FYI The fix for this is being prepared here: opensearch-project/security#2987

The upgrade of the SAML libs required additional permissions and the error was not caught in integ tests for the security plugin, but instead caught in this repo

I think we can close this for now since the main branch of security frontend has been unblocked.
