Hi,

Uploaded SSRS report into Sharepoint 2010. When I tried to run the report, getting below error.

Cannot impersonate user for data source 'ds_Risk_Mgt'. (rsErrorImpersonatingUser)
This data source is configured to use Windows integrated security. Windows 
integrated security is either disabled for this report server or your report server
 is using Trusted Account mode. (rsWindowsIntegratedSecurityDisabled) 

Please help on this.

Regards,

Ramesh
