openssh conversation failure issue on HPUX
Openssh 5.0p1 on HPUX 11.23.

if they used publickey) then the sshpam_null_conv conversation function is still
used.

LinuxPAM and sshd: changing conversation function doesn't work but claims to.
...onnect with SSHv1 with an account that has an
expired password, the code above will be called, and the debug messages
will be sent to the client (since stdin/stdout is connected to the pty).
Here's the output from the client:

Despite pam_set_item claiming to succeed (it must have returned
PAM_SUCCESS otherwise fatal() would have been called), tty_conv is *not*
called by PAM, the previ...
