Power BI Embedded - Connection to Analysis Services Tabular

We want to use Power BI Embedded but cannot until it supports live connections to SSAS. Can we please get a timeline on when when this feature will become available? Until the feature above becomes available, we would use a different approach which is also problematic. We have many users that want to connect to our SSAS but we do not want to put them on our local domain controller. We only want them to have Azure AD. In order to give them access to the cubes and apply permissions properly, we need to use CUSTOMDATA () . The "Map User Names" feature seems to do what we need but we have a few issues with it. (A) It requires all the usernames to be entered manually into each gateway connection. This is a lot of manual work. Being able to do this from the REST API would really help us streamline this process. (B) The mapping seems to take only the first rule that applies. I'm not sure if this is by design. The documentation doesn't explain it. We would like to be able to apply multiple rules to the same username so that we can map it to multiple permissions (e.g. location, department etc.)
