## Affects

***

Teams configuring Lender route authorization.

## What changed

***

Lender configures authentication with `PLUGIN_AUTH_ENABLED` and `PLUGIN_AUTH_HOST`. `AUTH_REQUIRED` is not a Lender configuration variable and is no longer listed in the prerequisites or deployment checklist.

This is a documentation correction that aligns the guide with the implemented configuration surface. It does not announce a runtime release.

## Impact

***

**Classification: Review recommended.** Remove reliance on `AUTH_REQUIRED` from Lender deployment templates and runbooks.

## What you need to do

***

<Steps>
  <Step>Review Lender manifests and runbooks that set or validate `AUTH_REQUIRED`.</Step>
  <Step>Configure `PLUGIN_AUTH_ENABLED` and `PLUGIN_AUTH_HOST` for deployments that enable route authorization.</Step>
  <Step>Verify that your identity provider is reachable and calls send bearer tokens with the required subject and permissions.</Step>
</Steps>
