I'm running Solaris 10 Update 4, and when using Russ' pam_krb5 on a
principal whose password has expired, I see the following in the debug
log:

|Jan 20 11:52:03 login sshd[10303]: [ID 584047 auth.debug] (pam_krb5): cah220: 
attempting authentication as cah220 at COYHILE.COM

|Jan 20 11:52:05 login sshd[10303]: [ID 584047 auth.debug] (pam_krb5): cah220: 
<unknown>: exit (failure)

For what it's worth, I've got the following in my pam.conf on this box:

# grep sshd-kbdint pam.conf
sshd-kbdint     auth requisite          pam_authtok_get.so.1
sshd-kbdint     auth required           pam_dhkeys.so.1
sshd-kbdint     auth required           /tmp/pam_krb5.so.1 debug
sshd-kbdint     auth optional           pam_unix_auth.so.1
sshd-kbdint     session required /tmp/pam_krb5.so.1 debug

Am I running into SEAM just not supporting "hey bozo, you're password is
expired, change it now", or did I hork the configuration somehow.

If you want, I can also provide the sshd_config.

I appreciate any help you can give with this; I'm still a bit of a
novice when it comes to doing anything cute.  Along the same lines, is
there any way to bounce back something like "Your password is going to
expire in n days" during the authentication process? (say only if n <
10).  Actually strike that.  Is there some easy way to write an app
that you'd run from /etc/profile to banner that sort of information? If
I were using normal UNIX auth, I could do that relatively easily using
the information in the shadow file.
