If you recycle the PID you will inherit those. You need to start with a fresh set of attributes by forking off a clean process from some well-defined parent process, before you restart PAM. pam_systemd for example will move the calling process into a cgroup of its own and that's really a one-way operation. Really, you cannot have the same process create multiple PAM sessions one after the other. The various PAM modules in use do not allow that, pam_systemd is just one of them.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
