If Carousel support asks you if your Carousel system is integrated with a separate SQL server, or Active Directory and you’re not sure, simply log into Windows on your Carousel Server and navigate to TRMS\Configuration and open ConnectionStrings.config in notepad.
If the data source in the FrontDoor or Carousel entries is anything besides (local), then you are using a separate SQL server. If the LDAP connection string is anything besides LDAP://ad.example.com, then you are integrated with Active directory
