...sername and this time for challenge-response. Pam_radius use pam->conv function, retrieved with pam_get_item(PAM_COM), with challenge-request and type PAM_PROMPT_ECHO_ON, to present the challenge-request to user and to retrieve the challenge-response. OpenSSH sets the PAM_CONV function to sshpam_passwd_conv() (defined in pam_auth.c). But this function doesn't have implemented the PAM_PROMPT_ECHO_ON flavor, and returns the PAM_CONV_ERROR :-( It should be possible to implement the PAM_PROMPT_ECHO_ON conversation either with read()/write() or with fdopen()/fprintf()/fgets()/fclose() (as is done...

Note that service modules are responsible for localizing any strings sent to the conversation function. ---- But sshpam_passwd_conv() "Assumes that echo-off prompts are for the password" and pass password as a reply. It could lead that password is exposed to a wrong consumer. Correct solution is to set AUTHTOK before pam_autheticate is called in sshpam_auth_passwd() function. Something like this: pam_set_item(sshp...

...with: Subject: PATCH: Public key authentication defeats passwd age warning. that sounds like it is closely related from Sep. 2004, but applying the patch found there hasn't helped my situation. I tried forcing the use of various conversation functions, (sshpam_store_conv, sshpam_tty_conv, sshpam_passwd_conv) but can't get anything to print to the users terminal. I've seen other posts which suggest that using posix_threads may work, but only if all other modules are thread-safe, and that this is not the preferred workaround. I'm running out of things to try, hence this post.

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

Hi I have upgraded from samba 3.6.19 to samba 4.0.13 on Debian Wheezy 64-bit with Samba 4.0.13 from wheezy-backports. I use winbind to authenticate against a two-server AD domain on Server 2012 functional level and forced LDAPS. After upgrading from 3.6.19 to 4.0.13 everything still works for me as usual. That is samba shares authentication, all things relying on the keytab, SSO logins with SSH

Hi All. OpenSSH is getting ready for a release soon, so we are asking for all interested parties to test a snapshot. Changes include: * sshd will now re-exec itself for each new connection (the "-e" option is required when running sshd in debug mode). * PAM password authentication has been (re)added. * Interface improvements to sftp(1) * Many bug fixes and improvements, for
