Hi, I am trying to implement AIO with Trove enabled using Packstack on Centos 7. My installation is successful, but when I try to list databases, it gives me "Error: Unable to retrieve database instances." When I check trove controller logs, I see this, 2017-11-22 15:47:34.070 21608 ERROR keystonemiddleware.auth_token [-] Bad response code while validating token: 400: BadRequest: Expecting to find domain in project.

Was I supposed to do more config? What could be issue here? Also, is there any link for pre-made guest trove images for mongodb and mysql? Regards, /Sonali
