Windows Authentication user name in Power BI Server

[yelah3]

Hi, I uploaded .pbix file to the PowerBI Portal

the data is set by RLS and the credential of data source is set as Windows Authentication. 

but if I log into the portal, there's no data. 

I made a measure = username() card and it shows the name of the logged in windows account, and the data supposed to be filtered by the account(mydomain\myusername).

 

could anyone please help me with this?

windows auth is not going to work like you think it would since the account you are using to run the RS is the account that will show up in this particular case.
