Relevant logs/screenshots

/cc @branden.cobb this current file does not seem to work with sonarqube. I suspect i need the certificate? Could you try this out:

The HelmRelease:

  values:
    hostname: bigbang.dev
    image:
      pullSecret: private-registry
    istio:
      enabled: true
    monitoring:
      enabled: true
    sonarProperties:
      sonar.auth.saml.applicationId: platform1_a8604cc9-f5e9-4656-802d-d05624370245_bb8-saml-sonarqube
      sonar.auth.saml.enabled: true
      sonar.auth.saml.loginUrl: https://login.dso.mil/auth/realms/baby-yoda/protocol/saml
      sonar.auth.saml.providerId: https://login.dso.mil/auth/realms/baby-yoda
      sonar.auth.saml.providerName: P1 SSO
      sonar.auth.saml.user.email: email
      sonar.auth.saml.user.login: login
      sonar.auth.saml.user.name: name
      sonar.core.serverBaseURL: https://sonarqube.bigbang.dev
  valuesFrom:
  - kind: Secret
    name: values
    valuesKey: sonarqube.yaml

But the SSO button doesn't redirect to p1 sso.
