Hey @vishwanihar and @shiva_sq
When connecting SonarQube to a case-insensitive LDAP setup, you should set the sonar.authenticator.downcase=true configuration in your $SONARQUBE_HOME/conf/sonar.properties file and restart your SonarQube server.
While not available through the UI, the POST api/users/update_login Web API (documentation linked in the footer of your instance) can be used to rename the logins of existing users so that duplicates aren’t made.
You can imagine a script that programmatically:
- Pulls the list of active users from GET api/users/search
- Extracts the username of each user object returned and checks if the username is already lowercase
- Uses POST api/users/update_login to update offending usernames to an all-lowercase version
