ssh's pam support is somewhat broken.

yes stable will give you a `Permission denied' if the password is
expired, it will not allow you to change it.  Wichert filed the
original bug a long time ago, it was marked fixed, i found it was
certainly not fixed and reopened, where it collected dust for the
better part of a year before Christian Kurz finally got it fixed (i
just remembered this happened about two months ago or so, i never
tested it).

the fix is only in OpenSSH 2 and not 1.2.3 which is in stable.

no plain password expiration, and i ensured i did it right by logging
into the console with this user and i indeed was allowed to login and
was forced to change the password, tried the same with ssh ->
Permission denied.  

your example does prove that the ssh in unstable is finally fixed, but
that does no good for stable users until this fall most likely.
unless they build the unstable ssh.
