http://www.mindrot.org/~djm/openssh/openssh-newpam-20030123.tar.gz Is a snapshot of the new PAM-via-KbdInt authentication support from FreeBSD's OpenSSH tree. Please test this now. I can only surmise by the silence that has greeted my previous requests for testing that the code works perfectly. -d

...quot;; - What is supposed to be the behaviour of ssh when it is used with PAM ? Shall SSh pass on to PAM the exact credentials entered at the prompt (username and passwd) without affecting them (by putting "INCORRECT" in the passwd : buffer_put_cstring(&buffer, badpw); auth-pam.c in sshpam_respond() )? (BTW, this is how I have installed ssh on my linux box : ./configure --with-pam --prefix=/usr --sysconfdir=/etc/ssh make make install) - I found that other OpenSSH user had a similar problem. Is there a workaround ? Thank you for your help. I'm really struggling with this... ! Philip...

Hi. One thing that people seem to want to do with PAM is to deny a login immediately without interacting but return a message to the user. (Some platforms implement, eg, /etc/nologin via PAM this way.) Currently, sshd will just deny the login and the user will not be told why. Attached it a patch that return a keyboard-interactive packet with the message in the "instruction"

I added an EXPLICIT AuthenticationMethods publickey,keyboard-interactive + UsePam yes to sshd_config. Now, at connect attempt I get Password: Verification code: Password: Verification code: Password: ... I.e., It's asking for Password, not accepting pubkey AND when given the password (which is correct), and the GA VerificationCode, it simply repeats the credentials request.
