lsh doesn't honor password aging

[Thayne Harbaugh]

lsh doesn't seem to honor any password againg set
in /etc/shadow.  I imagine that this is because lsh
doesn't use pam (and we all know Niels opinion of that).

I find this a serious shortcoming because an admin
feels that they have locked-out a users with password
againg but the user is still able to log in - this
is a security hole.
