Issue Report

How can I enforce password policies in CoreOS ?

I tried to use to enforce requirements like minimum number of uppercase letters, lowercase letters, other characters etc,. But, in journals, I got a message saying is not found.

Under [pam] section in sssd.conf documentation, I did not find the above mentioned requirements to configure.

Can someone please help me understand how to configure password policies on CoreOS ?

Container Linux Version

$ cat /etc/os-release
NAME="Container Linux by CoreOS"
PRETTY_NAME="Container Linux by CoreOS 2023.5.0 (Rhyolite)"


CoreOS is running as a VM in a VMware environment.

Container Linux does not include pam_cracklib. If you want to add PAM modules, the pam.conf format can take an absolute path for the module name (so e.g. write it to /opt or package it for torcx).

@dm0-, Thank you for the info. Could you please show me an example ? Where should I add pam.conf file and what is the format ? Could you please point me to some documentation ?
