Hi Don-san. I am able to reproduce with the following procedure.
----------------- vagrant init ubuntu/xenial64 vagrant ssh # at xenial64 on VM echo 'session required pam_tty_audit.so enable=*' | sudo tee -a /etc/pam.d/common-session ----------------- When 'vagrant ssh' from other terminal, it is fail. I tested below environment. ----------------- vagrant@ubuntu-xenial:~$ uname -a Linux ubuntu-xenial 4.4.0-142-generic #168-Ubuntu SMP Wed Jan 16 21:00:45 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux vagrant@ubuntu-xenial:~$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 16.04.5 LTS Release: 16.04 Codename: xenial vagrant@ubuntu-xenial:~$ dpkg -l | grep -E 'libpam|linux-image' ii libpam-modules:amd64 1.1.8-3.2ubuntu2.1 amd64 Pluggable Authentication Modules for PAM ii libpam-modules-bin 1.1.8-3.2ubuntu2.1 amd64 Pluggable Authentication Modules for PAM - helper binaries ii libpam-runtime 1.1.8-3.2ubuntu2.1 all Runtime support for the PAM library ii libpam-systemd:amd64 229-4ubuntu21.15 amd64 system and service manager - PAM module ii libpam0g:amd64 1.1.8-3.2ubuntu2.1 amd64 Pluggable Authentication Modules library ii linux-image-4.4.0-142-generic 4.4.0-142.168 amd64 Linux kernel image for version 4.4.0 on 64 bit x86 SMP ii linux-image-virtual 4.4.0.142.148 amd64 This package will always depend on the latest minimal generic kernel image. vagrant@ubuntu-xenial:~$ ----------------- If you cannot reproduce this issue above procedure, you try to enable/disable other pam module. This problem is caused by an uninitialized stack variable, so it is important to manipulate the state of the stack to reproduce it. For example, it is good to activate pam_ldap. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1666203 Title: pam_tty_audit failed in pam_open_session To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pam/+bug/1666203/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
