similar to: PAM conversation stuff

As many of you know, OpenSSH 3.7.X, unlike previous versions, makes PAM authentication take place in a separate process or thread (launched from sshpam_init_ctx() in auth-pam.c). By default (if you don't define USE_POSIX_THREADS) the code "fork"s a separate process. Or if you define USE_POSIX_THREADS it will create a new thread (a second one, in addition to the primary thread). The

Hi. I'm one of the OpenSSH developers, and I've done some of the work on sshd's PAM interface recently. I've discovered some behaviour peculiar to LinuxPAM that I can't explain: changing the conversation function does not appear to work, even though the pam_set_item() call claims to succeed. The previous conversation function is still called. Background: the PAM API

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",

Hi there, I just tried out OpenSSH3.0p1 running on Solaris 8 with PAM (--with-PAM). The problem was mentioned some time ago and is still there :-( When a password is expired you are prompted to change it now, enter your login password and after doing so you are instantly disconnected. I think this is a problem with PAM and not SSH, but how can I get a solution on this ? sshd is running without

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

We recently started upgrading OpenSSH on our Sol8 systems and we've run into a problem were we can run commands on a remote system since we installed 3.7.1p1. The debug output from sshd is attached below. We use PAM in our environment, and have since 2.9.9p2. I think most of the systems were running 3.4p1 prior installing 3.7.1p1 and they were working - the only thing we replaced was

I tried replacing readpassphrase() for v2.9.9p2 on Sol8 with a different version that just calls getpassphrase(). It appears to solve the echo problem when the user tries to login in interactive mode and needs to change their password. Can anyone else try this with v2.9.9p2 on Solaris? Be sure to add: #define HAVE_GETPASSPHRASE ... to config.h when compiling (since it's not a configurable

Hi, freebsd-security. I have FreeBSD 5.3-STABLE. When I try to change user's password (via passwd) I recieve the following: passwd: entry inconsistent passwd: pam_chauthtok(): error in service module passwd: in pam_sm_chauthtok(): pw_copy() failed and password stays unchanged. There are no other errors in the authorization system at all. Contents of /etc/pam.d stayed unchanged (compared to

Hello there, We are using OpenSSH_3.9p1, OpenSSL 0.9.7d 17 Mar 2004 on various Solaris boxes with PAM and an LDAP server back end. Recently we have added a requirement for users to have complex passwords. The problem is, if a user's password has expired, when they log in they are prompted for a new password (good) but if they enter a non-complex new password the session is closed rather than

Hi All. Attached is a patch that converts pam_chauthtok_conv into a generic pam_tty_conv, which is used rather than null_conv for do_pam_session. This allows, for example, display of messages from PAM session modules. The accumulation of PAM messages into loginmsg won't help until there is a way to collect loginmsg from the monitor (see, eg, the patches for bug #463). This is because the

I ran into a weird problem yesterday where Putty can't connect to my OpenSSH/Sol box (and still can't ever since). On the Putty side I get the error message: "internal fault: chaos in SSH 2 transport layer" I've attached the "sshd -d -d -d" syslog output. Any ideas what's going wrong here? From a layman's point of view, it would appear that Putty and

Hello, I use cvs to download samba with pserver.samba.org i get the 2.0.4b version ! where can i get the last stable release (2.0.7) and alpha versions with cvs and anonymous ? Thanks Guy Roussin

I'm experimenting with smb + winbind. My host is joined to AD and I can login to my host fine using my AD credentials via SSH.?? The only issue is that I don't get a Kerberos ticket generated. In /etc/security/pam_winbind.conf I have: krb5_auth = yes krb5_ccache_type = KEYRING In /etc/krb5.conf, I also have: default_ccache_name = KEYRING:persistent:%{uid} Using wbinfo -K jas, then

I did re-read the whole thread again. Im running out of options.. When i look at : https://wiki.samba.org/index.php/PAM_Offline_Authentication You can do these last checks. Run the : Testing offline authentication as show on the wiki. Debian normaly does not have /etc/security/pam_winbind.conf, check if its there if so backup it remove it. Check if these packages are installed.

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:

A little problem, which is bugging me: when using PAM authentication, Dovecot (0.99.5) does not set the PAM_RHOST item, so the PAM modules cannot know who the client is. We need this for some PAM module doing access control. Changing passdb-pam.c to pam_set_item it seems trivial, but I'm bugged as to how to get the client name from there. It seems not to be available in the auth_request
