...d 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", remove unnecessary casts "(pam_handle_t *)" * fix typo in NEW_AUTHTOK_MSG * extend pamconv() to support real interactive prompting and display, in addition to the kludge to feed the user's password into PAM during initial login * add function do_pam_chauthtok() to call pa...

Hi, The main (and probably the only) use case of this PAM module is to let sudo authenticate users via their ssh-agent, therefore without having to type any password and without being tempted to use the NOPASSWD sudo option for such convenience. The principle is originally implemented by an existing module [0][1] and many pages that explain how to use it for such purpose can be found online.

I'm working with the latest code (pre14) with some patches I've made to get a clean compile. Running the sshd I get a segfault inside of pam_open_session. Figured I'd get a look at the data structures. I can't find them. There's a #typedef struct pam_handle pam_handle_t; in security/pam_appl.h, but I can't find a reference for pam_handle. Am I on drugs? Also, has anyone tried turning off pam for testing. Oh, is that ugly. It works, and I get a connection, but there's problems in the pty mapping that I couldn't get fixed with an stty command. Ben
