login as the user and type passwd
Actual Results: see Description
