I'm not a great expert in the draft specs for SSH, however this is the
behavior I see from my server except for one thing. I'm running
F-SECURE 3.2.0 and whenever my password expires, I'm prompted to change
it. However I'm curious as to why you're getting insufficient
privilege for SYS$INPUT. Your banner (I assume you're talking about
the SYS$WELCOME logical) would display after this point. You may want
to look through your login.com or the system defaults for a login that
may be calling something required for an interactive session when
changing the password isn't technically an interactive session yet.
From my experience you should login, get prompted to change the
password by the VMS authentication subsystem and then get disconnected
and then have to login again. My theory is that VMS lacks the proper
hooks to fully support the SSH spec for dealing with
SSH_MSG_USERAUTH_PASSWD_CHANGEREQ so they're trying to make it behave
more like telnet. If no one else on this list knows a better answer,
you might want to try the Process' Listservs. Hunter Goatley is an
hold VMS hand who was very helpful at answering some NFS questions
about a year ago for me.
