Phase 2/3 of DEBT-039. Switches FTP, POP3, IMAP, SMTP, Redis, and
LDAP from the legacy `username=` + `password=` SD-block shape to the
universal credential shape (`principal=` + `secret_printable=` +
`secret_b64=`) the new Credential storage model expects.
Pattern is uniform across all six services:
_log("auth_attempt", username=u, principal=u, **encode_secret(pw))
Each service emits the canonical SD keys. The ingester's native-shape
branch (introduced in 2f47f67) now writes their cred attempts
directly without going through the legacy adapter. Once Phase 3
removes the adapter the contract becomes single-shape.
Per-service notes:
- POP3 / IMAP — `status="success"|"failed"` renamed to
`outcome="success"|"failure"` to match Credential.outcome's
vocabulary; the ingester reads outcome directly.
- SMTP — AUTH path migrated; in addition the existing mail_from
event now exposes a parsed `domain=` field alongside the original
`value=` so future "what domains do attackers spoof from" analytics
have an indexed field. Not stored in Credential — regular Log row.
- Redis — was silently dropped by the legacy adapter (no `username`
field). Native branch handles `principal=None` correctly. BONUS
FIX: the Redis 6+ ACL syntax `AUTH <user> <pw>` now captures the
ACL username as principal (was previously discarded).
- LDAP — was silently dropped by the legacy adapter (no `password`
recognition for the `bind` event). Now lands as
`principal=<dn>`. BONUS FIX.
Tests (tests/services/test_cred_emitters.py, 9 cases):
- per-service native-shape ingest path produces correct Credential
rows; outcome maps for POP3/IMAP; principal=None for legacy Redis
AUTH; principal=dn for LDAP.
- mail_from event does NOT trigger a credential write (it's a
Log-only observation, not auth).
- 0xff/NUL/ANSI bytes in passwords survive losslessly through
secret_b64 even when secret_printable is sanitized.
Phase 3 deletes the legacy adapter once all migrations land — the
adapter has no live emitters to handle anymore.
The docker build contexts and syslog_bridge.py lived at repo root, which
meant setuptools (include = ["decnet*"]) never shipped them. Agents
installed via `pip install $RELEASE_DIR` got site-packages/decnet/** but no
templates/, so every deploy blew up in deployer._sync_logging_helper with
FileNotFoundError on templates/syslog_bridge.py.
Move templates/ -> decnet/templates/ and declare it as setuptools
package-data. Path resolutions in services/*.py and engine/deployer.py drop
one .parent since templates now lives beside the code. Test fixtures,
bandit exclude path, and coverage omit glob updated to match.
