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.
