Crystal Subreport prompting for login

Question

When running an app that shows a crystal report that has subreport, the user is prompted for login information.

Below is my code I am using to pass the login information to the report. This code is executed when the form is shown. I have a test vs2017 app that contains a form with a crystal report viewer on it. The login information is passed and works fine until I add a subreport. Once a subreport is added to my existing report the user is prompted to log into the database. Upon entering the correct login credentials, a login failed message appears. The report cannot be run. The report gets data from a command query from the database.

    Sections crSections;
    ReportDocument crReportDocument, crSubreportDocument;
    SubreportObject crSubreportObject;
    ReportObjects crReportObjects;
    ConnectionInfo crConnectionInfo;
    Database crDatabase;
    Tables crTables;
    TableLogOnInfo crTableLogOnInfo;
    crReportDocument = new ReportDocument();
    crReportDocument.Load(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, CrystalReport3.rpt"));
    crDatabase = crReportDocument.Database;
    crTables = crDatabase.Tables;
    crConnectionInfo = new ConnectionInfo();
    crConnectionInfo.ServerName = "myservname";
    crConnectionInfo.DatabaseName = "mydatabasename";
    crConnectionInfo.UserID = "sa";
    crConnectionInfo.Password = "myusername";
    foreach (CrystalDecisions.CrystalReports.Engine.Table aTable in crTables)
         {
         crTableLogOnInfo = aTable.LogOnInfo;
         crTableLogOnInfo.ConnectionInfo = crConnectionInfo;
         aTable.ApplyLogOnInfo(crTableLogOnInfo);
         }
         // THIS STUFF HERE IS FOR REPORTS HAVING SUBREPORTS 
         // set the sections object to the current report's section 
         crSections = crReportDocument.ReportDefinition.Sections;
         // loop through all the sections to find all the report objects 
         foreach (Section crSection in crSections)
             {
             crReportObjects = crSection.ReportObjects;
             //loop through all the report objects in there to find all 
 subreports 
             foreach (ReportObject crReportObject in crReportObjects)
                 {
                 if (crReportObject.Kind == ReportObjectKind.SubreportObject)
                 {
                     crSubreportObject = (SubreportObject)crReportObject;
                     //open the subreport object and logon as for the general report 
                     crSubreportDocument =                crSubreportObject.OpenSubreport(crSubreportObject.SubreportName);
                     crDatabase = crSubreportDocument.Database;
                     crTables = crDatabase.Tables;
                     foreach (CrystalDecisions.CrystalReports.Engine.Table aaTable in crTables)
                     {
                         crTableLogOnInfo = aaTable.LogOnInfo;
                         crTableLogOnInfo.ConnectionInfo = crConnectionInfo;
                         aaTable.ApplyLogOnInfo(crTableLogOnInfo);
                     }
                 }
            }
         }
    crystalReportViewer1.ReportSource = crReportDocument;
    crystalReportViewer1.Refresh();

I expect the report to be run without prompting the user as I am passing in login credentials.
