Right. You are setting PAM configuration. But chroot doesn't use PAM and so it has no effect. Using 'chroot' then PAM is not involved at all and therefore PAM configuration has no effect. Since you did not provide a command it invoked your $SHELL inside the chroot. But inside the chroot you can invoke a command that uses pam. If you launch 'su' then su will use PAM and set up your PAM configuration. $ sudo chroot /opt/id/epsilon su That invokes su inside the chroot. Since su uses PAM then the PAM configuration should have effect. But I didn't test it. :-) Try that. Bob
