PowerBI Service Kerberos connection

Hi,

I am connecting PBI service to an on prem Analysis Services tabular model and an on prem SQL Server database.

I have some dynamic row level security implemented in the AS model and directly with roles in PBI reports with SQL connections.

Apologies for the ingnorance, but I am trying to understand whether implementing Kerberos would help. 

I assume the benefit for the SQL reports would be that I could pass through the user name and therefore implement RLS on the SQL Server (and not need to do it in each report)?

For the tabular connections, the roles pick up the effective user name, so would there be any change/ benefit for these connections?

Thanks for any pointers!
