Power BI
Under ReviewSecurity - Ability to maintain source security for reports published on BI Sites

The general requirement is that visualizations (Power View, SSRS etc...) must not circumvent existing policies, or introduce yet another set of security policies on top of those already implemented at the source.
* For example, a visualization of sales data needs to reflect the policy that account managers can only read sales data for their region.
* For performance reasons, this is enforced at the source by injecting predicates into the query based on the end users identity. If identities for end users are not passed down the process chain into the data layer, it leaves us little option but to publish individual reports for every region, which results in an explosion of complexity and numbers of reports, or move the whole model to BISM and manage the policy in yet another place (namely the BISM model).
Impact
blocking migration to SPO/BI Sites. At least 412 Site Collections with more than 600 Power Views. Impacting Adoption or migration for majority of BPUs - e.g. Finance, LCA, HR, etc

Hey all! We've continued to make progress here, so I wanted to update this thread with our current capabilities for maintaining security on dashboards/reports. As always, all of this information can be found in our Row-Level Security (RLS)documentation: https://powerbi.microsoft.com/en-us/documentation/powerbi-admin-rls/ > If you have set up RLS in Analysis Services, Power BI will send the signed-in user's credentials to Analysis Services, and respect the RLS rules set up on the on-premises model. > Separately, you can set up RLS in Power BI for data sources that you import or connect to via DirectQuery. This process starts in PBI Desktop, where you define roles, and write DAX to constrain what data these roles can see. As part of this process, can you use the UserPrincipalName () DAX function to get the current signed in user's UPN (e.g. joe@contoso.com). Then, once you publish to service, you can assign users to these roles. Does the above meet your requirements? Please let us know via comments or e-mail. Those of you who requested that the identity of the signed in Power BI user be pass through to Azure SQL, SQL DB, DWH, etc.: we hear you - that is under consideration. Thanks, -Sirui

Good information, thanks

Thanks

Importantly when the RLS Security is enabled and the workbook has been downloaded to PBI Desktop by an end user they should not be able to edit the security configuration setup.
RE: Security - Ability to maintain source security for reports published on BI Sites
We are using an Odata feed to CRM Online and to mimic the entire security model already customized in CRM is not very practical.
RE: Security - Ability to maintain source security for reports published on BI Sites
Agreed - we are also looking at RLS and through desktop, definately slows things down. There needs to be better ways to link back to DB.
RE: Security - Ability to maintain source security for reports published on BI Sites
We really need the ability to connect to an SQL database with AD authentication for a live gateway connection when publishing to the web. PowerBI has this feature on the desktop, it should work on the web as well.

We've implemented RLS using DAX. The queries run 10 times slower. It appears that all of the data is returned to the client and then DAX filters it. To get the performance we need, we have to have the identity passed through to SQL Azure RLS via session_context.
RE: Security - Ability to maintain source security for reports published on BI Sites
Hi Sirui,
Any update on identity pass through to Azure SQL. We know it is under consideration, but we need to know if it will be implemented.
Thanks,
Tim

I'd love to see this expanded to respect the SQL security using pass through auth and Azure Active Directory. When using services like SQL Azure, the security model can then be built in the database - agnostic of the reporting tool on top.
RE: Security - Ability to maintain source security for reports published on BI Sites
If I build a single report to which is applied some Row-level security, does the end-user need to buy some « application »/ « plugin » to visualize only the data he is allowed to see ?
If not, how can we pass along his identity to the back end ?
