When sshing into a machine with an expired password, the user is forced

the user is not advised if the proposed new password is in openldap's

why, even though openldap generates a reason/message and pam_ldap passes that
message to sshd (observed via strace).


What SSH software and version are you using?  If it's OpenSSH, there was
a bug regarding passing of PAM messages back to the client that would
probably explain your problem.  That bug was fixed in (from memory) 4.1p1.

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
