OpenSSH authentication broken on Leopard (PAM unable to create session)

OpenSSH's PAM module fails after authentication, preventing login.

Does this issue still exist? I don't have a Leopard system in use, so testing this would be impossible. If this bugs SL, too, then it would be nice to have steps to reproduce this behaviour in order to fix.
