...e about why, if the noulogin file were printed properly they would get the proper explanation. if i make the module `optional' then the message is printed correctly, but obviously access isn't denied anymore. this is still curious since pam_motd never works, and it prints /etc/motd with a PAM_TEXT_INFO message via the same conversation mechanism. here is the pam config ive tested with: #%PAM-1.0 auth requisite pam_noulogin.so auth required pam_listfile.so item=user sense=deny file=/etc/ssh/ssh_rsa_only onerr=succeed auth required pam_unix.so auth required pam_en...

Hello sorry, for bothering you with this problem, but I ca't find solutions. I write small PAM module, and I've got the problem with conversation function with OpenSSH 3.5p1. When the message style is PAM_PROMPT_ECHO_ON, or PAM_PROMPT_ECHO_OFF everything is allright. But when I use PAM_TEXT_INFO, or PAM_ERROR_MSG, ssh prints nothing on the client side. Does anyone know the reason of this, and how can I print messages to the user.

Hi, There seems to be no way for PAM to inform a user why her ssh login attempt is being denied. Niether PAM_TEXT_INFO or PAM_ERROR_MSG conversation messages are passed on to the user by sshd unless the login is successful. This is causing great frustration for us at several sites where users can't figure out why their logins aren't working. Would a patch be accepted to display such text even on login fa...

The same thing happens when using PAM_ERROR_MSG, but PAM_PROMPT_ECHO_OFF/ON work correctly. Attached is an example module that works properly with sudo, but shows both messages at the same time, at the end of the PAM stack executio...

If the info_response code is going to test that the # of responses is < 100, then the info_request code should check that < 100 prompts are sent. It would be rude to send 101 prompts and then fail when the responses come back. I actually think the test should be removed altogether, the limit seems quite arbitrary, but here is a patch to not send > 100 prompts. With this patch, the test

...lso want to display a message to those users that are denied login, so i modified pam_motd to work in "account" section, but i can't get the message to be printed. I can't make pam_motd to work in the "session" section either. There's a section: message.msg_style=PAM_TEXT_INFO; message.msg="blahblah.."; pam_get_item(pamh,PAM_CONV,&conversation); conversation->conv(1,&pmessage,&resp,conversation->appdata_ptr); etc. but apparently its ignored by PAM, any ideas? __________________________________________________ Do you Yahoo!?

In OpenSSH 3.6.1p2, pam_open_session() ran with a conversation function, do_pam_conversation(), that fed text to the client. In OpenSSH 3.7.1p2, this is no longer the case: session modules run with a conversation function that just returns PAM_CONV_ERR. This means that simple session modules whose job involves printing text on the user's terminal no longer work: pam_lastlog, pam_mail, and

Hi All. This patch calls pam_chauthtok() to change an expired password via PAM during keyboard-interactive authentication (SSHv2 only). It is tested on Redhat 8 and Solaris 8. In theory, it should have simply been a matter of calling pam_chauthtok with the PAM_CHANGE_EXPIRED_AUTHTOK flag, it'd only change the password is if it's expired, right? From the Solaris pam_chauthtok man page:
