Use multiple LDAP-Servers for failover scenario

We have two AD controllers for failover reasons. If one of them fails, the other server is used for authentication.
In sonarqube we have set both servers, e.g.

LDAP is configured for both servers, e.g.

Unfortunately, if you start sonarqube service and try to login, it fails.
This behaviour is also mentioned in the docs:
“Note that all the LDAP servers must be available while (re)starting the SonarQube server.”

Therefore, this feature can’t be used for failover scenarios.
We would like that sonarqube works, even if our primary server fails. Thus it will be more robust to failures and outages.

The configuration would already fit. Maybe some error handling needs to be adjusted.
