Amir Alexander Abdelbaki 5d56984e38 feat(ansipa): store LUKS backup keys on SMB share with KeyAdmin access control
ansipa-smb-setup.sh:
- Adds KeyAdmin Linux group and luks-upload service account (member of
  KeyAdmin) on the IPA container, both persisted across restarts.
- LUKS base dir /data/luks-keys owned root:KeyAdmin, mode 2750 (setgid
  so new files inherit the group).
- New [ansipa-luks-keys] SMB share: valid users = @KeyAdmin, read only,
  write list = luks-upload. Human admins gain read access by being added
  to KeyAdmin: useradd -r -G KeyAdmin <user> && smbpasswd -a <user>.
- LUKS_KEY_UPLOAD_PASSWORD sourced from env / /data/samba/ansipa-smb.env
  alongside the existing SMB_SCAN_PASSWORD.

collect-luks-keys.yml:
- After fetching /_LUKS_BACKUP_KEY from each client, uploads it to the
  ansipa-luks-keys share via smbclient using a temp credentials file
  (no_log, deleted in post_tasks).
- Local staging copy is removed after a successful upload.
- SMB credentials file uses an epoch-stamped path to avoid collisions.

.env.example: documents LUKS_KEY_UPLOAD_PASSWORD.

Amir Alexander Abdelbaki aced2c754e feat(ansipa): add daemon enable/disable policy via host-group regex
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.

Amir Alexander Abdelbaki c56c86d57b fix(freeipa): harden container SMB setup and fetch-alerts script
ansipa-smb.service: WantedBy=multi-user.target (was smb.service) so the
  setup service always runs at boot, not only when smb.service pulls it in

docker-compose.yml: add NetBIOS UDP ports 137/138 to match Dockerfile EXPOSE
  and nmb.service being enabled

ansipa-smb-setup.sh:
  - use printf '%q' when writing SMB_SCAN_PASSWORD to ansipa-smb.env so
    passwords with spaces or shell-special chars are correctly quoted
  - always write /etc/cron.d/ansipa-check-scans (remove the [[ ! -f ]] guard)
    since /etc/cron.d is on the ephemeral container layer and is lost on
    container recreation; the service runs on every start anyway

Dockerfile: add -e SMB_SCAN_PASSWORD and -p 445:445 to the quick-test comment

ansipa-fetch-alerts.sh: replace $NEW && log with [[ "$NEW" == true ]] && log
  to avoid set -e ambiguity with the 'false' builtin

Amir Alexander Abdelbaki 11e66dbddd feat(freeipa): scan result reporting, alert notifications, and SMB share
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

Amir Alexander Abdelbaki fb8ca498ef feat(freeipa): add AppArmor deny profiles to binary blocking policy
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.

Amir Alexander Abdelbaki 45fd7e5d36 feat(freeipa): add policy enforcement for binary blocking, backups, scans, and sudo
Introduces a FreeIPA host-group-driven policy system alongside a sudo
rules management playbook:

- ansipa-enforce-policies.sh: client-side enforcer (systemd timer, 30 min)
  - policy-block-binary-<name>: PATH-priority wrapper blocks the binary
  - policy-timeshift-backup: daily Timeshift snapshot cron (03:00)
  - policy-security-scan: daily ClamAV/rkhunter/chkrootkit cron (02:00)
  Policies are reversible — leaving a group removes enforcement on next run.

- deploy-ansipa-policies.yml: deploys enforcer + systemd service/timer to clients

- manage-sudo-rules.yml: creates FreeIPA sudo rules (allow_sudoers,
  allow_sudo_nopasswd) that SSSD clients already pick up via --sudo enrollment.

Amir Alexander Abdelbaki f1ea6dcb54 ansible: add collect-luks-keys playbook for LUKS backup key archival
New playbook collect-luks-keys.yml connects to all enrolled FreeIPA
clients, checks for /_LUKS_BACKUP_KEY (placed there by the installer
when encryption is enabled), and fetches each key to the Ansible
controller as luks-keys/<HOSTNAME>_LUKS_BACKUP_KEY (mode 0400).

Hosts without the file are reported but not treated as errors.
The luks-keys/ store directory is created with mode 0700.

Usage:
  ansible-playbook -i inventory collect-luks-keys.yml

Can be scheduled via cron on the controller for automatic collection.

Amir Alexander Abdelbaki fb9893504c setup: add FreeIPA Flatpak group installer (fp_install_* groups)
IPA group naming: fp_install_org__mozilla__firefox (dots encoded as __)
Decoding: sed strips prefix, then s/__/./g restores the Flatpak app ID.
Single underscores in app IDs are preserved unambiguously.

ansipa-install-flatpaks.sh:
- kinit with host keytab, queries ipa group-find --pkey-only with awk $NF
- Validates decoded ID against reverse-domain regex before installing
- Ensures flathub system remote exists
- System-scope install (flatpak install --system) since service runs as root
- Timer offset to 4 min (after packages at 2 min) to avoid contention

deploy-ansipa-install.yml updated to deploy the Flatpak script, service,
and timer alongside the existing package installer.

Amir Alexander Abdelbaki c51af40fce setup: add freeipa-client module and FreeIPA group-based module automation
- Add freeipa-client module (sssd, cyrus-sasl-gssapi, freeipa-client AUR)
  with post-install enrollment hints; wired into tui-install.sh and
  install-modules.sh
- Add ansipa-install-modules.sh: reads IPA host groups named
  ansipa-module-<name>, applies matching module scripts via a yay wrapper
  that drops to ANSIPA_USER so AUR builds work from the root service
- Add ansipa-install-modules.service + .timer (boot + 30 min)
- Add deploy-ansipa-modules.yml Ansible playbook that deploys scripts,
  writes /etc/ansipa-modules.conf, and enables the timer

Amir Alexander Abdelbaki f66775ce54 setup: add FreeIPA image builder and Keycloak integration
freeipa-image-builder.sh: TUI chooser that builds a FreeIPA server image
and exports it to four target formats:
  docker      — builds via podman/docker, optional registry push
  lxc         — exports container rootfs as .tar.zst Proxmox CT template,
                 generates pct import instructions
  proxmox-vm  — downloads Rocky/Fedora cloud image, customizes with
                 virt-customize, outputs QCOW2 + cloud-init user-data.yml
  oci-archive — skopeo OCI tarball for air-gapped import

Keycloak TUI option generates the full constellation:
  docker-compose.yml   FreeIPA + Keycloak + PostgreSQL stack
  .env                 pre-filled env template (passwords placeholder)
  keycloak-configure.sh  post-start Keycloak REST API config script

image/Dockerfile: Fedora 41 + freeipa-server-dns + ansible-core,
systemd-enabled container (CMD /sbin/init).

image/ipa-first-boot.{sh,service}: systemd oneshot that runs
ipa-server-install on first container/VM boot from env vars
(IPA_DOMAIN, IPA_ADMIN_PASSWORD, IPA_DM_PASSWORD, and optionals).
ConditionPathExists=!/etc/ipa/default.conf makes it idempotent.

image/keycloak-configure.sh: Keycloak REST API automation that:
  - waits for Keycloak readiness
  - creates a realm
  - wires FreeIPA LDAP user federation (READ_ONLY, vendor=rhds)
  - adds attribute mappers: email, firstName, lastName, uidNumber
  - adds group mapper (IPA groups → Keycloak groups, cn=groups,cn=accounts)
  - triggers an initial full user sync

image/docker-compose.yml: freeipa + postgres + keycloak services on
a private 172.30.0.0/24 bridge; FreeIPA has a fixed IP so Keycloak
can resolve it via extra_hosts.

Amir Alexander Abdelbaki 7279a781b0 setup: add FreeIPA server module and generic client script
freeipa-server.sh: interactive installer that collects domain, realm,
IP, admin/DM passwords, DNS, KRA, NTP, and AWX/Ansible settings;
runs conflict pre-flight (checks for existing named/dirsrv/krb5kdc,
ports 389/636/88, and /etc/ipa/default.conf); configures firewalld/ufw;
runs ipa-server-install; and outputs a ready-to-distribute client
package to ~/freeipa-output/ containing:
  - freeipa-enroll.sh (server defaults baked in)
  - freeipa-client.sh (server defaults baked in)
  - freeipa-client-answerfile.json (pre-filled, password intentionally blank)
  - auto-enroll-ansible.sh (AWX defaults embedded, still overridable)
  - README.txt

freeipa-client.sh: thin wrapper around freeipa-enroll.sh with three modes:
  --answerfile FILE   read JSON with jq, build args, exec freeipa-enroll.sh
  --interactive       prompt for every field, then exec freeipa-enroll.sh
  [flags]             passthrough directly to freeipa-enroll.sh

freeipa-client-answerfile.json: template with current server defaults
(freeipa.abdelbaki.eu); freeipa-server.sh sed-replaces these when
generating customized copies.

Supported server OS: RHEL/Rocky/AlmaLinux/Fedora (primary), Arch (warned).
