Not able to Access Shared Folder from SQL Server using SSIS

I have created a OLE DB Connection and Created a Flat File Connection pointing to a Shared Folder Location.
When i execute in BIDS, its working fine in placing the file, But when i deploy the code in SSISDB, its errors out, "Cannot Open Datafile", Access Denied

We are using SSIS 2012 and executing the package through stored procedure.
