SSRS and SharePoint Integration Authentication Issue

Question

We recently turned on SSRS for our SharePoint 2010 Test Environment.  We are using an account that has rights to SharePoint as a site collection administrator, the feature is enabled on the site collection and site level, it has access to the SQL instance
to pull the reports.  The report config file specifies NTLM authentication.  It acts as if it will configure and goes through the SP Central Administration steps successfully.  When I try to deploy a report, I receive the following error:
Exception encountered for SOAP method GetSystemProperties: System.Net.WebException: The request failed with HTTP status 401: Unauthorized.     at Microsoft.SqlServer.ReportingServices2010.RSConnection2010.SetConnectionProtocol()    
at Microsoft.SqlServer.ReportingServices2010.RSConnection2010.SoapMethodWrapper`1.ExecuteMethod(Boolean setConnectionProtocol) 1afe9dfd-9846-4194-bddf-fcb0ded634be

 0000 High     Exception encountered for SOAP method GetSystemProperties: System.Net.WebException: The request failed with HTTP status 401: Unauthorized.     at Microsoft.SqlServer.ReportingServices2010.RSConnection2010.SetCo
If I turn on trusted accounts, it works, but then it argues when the report loads because our reports use windows integrated authentication.  We would prefer to have windows integrated authentication to control who can see reports by their
login name.  Any ideas?  I feel like I have exhausted options.

Can you please elaborate on how to avoid using Kerberos and use the Secure Store to access our external SQL data? In our test environment, we have SharePoint 2013 Ent, SQL 2012 Ent. I am trying to use PowerView to access a Direct Query data model created
in SSAS tabular mode. My connection from SharePoint to the model is successful but fails with a reporting service error:
Cannot create a connection to data source 'EntityDataSource'.
