auth-pam.c support for pam_chauthtok()
When we installed OpenSSH 2.1.1p4 on our Solaris systems, our users noticed that it did not honor password expiration consistently with other Solaris login services. The patch below is against OpenSSH 2.2.0p1 and adds support for PAM password changes on expiration via pam_chauthtok(). A brief summary of changes: auth-pam.c: * change declaration of pamh to "static pam_handle_t *pamh",

pam problems with securid patch
Hi, I have the securID patch applied to openssh3.4p-1 and it's compiled with pam. The problem I'm getting is that SecurID auth works OK, but normal password auth doesn't. I narrowed down the failure to the following section in auth-pam.c : __pampasswd = password; pamstate = INITIAL_LOGIN; pam_retval = do_pam_authenticate( options.permit_empty_passwd ==

TISviaPAM patch
Here is a patch that does TIS auth via PAM. It's controlled by a switch in the sshd_config. You'd use it by having a PAM module that sets PAM_PROMPT_ECHO_ON. eg, you could use it with pam_skey or pam_smxs. The patch is against the 2.9.9p2 distribution. I'm not on the list, a reply if this patch is accepted would be great. (But not required, I know some folks have a distaste for

[PATCH] PAM chauthtok + Privsep
Hello All. Attached is an update to my previous patch to make do_pam_chauthtok and privsep play nicely together. First, a question: does anybody care about these or the password expiration patches? Anyway, the "PRIVSEP(do_pam_hauthtok())" has been moved to just after the pty has been allocated but before it's made the controlling tty. This allows the child running chauthtok to

[PATCH #9] Password expiration via /bin/passwd.
This is an attempt to simplify the AIX expiry-via-passwd stuff and make it more generic. (There's actually a net reduction in #ifdefs). Patch against CVS: 1) configure finds passwd. 2) sshd uses passwd during session if required. 3) sshd uses passwd for PAM change if privsep disabled. 4) sshd uses Buffers for expire and post-login messages (no longer AIX specific). 5) password_change_required

[PATCH] Password expiry with Privsep and PAM
Hi All. Attached is a patch that implements password expiry with PAM and privsep. It works by passing a descriptor to the tty to the monitor, which sets up a child with that tty as stdin/stdout/stderr, then runs chauthtok(). No setuid helpers. I used some parts of Michael Steffens' patch (bugid #423) to make it work on HP-UX. It's still rough but it works. Tested on Solaris 8 and

HP-UX PAM with Trusted System patch
I'm fairly new to the list and new to submitting patches. Can someone please verify the attached patch for running a HP-UX Trusted System with PAM and OpenSSH 3.4p1? The problem seemed to be that pam couldn't verify the user via __pamh after the call to permanently_set_uid in session.c. So I called do_pam_session prior to the call and added a function do_pam_set_tty in order to set the

patch for TIS (skey/opie) *and* passwd auth via PAM
Hello, appended is a patch that makes it possible to use PAM both for password authentication and TIS (i.e. s/key or opie or any other interactive challenge/response scheme). I have developed this starting from the patch at http://www.debian.org/Bugs/db/61/61906.html on Debian with openssh-2.1.1p4-3. After configuring ssh with --with-pam-tis, there are two PAM services, "sshd" and

3.2.3p1/auth-pam.c: PAM_PROMPT_ECHO_OFF in INITIAL_LOGIN pam state
I have been unable to use any challenge/response based pam module (eg. pam_opie.so) for ssh authentication, because the challenge (needed to compute an appropriate response) is never shown during login. do_pam_conversation() in auth-pam.c will not print any prompts while in the INITIAL_LOGIN state, queueing them for later printing. Should users be able to override this (usually correct)

keyboard-interactive
Is there a way for a PAM module to force a client (and the server) to use kbd-interactive? As far as I can tell, when in the INITIAL_LOGIN phase, all communication with the client returns a PAM_CONV_ERR. I am trying to write a PAM module that will prompt a user for a second username and a second password in order for the module to succeed so that proper authentication relies on the ability

pam_open_session w/o tty on Solaris
Hello, all- Apparently, under Solaris (I can personally confirm SunOS 5.7 and 5.8), pam_open_session will generate a segfault if PAM_TTY is not set. The obvious symptom of this is that OpenSSH 2.9.9p2 will segfault on any operation that does not request a tty (do_exec_no_pty). Based on a quick google search, this seems to have been encountered by others, though the specific symptoms seem to
