openssh (OpenBSD) , bsdauth and tis authsrv
nuqneH,
I've tried using TIS authsrv authentication via bsd auth and found
it quite limited. The most important restriction it does not log
ip and fqdn of the remote peer, nor the application name, to
the authentication server. It does not matter much for TIS authsrv,
but since other applications do provide such information, our
authsrv version uses it for extra authentication restrictions.
