OXICLOUD_MAGIC_LINK_OPEN_TO_PASSWORD_USERS (default false)
For security I recommand to keep it false
OIDC cannot be bypassed because OIDC may have MFA in place
Backend
- RegisterDto — username and password both become Option<String> with #[serde(default)] so JSON can omit them entirely.
- AuthApplicationService::register — username uniqueness check skipped when None (multiple NULLs OK under the UNIQUE index); password hashing skipped when None; User::new called with the actual Options instead of forcing Some(...).
- auth_handler::register — branches on dto.password.is_none(). With password → existing 201 + UserDto. Without → triggers MagicLinkInviteService::send_login_link(&email) best-effort, then returns 200 + {"message": "Check your email…"}. The
OIDC-mode-disables-password-registration gate now only fires for the password path (email-only signup is still allowed even in OIDC-only mode, because it doesn't store a password).
- magic_link_handler::redirect_target — new 3-way decision tree:
- Resource target (folder invitation) → /#/files/folder/{id} (existing)
- NULL resource + is_external = false → /#/files (the welcome path for new internal users — they have a home folder)
- NULL resource + is_external = true → /#/sharedwithme (the existing external-user landing)
Tests
- New tests/api/registration.hurl with 9 requests covering: classic (with-password) register → 201 + UserDto, email-only register → 200 + uniform message + welcome magic-link captured, redemption → 302 to /#/files + cookies set, profile read → username
absent + is_external: false, resend magic-link works (eligible while passwordless), cleanup deletes both new users.
- Wired into tests/api/run.sh right after auth_login.hurl.
Plan additions
- auth-simplification.md gained PR 22 at the bottom of the PR sequence — device-bound magic-link redemption via challenge cookie + asymmetric TTLs (login: 10 min, invitation: 24 h). Full design recap, schema migration, config knobs
(OXICLOUD_MAGIC_LINK_LOGIN_TTL_MINUTES / _INVITE_TTL_HOURS), and Hurl coverage outline are in the plan. Slots in before PR 21's docs so the architecture page describes the final state from the start.
Checks — cargo fmt, cargo clippy --all-features --all-targets -- -D warnings, cargo test --lib (297 passed), biome, stylelint, tsc, full Hurl suite (16 files) all green.
username: now optional, if defined 2..64 chars
password: now optional (no mode __NO_PASSWORD...__)
oidc: now optional
important: if need Nextcloud, username must be defined
- add possibility to grant an external user.
- route /api/users/{id} added (rate limited for security)
- security: start route limitation for external users
ex: they must not browse /api/users/{id} nor addressbook
- SMTP has a mock to enable end to end test and validate the whole path
(via OXICLOUD_SMTP_MOCK)
- add email normalisation ( including punicode)
- api to share to external user
reflect OIDC
schema migration, User entity additions, and three defense-in-depth gaps closed, with all 280 unit tests and 13 Hurl files green
infrastructure (lettre + EmailSender port).
- Migration migrations/20260612000003_users_username_email_login.sql — adds nullable given_name/family_name columns to auth.users.
- User entity (src/domain/entities/user.rs) — has_login_credential() placeholder-check encapsulation, set_username revalidating setter, given/family-name fields + getters/setters, validate_username widened 32→254 and now accepts email shape.
from_data_full extended with two new params; all 7 callsites in user_pg_repository.rs updated.
- Schema-side legacy guards (src/application/services/auth_application_service.rs) — bumped the duplicated 32-char check in setup_create_admin and admin_create_user to 254 to match.
- Gap #1 (subject_group_service.rs) — add_member now rejects external candidates with an audit-logged AccessDenied. Service gained an Arc<UserPgRepository> field, wired through DI. New integration test test_external_user_cannot_be_added_as_member.
- Gap #2 (user_repository.rs + auth_ports.rs + user_pg_repository.rs) — list_users/search_users gained an include_external: bool param defaulting effectively to false everywhere internal-user-facing. auth_application_service exposes a new
list_users_including_external for the admin surface.
- Gap #3 (pg_acl_engine.rs) — expand_user now SELECTs is_external and skips INTERNAL_GROUP_ID for externals; defaults to is_external=true on missing user to fail closed.
prepare identity service for external users, support of:
- magic_link (url challenge via email)
- self issued oidc (eventually social login)
- open cloud mesh
- AuthzCacheLifecycleHook — invalidates the user_groups_cache Moka entry on logout/delete.
- SessionRevocationLifecycleHook — explicit per-session firing of on_user_logout (currently per-call); session revocation inside the user-delete transaction.
- DeletionMode-driven policy in HomeFolderLifecycleHook::on_user_deleted (trash vs hard-delete based on AdminDelete / GdprPurge).
- Refactor delete_user_admin to expose a transaction handle so on_user_deleted can abort atomically.
