Original GitHub issue: https://github.com/netbirdio/netbird/issues/4541

Describe the problem

Clarification request: NetBird Keycloak guide creates a realm-level client scope api with an Audience mapper and links it to netbird-client.
Do I actually need the realm-level api scope, or is it enough that the JWT’s aud equals/contains NETBIRD_AUTH_AUDIENCE regardless of whether Keycloak injects it via a realm-level scope or a client-level (dedicated) mapper?

Expected behavior
NetBird accepts tokens when aud equals/contains NETBIRD_AUTH_AUDIENCE, regardless of whether the audience was added by a realm-level client scope or a client-level (dedicated) mapper.

Are you using NetBird Cloud?
No

NetBird version
v0.58.0 (self-hosted)

Is any other VPN software installed?
No.

Debug output
N/A — this is an Netbird-related oidc configuration/behavior question, no runtime error to attach.

Screenshots
N/A

Additional context
Keycloak context: You can attach an Audience protocol mapper either directly to the client (its “dedicated” client scope — mappers attached to that client) or to a realm-level client scope that you link to the client (Official docs follow this approach)

Keycloak: v26.3.4
Docs reference: https://docs.netbird.io/selfhosted/identity-providers#keycloak

@rismalrv commented on GitHub (Sep 29, 2025):

NetBird is agnostic to how Keycloak injects this audience (e.g., via a realm-level client scope with an Audience mapper, or a dedicated client-level Audience mapper). Closing the issue as the functionality is supported.
