4.4.3.3.3 | PATCH | Ensure pam_pwhistory includes use_authtok | authselect_files" #401

Open dirkvdplas opened 1 month ago

Describe the Issue Problem with pamd module in roles/RHEL8-CIS/tasks/section_4/cis_4.4.3.3.x.yml Execution of the role breaks on task "4.4.3.3.3 | PATCH | Ensure pam_pwhistory includes use_authtok | authselect_files" when authselect is used. This seems to be related to an open bug in ansible pam.d module. See: https://github.com/ansible-collections/community.general/issues/5850

Expected Behavior we expect task "4.4.3.3.3 | PATCH | Ensure pam_pwhistory includes use_authtok | authselect_files" to execute successfully under all circumstances

Actual Behavior Error message: TASK [/home/user/basic-server/playbooks/roles/RHEL8-CIS : 4.4.3.3.3 | PATCH | Ensure pam_pwhistory includes use_authtok | authselect_files] *************************************************** changed: [ddu-inc-av001.dns.local] => (item=password) An exception occurred during task execution.

Control(s) Affected What controls are being affected by the issue

Environment (please complete the following information):

Additional Notes This seems to be related to an open bug in ansible pam.d module. See: https://github.com/ansible-collections/community.general/issues/5850

related authselect settings in roles/RHEL8-CIS/defaults/main.yml: `rhel8cis_allow_authselect_updates: true

rhel8cis_authselect_pkg_update: false rhel8cis_authselect_custom_profile_create: true rhel8cis_authselect_custom_profile_select: true rhel8cis_authselect: custom_profile_name: 'vdns_cis_hardened_profile' default_file_to_copy: "sssd --symlink-meta" options: with-sudo with-faillock without-nullok with-pwhistory`

Possible Solution As alternative for ansible pamd module maybe lineinfile can be used?

hi @dirkvdplas

Thank you for taking the time to raise this issue, there is a slightly newer approach taken for authselect in the new branch august_issues which i am currently working on. I am hoping this simplifies things and makes it more accessible for all the options that we are aware of. I hope to get this pushed up tomorrow for testing and merge to devel.

kindest regards
