Summary

solar-ui supports operation without OIDC:
If no --oidc-issuer argument is configured, the server selects auth.NewNoopProvider().
The Helm chart nevertheless requires OIDC values whenever ui.enabled=true and always renders OIDC arguments 🤷🏻‍♂️

This prevents users from selecting the existing no-OIDC mode through Helm.

The chart template currently renders mandatory values:

- --oidc-issuer={{ required "ui.oidc.issuer is required when ui.enabled=true" .Values.ui.oidc.issuer }}
- --oidc-client-id={{ .Values.ui.oidc.clientID }}
- --oidc-redirect-url={{ required "ui.oidc.redirectURL is required when ui.enabled=true" .Values.ui.oidc.redirectURL }}

Reproduction

Just Enable the UI without configuring an OIDC issuer:

ui:
  enabled: true
  oidc:
    issuer: ""
    redirectURL: ""

Render the chart:

helm template solar ./charts/solar --set ui.enabled=true

Actual behavior

Helm rendering fails because ui.oidc.issuer and ui.oidc.redirectURL are
required.

Supplying placeholder values makes the chart render, but the UI then attempts OIDC discovery and exits when the placeholder issuer is unreachable.

Expected behavior

When ui.enabled=true and ui.oidc.issuer is empty, the Deployment should omit all --oidc-* arguments and allow the binary to use NoopProvider 🤔 ?

Suggested fix

• Render OIDC arguments only when ui.oidc.issuer is non-empty.
• Require redirectURL only inside that OIDC-enabled branch.
• please add Helm rendering tests for UI with and without OIDC :)
