Authentication

DeltaFi uses role-based access control (RBAC) to secure API endpoints. Every endpoint requires a specific permission, and users are granted permissions through roles.

For setup and configuration instructions, see Authentication Configuration and Authorization Configuration.

Auth Modes

DeltaFi supports three authentication modes, configured via the auth.mode system property:

Mode	Value	Description
Basic	basic	Username/password authentication (default)
Certificate	cert	X.509 client certificate authentication via Distinguished Names
Disabled	disabled	No authentication; all requests treated as admin. For development only.

Basic Authentication

The default mode. Users authenticate with username and password via HTTP Basic auth. The default admin user's password is set with deltafi set-admin-password.

curl -u admin:password http://deltafi-host/api/v2/status

Certificate Authentication

Uses X.509 client certificates. The Distinguished Name (DN) from the certificate must match a DN configured for a user in the system. Requires a CA certificate chain stored in a Kubernetes secret.

Disabled Mode

All requests are treated as coming from the admin user with full permissions. Intended for local development and testing only.

Request Headers

After initial authentication, the auth gateway populates these headers on forwarded requests:

Header	Description
X-DeltaFi-User-Name	Authenticated username (or DN in cert mode)
X-DeltaFi-User-Id	User's UUID
X-DeltaFi-Permissions	Comma-separated list of granted permissions

Permission Model

Permissions follow an RBAC hierarchy:

User → Roles → Permissions

• A user is assigned one or more roles
• Each role contains one or more permissions
• Endpoint access requires a specific permission (or the Admin permission)

Admin Override

The Admin permission grants access to every endpoint. All permission checks include an implicit OR Admin clause:

@PreAuthorize("hasAnyAuthority('PermissionName', 'Admin')")

Default Roles

Role	Permissions	Purpose
Admin	Admin	Full system access
Ingress Only	DeltaFileIngress	Data ingestion service accounts
Read Only	Read-only permissions	View-only access

Combined Permissions

Some endpoints require multiple permissions simultaneously:

• DeltaFileReplayAndAcknowledge — requires both DeltaFileReplay and DeltaFileAcknowledge
• SnapshotCreateAndRevert — requires both SnapshotCreate and SnapshotRevert
