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

Beyond any more general questions of whether pam sessions *should* be run as root, is there an immediate security concern with moving the pam_open_session (and pam_setcred) stuff to the parent (root) process?

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

I've attached two patches. The first just changes the output of "ssh -V" to print that it was built against rsaref if libRSAglue (which is built as part of openssl only when it is built against rsaref) is present at build-time. The second adds appropriate calls to pam_setcred() in sshd. Without them, our systems can't access AFS because the PAM modules only get tokens at a

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",

In do_pam_cleanup_proc(), there are 3 calls to PAM: 1) pam_close_session() - do lastlog stuff 2) pam_setcred(PAM_DELETE_CRED) - delete credentials 3) pam_end() - close PAM It appears that pam_setcred() always fails with the error PAM_PERM_DENIED. This is due to a check done pam_unix.so to not allow a caller with euid 0 to even try to delete their SECURE_RPC credentials. When sshd calls

while trying to sort out the PAM incompatabilities between openssh 3.0.2p1 and solaris 8 and sun's pam_krb5 i got some things to work. i'm really not sure where the appropriate place to submit patches is so for now i'm sending them here. this patch will allow PAM interoperability when using sun's pam_krb5 without using the system login routine (this way X forwarding will

We've been having trouble with OpenSSH 2.9p2, running on Solaris 8 (a domain of an E10k), with PAM authentication turned on. It intermittently crashes with signal 11 (seg fault) after the password is entered, after the MOTD is displayed, but before control is passed over to the login shell. I eventually managed to persuade sshd's child process to consistently crash, upon entry of an

The 2 errors: pam_setcred: error Permission denied Cannot delete credentials[7]: Permission denied Looks to be a major bug in the PAM module for Solaris-2.8/2.7/2.6. Has anyone from the list (developers of OpenSSH, endusers, hackers, etc.) came up w/ a solution? Even a temporary one? When authenticating yourself on the same system that worked, but when authenticating to another system failed. I

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

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

Hello, Here's the situation I'm facing : I'm running OpenSSH on a server. On a gateway, I forward TCP:22 to the server TCP:22. So far, so good. I can log in from inside the lan by connecting using standard SSH port, or from the other network through the gateway. Now, I'd like a different configuration for connections from the outside. I start another SSHd on the

I append a patch against openssh-3.5p1.tar.gz which adds a config option PAMServiceName. The option allows one to specify the PAM service at runtime in the config file rather than using __progname or having it hardwired to SSHD_PAM_SERVICE at compile time. I expect this to be useful if one wants to run multiple instances of sshd using different PAM configurations. With this patch
