Connecting to Azure Analysis Services with same user

I have an Azure Analysis Services tabular model.   I'm able to connect to it from PowerBI.com.  And I know how to give others access to it by creating an AD user for them and adding them to a Analysis Services role.  However, I was wondering if there is a way to allow users to access PowerBI reports that use the Analysis Services model without having to giving them direct access to the DB.   Would there be a way to set the credentials up so that they always use the same AD account to authenticate with Analysis Services?

Thanks!
