Thanks Ann, that might be the issue. Will have to onboard SonarQube on AWS SSO using SAML for it to have the same IDs to all the users. Came across Cloud applications - AWS Single Sign-On and looks like I can onbpard Sonar on AWS SSO now. Thaks for your response
Note that you can also associate SCM ids with existing accounts in SonarQube, but it’s a manual process - either for the admin or for each individual user.
