OpenSSH drop-in replacement

[Martin van Es]

Hi,

I'm looking for an OpenSSH drop-in replacement that fixes two problems
in OpenSSH for me:

1. Allow PAM_TEXT_INFO conversation messages displayed during
keyboard-interactive PAM authentication (without buffering). I don't
want a prompt, only display a url containing a challenge.
2. Honour new username after PAM set PAM_USER using
pam_set_item(PAM_USER, value)

Would dropbear be a valid contender?

Martin
