Found while running the policy matrix and NAT/WAN scenario in VMs:
- ansipa-enforce-policies.sh and the dev_security-scan generated script called
`hostname -f`, but the hostname binary (inetutils) is not installed on a
minimal Arch system, so the enforcer aborted with "hostname: command not
found" on every run. Add an ansipa_fqdn() helper (hostnamectl / getent /
/etc/hostname / kernel-hostname fallback chain) and use it; inline the same
fallback in the standalone scan script.
- Fix two stacked bugs that meant CheckMK push mode — the only monitoring
transport that works when a client is behind NAT — never functioned:
* ansipa-checkmk-setup.sh referenced IPA_ADMIN_PASS in the DONE_FLAG
early-exit path, but that variable was assigned only afterwards, so every
rerun kinit'd with an empty password, failed silently, and skipped the
push-mode request writer. Resolve config before the early exit.
* _write_push_requests parsed `ipa hostgroup-show dev_mon_base` members with
awk that did `next` on the "Member hosts:" line — but ipa prints members on
that same line, so the only line with hostnames was discarded and no push
request was ever written. Rewrite the awk to capture the label line's value
plus wrapped continuation lines. Verified end-to-end: requests are written
and CheckMK flips the host to cmk_agent_connection=push-agent.

The 1550-line ansipa-enforce-policies.sh is replaced by a slim orchestrator
that sources policy files from policies.d/ — one file per policy type — via
a shared lib/ansipa-policy.sh that consolidates all IPA group discovery into
two queries (one host-show, one group-find) instead of five or more.
New files:
- ansible/lib/ansipa-policy.sh shared constants, log/warn, _ansipa_discover(),
_smb_parse_cred(), _ansipa_sync_policystore()
- ansible/policies.d/dev_daemon.sh
- ansible/policies.d/dev_timeshift-backup.sh
- ansible/policies.d/dev_security-scan.sh
- ansible/policies.d/dev_no-local-users.sh
- ansible/policies.d/dev_local-sudo.sh
- ansible/policies.d/dev_ssh.sh
- ansible/policies.d/dev_mon.sh includes usr_mon_logins (same CMK dep)
- ansible/policies.d/usr_admin.sh
- ansible/policies.d/usr_block-binary.sh
- ansible/policies.d/usr_prt.sh
- ansible/policies.d/usr_scan-notify.sh
- ansible/policies.d/usr_smb.sh
- ansible/policies.d/usr_policystore.sh NEW: auto-mount ~/policystore for
usr_smb_adm_policystore members
The policies.d/ folder on the FreeIPA container is exposed as an SMB share
(ansipa-policystore) so admins can live-edit policy files without Ansible.
The enforcer syncs from the share before each run; cached local files are
used as fallback when SMB is unreachable.
- ansipa-smb-setup.sh: adds ansipa-policystore share + smb-policystore system
user + usr_smb_adm_policystore IPA group with auto-generated credential
- deploy-ansipa-policies.yml: deploys lib/ and policies.d/ to enrolled clients;
adds optional seed_policystore task for bootstrap
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- ansipa-enforce-policies.sh header: add missing dev_ssh_*, usr_smb_r_*,
usr_smb_rw_*, dev_mon_* (base/malware/timeshift/power), usr_mon_logins
with concise descriptions matching actual behaviour. Notes section
updated with CheckMK setup prerequisite.
- ansipa_packages local check: replace broken rpm||dpkg fallback (wc -l
always exits 0 so dpkg/pacman branches were never reached) with an
if/elif/elif that probes for rpm, dpkg, or pacman in order. Includes
pacman.log-based recent-packages list for Arch hosts.
- deploy-ansipa-policies.yml prerequisites: add CheckMK and SMB mount notes.
- .env.example: add CheckMK section (CMK_ADMIN_PASSWORD, CMK_SITE_ID).

Adds full CheckMK CE 2.3 monitoring integration to the ansipa policy
enforcement system. Monitoring is group-driven — adding a host to an
IPA hostgroup installs the relevant agent checks automatically.
New monitoring groups:
dev_mon_base — install check-mk-agent, register host in CMK;
packages check + built-in CPU/RAM/disk/uptime
dev_mon_malware — ClamAV scan results from dev_security-scan log
dev_mon_timeshift — Timeshift snapshot age (WARN >5d, CRIT >10d)
dev_mon_power — CPU package TDP via Intel RAPL or lm-sensors
usr_mon_logins — SSH login attempts (success/failed/invalid-user)
Key implementation details:
- ansipa-checkmk-setup.sh: one-time folder/group creation on FreeIPA
container; reads automation secret from shared cmk-creds volume;
stores credentials in IPA dev_mon_base description for clients
- ansipa-checkmk.service: starts after IPA first-boot, retries until
both IPA and CheckMK are ready
- docker-compose.yml: CheckMK container adds port 8000 (agent receiver
for push mode); command override writes automation.secret to shared
volume, patches cookie_auth.conf for API access, and polls
/cmk-creds/push-mode-*.req to configure push-agent hosts in hosts.mk
- ansipa-enforce-policies.sh: local check scripts for all 5 groups;
cmk-agent-ctl registration + auto push timer when push mode is active
- CheckMK REST API path corrected to /cmk/check_mk/api/1.0/ (not
/cmk/api/1.0/ which returns 404 in 2.3)
- .gitignore added to prevent accidental commit of .env test creds

usr_smb_r_<name> / usr_smb_rw_<name> (user groups):
- Server creates /data/smb-shares/<name>/ with smb-<name> system user,
setgid directory, and Samba share stanzas [usr-<name>-r/rw] on startup
- Auto-generates credentials and stores them in IPA group descriptions
(cifs://<host>:<samba-user>:<password>) so no out-of-band secret distribution
- Client mounts //ipa/<share> at ~/‹name› for logged-in members;
rw membership wins over r when user is in both groups
- Revert: unmounts and rmdir the mount point on group leave
dev_ssh_<userid> (host group):
- Reads IPA user's SSH public keys (ipasshpubkey / --all output)
- Writes them into /home/<userid>/.ssh/authorized_keys in an
ansipa-managed section (preserves manually-added keys)
- Home dir is created if it doesn't exist (user may not have logged in yet)
- Revert: removes only the ansipa-managed section on group leave
- Enables same-key SSH access from any registered device to enrolled hosts
Also: add cifs-utils + openssh-server to Ansible package list

Fixes found during a complete archiso → FreeIPA DC → client enrollment →
ansipa policy deployment test cycle (Rocky 9 client VM, FreeIPA in Docker):
arch-autoinstall.sh:
- Add openssh to pacstrap — was missing, breaking headless/automated installs
- Enable sshd at boot and set PermitRootLogin yes for post-install access
ansipa-install-packages.sh:
- Fix broken uninstall logic: three always-true conditions caused every package
removal to be silently skipped; replace with a state-file-based approach that
tracks packages installed by ansipa and removes only those when the IPA group
disappears
ansipa-enforce-policies.sh:
- Add usr_admin policy: creates /etc/sudoers.d/ansipa-usr-admin granting full
sudo to the FreeIPA usr_admin user group on every enrolled host; reverted
when the IPA group is deleted
- Add usr_prt_<printer> policy: auto-adds CUPS printers for FreeIPA user group
members at login; printer URI stored in IPA group description; per-user ACL;
reverted when group is deleted or membership ends
deploy-ansipa-policies.yml:
- Document usr_admin and usr_prt_* policies in header comment
- Install cups package on clients (required for printer policy)
FreeIPA container (image/):
- Add docker-env.service: extracts IPA_*/SMB_*/LUKS_*/KEYCLOAK_* env vars from
/proc/1/environ into /etc/container.env on container start; services read from
there rather than relying on PassEnvironment (which is lost on container restart)
- Add run.sh: wrapper that starts FreeIPA with --cgroupns host, required on cgroup
v2 hosts (WSL2, recent Linux) because Docker Compose schema does not expose
cgroupns_mode; also wires LUKS_KEY_UPLOAD_PASSWORD which the SMB service needs
- Dockerfile: copy + enable docker-env.service; add glibc-langpack-en for locale
- ansipa-smb.service: use EnvironmentFile=/etc/container.env (via docker-env.service)
instead of PassEnvironment; add docker-env.service dependency
- ipa-first-boot.service: add docker-env.service dependency + EnvironmentFile
- ipa-first-boot.sh: add --skip-mem-check (container has limited cgroup memory
visibility); remove --no-reverse from non-DNS path (was invalid without DNS)
- docker-compose.yml: add prominent cgroupns note explaining when to use run.sh

policy-scan-notify is now a FreeIPA *user* group instead of a host group,
so alert notifications follow the user to every enrolled machine. The
fetch-alerts timer is installed fleet-wide on any host where the group exists;
the profile.d snippet gates notification daemon start on runtime group
membership (id(1) / SSSD) so non-members log in unaffected.

policy-block-binary-<name> is now a FreeIPA *user* group instead of a host group,
so restrictions follow the user to every enrolled machine. The PATH wrapper is
installed on all hosts and checks group membership at runtime via id(1)/SSSD,
passing non-members through transparently. __ in the group name decodes to .
so Flatpak app IDs are supported (flatpak run fallback included). AppArmor layer
removed since per-user confinement requires a different approach and the wrapper
alone is sufficient. Adds local_sudo_<username> host group policy which writes
a sudoers drop-in granting that user full sudo on the specific device, reverted
on group leave.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Adds a new host group policy `no_local_users` that locks the passwords of root
and all local users (UID >= 1000) via `passwd -l`, ensuring only FreeIPA domain
accounts with centrally-managed sudo rules can authenticate and gain elevated
privileges. Leaving the group reverts by unlocking every account tracked in the
state file. Updates docs with group reference entry and Local User Lockdown section.

Host groups named policy-daemon-enable-<unit> and
policy-daemon-disable-<unit> are now matched by a wildcard case arm in
the group parser — no per-service configuration required.
Enforcement (every 30 min via existing timer):
enable: systemctl enable --now <unit>; state written to
/var/lib/ansipa-policies/daemon-enabled
disable: systemctl disable --now <unit>; state written to
/var/lib/ansipa-policies/daemon-disabled
revert: when a host leaves a group the opposite action is applied
on the next run (enable→disable, disable→enable)
conflict: unit in both lists is skipped with a warning
The .service suffix is optional — _svc_unit() appends it when the name
contains no dot, so all systemd unit types work as-is.

Container (ansipa image):
- Add samba + cronie to Dockerfile; expose ports 445/139
- ansipa-smb-setup.sh: idempotent setup of smbd + scanupload user +
/data/scan-results/{archive,alerts}/ on every container start
- ansipa-smb.service: runs setup before smb.service on each boot
- ansipa-check-scans.sh: hourly cron on server; analyses archive logs for
ClamAV/rkhunter/chkrootkit findings and writes <host>/<date>.alert files
- docker-compose.yml: add SMB_SCAN_PASSWORD env var + port mappings
- .env.example: document SMB_SCAN_PASSWORD
Client (policy-security-scan):
- Scan script now uploads log to //ipa-server/ansipa-scans/archive/<host>/
via smbclient after each run
Client (policy-scan-notify — new policy group):
- ansipa-fetch-alerts.sh: root timer (10 min) downloads alerts from SMB into
~/administration/<hostname>/ for each active login session; deletes server
alert when user removes local file (acknowledgment)
- ansipa-scan-notify.sh: user daemon started via /etc/profile.d/ansipa-notify.sh;
sends notify-send every 10 min while *.alert files remain in ~/administration/
- deploy-ansipa-policies.yml: installs samba-client, deploys SMB creds file
(/etc/ansipa-smb.creds, 0600), and deploys both notification scripts

Binary blocking now applies two layers:
1. PATH-priority wrapper in /usr/local/bin/ (existing)
2. Empty AppArmor profile in /etc/apparmor.d/ loaded in enforce mode
An empty AppArmor profile denies all access — the blocked binary cannot
load shared libraries and exits immediately with a permission error,
covering callers that use absolute paths and bypassed the wrapper.
AppArmor layer is skipped silently when apparmor_parser is not present,
and deferred with a warning if the real binary is not yet installed.
Profiles are unloaded and deleted when the host leaves the policy group.
