http://bugzilla.mindrot.org/show_bug.cgi?id=1028

           Summary: sshd does not forward non-query conversations to client
                    during pam auth
           Product: Portable OpenSSH
           Version: 4.0p1

                    May/023157.html
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: PAM support
        AssignedTo: openssh-bugs at mindrot.org
        ReportedBy: dleonard at vintela.com


When a PAM auth module calls through the pam_conv to display a non-prompt
message just before it returns PAM_AUTH_ERR,  sshd gets the message text and
appends it to a banner buffer to be sent later at session startup.

The problem is that because authentication fails, the buffer is never sent,
meaning the important message from the auth module never makes it to the user
client.
