Could you please let us know what version of OpenShift you are using and what is your primiary Identity Provider (IdP) ?
If you are using RedHat SSO / Keycloak as the primary identity provider (IdP), you can integrate SonarQube with IdP using OpenID Connect.
Please use the following SonarQube plugin for OpenID Connect (OIDC) integration.
You will have to create an openid connect client in RedHat SSO/Keycloak and then configure the SonarQube OIDC plugin with those credentials .
In summary, if your primary identity provider supports OpenID Connect (OIDC) integration, you can integrate SonarQube with IdP using the SonarQube OIDC plugin
If you need more information, please let us know.
