dbflux-builtin-auth-provider

When to Use

• The auth provider should be compiled into DBFlux.
• The provider should appear in Settings → Auth Profiles without configuring an RPC service.
• The provider resolves credentials or registers secret/parameter value providers.

Source of Truth

• crates/dbflux_core/src/auth/mod.rs
• crates/dbflux_core/src/auth/types.rs
• crates/dbflux_app/src/auth_provider_registry.rs
• crates/dbflux_app/src/app_state.rs
• crates/dbflux_aws/src/auth.rs for built-in examples
• crates/dbflux_ui/src/ui/windows/settings/auth_profiles_section.rs for generic form behavior

Critical Patterns

• Prefer implementing DynAuthProvider when the provider needs a form definition, login URL callback, dynamic options, value-provider registration, or import/write-back hooks.
• AuthFormDef reuses DriverFormDef; do not create provider-specific UI rendering.
• Return secrets through ResolvedCredentials.secret_fields, never regular fields or logs.
• AuthSession.data and ResolvedCredentials.provider_data are opaque runtime data, not persisted config.
• Capability flags must describe real behavior, especially login support and verification URL progress.

Checklist

1. Define a stable provider_id() and display name.
2. Return an auth form definition for Settings → Auth Profiles.
3. Implement validate_session().
4. Implement login() and call the URL callback when interactive login exposes a verification URL.
5. Implement resolve_credentials() with clear separation between plain fields and secret fields.
6. Override register_value_providers() only for real secret/parameter backends.
7. Override import/write-back hooks only when the provider owns external profiles.
8. Register the provider in AuthProviderRegistry in AppState behind the correct feature gate.
9. Add tests for form parsing, session states, credential resolution, and secret redaction expectations.

Boundaries

• Do not log tokens, passwords, session tokens, access keys, or secret fields.
• Do not add auth-provider-specific UI branches unless the existing generic form seam is insufficient and the user approves a new generic seam.
• Do not persist opaque session/provider data.
