I am new to OpenStack and recently I am learning to use it. After I successfully install OpenStack by following this link: https://www.ubuntu.com/download/cloud/try-openstack
At 3rd step, it said, "default username “admin” and password “OpenStack”. However, when I entered the dashboard, I saw 3 entries: domain/username/password. Please see the screenshot of dashboard
I cannot leave the "domain" with a blank but I really don't know what "domain" it is here. I searched online and only found some infos about functionalities about the domain of OpenStack.
Please help! Any suggestions will be appreciated!
