...se_session() and pam_sm_setcred() function in PAM module while OpenSSH hardcoded it "ssh". I made few changes in OpenSSh code so it can set terminal ID properly. These changes were : added do_pam_set_tty() in session_pty_req(Session *s) function in session.c and added do_pam_set_tty() in mm_pty_allocate() function in monitor_wrap.c It works fine for root and I get appropriate tty in pam_sm_cred() and pam_sm_close_session() function. But using same code, when I try to ssh through a non root account I am getting tty in pam_sm_close_session() but not in pam_sm_cred(). I am not sure why ssh is be...

...39;t make it to upstream yet. 1. "debug3: mm_answer_keyallowed: key %p is allowed" is always NULL, because it is freed before calling the log function. There is a flaw in logic of this debug log, when the key pointer is always null (it is ensured that it is freed before) the call. 2. mm_pty_allocate contains Dead code (if the second dup fails, it can't be different than -1) and comparison of the return dup() return value should be >=0 instead of >0 -- 0 is also valid FD. 3. process_server_config_line: sAuthorizedPrincipalsFile option handles intptr, without any possible label (th...

Hi folks, I came across this issue on both stock CentOS(v6.4) and Ubuntu(14.04 LTS) and was wondering if any of you have seen it. As far as I can tell this seems like a day-1 bug to me. PROBLEM: If I expire a linux user's password (passwd -e <user>) and then log in via ssh, it will prompt you for a password change. On changing the password successfully, sshd will drop the connection
