# Another method: Leave PAM on, but it needs a few more fixes.

# 1. PAM LoginUID fix. Otherwise user is kicked off after login.
|

|
# Or you might start container with --cap-add AUDIT_CONTROL
|

|

# RUN sed 's@session\s*required\s*pam_loginuid.so@session optional pam_loginuid.so@g' -i /etc/pam.d/sshd

# 2. systemd-logind hang 25s fix
