power bi on-prem, using RLS or etc. with regular sql query (non ssas)

Hi,

We have tried to implement 'Row Level Security' in Power BI On premise-solution, this has worked on desktop but after we published the report to server it didn’t worked.

i think we have faced similar issue with this http://community.powerbi.com/t5/Report-Server/Row-Level-Security-in-Power-BI-Report-Server/m-p/311546/highlight/true#M2550

and then unfortunately we found that RLS is not supported in the current version : http://community.powerbi.com/t5/Report-Server/Row-Level-Security-with-Direct-Query-not-SSAS/m-p/312299#M2574

But we have live reports that we used RLS on non-prem version. Has anyone know when RLS will be supported on this version? Or is there any other workaround solution?

We have trying to get Users whose Location information is same with the group on the Groups table and Groups.User is the person who opens the report (USERNAME() function doesn't supported somehow)
