Scenario

An IdP schema update lands and OpenSearch users authenticate successfully but fall back to minimal permissions.

What to check first
  • Identify the primary failure signal in the The Roles Were in the Token, Just Not Where the Plugin Still Looked scenario.
  • Separate visible symptoms from the underlying technical dependency.
  • Describe the safest recovery path and the follow-up prevention work.
Checking checklist
  1. Summarize the current impact and the last known change.
  2. Collect direct evidence from logs, runtime state, and configuration before changing anything.
  3. Separate immediate recovery from permanent prevention work.
Recovery and prevention

Inspect the live token claim structure before widening backend roles or local permissions.

What usually causes An OpenSearch role mapping looks correct and SSO users still lose access in production?

Teams often blame expired caches when the plugin simply points at the wrong claim structure.

What should you document after resolving An OpenSearch role mapping looks correct and SSO users still lose access?

SSO upgrades should validate both claim names and claim nesting shape against downstream role mappers.
