There must be some kind of configuration difference then, because it
does not happen under 4.0F for me.  With OpenSSH 2.3.0p1 on 4.0F, I get:

$ ssh dns
Account is disabled -- see Account Administrator.

Connection to dns closed.

This is the same thing that rsh returns.

There is a problem with OpenSSH 2.5.1p1 that I need to look at:

$ ssh fly
Connection to fly closed by remote host.
Connection to fly closed.

It should report that the account is disabled like 2.3.0p1.

I don't get that behavoir either - "Last   successful login" reflects
the last _successful_ login; the attempt to login to a locked account
fails and that time is reflected in "Last unsuccessful login".

I did just realize that I had ".hushlogin", so I did not get the MOTD.
D'oh!  I do now get the MOTD, even on locked accounts.  I will look into
this.  I still do not get my last login times printed.

I will look at this some more.

I don't speak for anybody but myself - that's enough trouble.
