[BUG] Default Route not applying with SAML

[kclinden]

I have OpenSearch Dashboards configured to go to /app/wazuh which works with Internal User logins, but when using SAML users are directed to /app/home

SAML Users not directed to default route

To Reproduce Steps to reproduce the behavior:

1. Configure Default Route
2. Configure SAML
3. Login to OS Dashboards

Expected behavior All users are redirected to the default route.

OpenSearch Version Version: 2.8.0, Build: rpm/db90a415ff2fd428b4f7b3f800a51dc229287cb4/2023-06-03T06:24:25.112415503Z, JVM: 17.0.7

This might relate to the behaviour of security-dashboards-plugin https://github.com/opensearch-project/security-dashboards-plugin/blob/main/server/auth/types/saml/saml_auth.ts#L64

That looks to be exactly the issue.

@opensearch-project/admin can we redirect this to security dashboards plugin repo?

[Triage] Hi @kclinden, thank you for filing this issue. It looks like this issue is similar to some previous work done supporting OIDC: https://github.com/opensearch-project/security-dashboards-plugin/pull/1899. I will go ahead and mark this as triaged and encourage you to replicate the change I linked for SAML to see the fastest support of this use case.

There are a lot of changes there and since Wazuh manages the configuration I am going to create a ticket in their project for now.
