Crystal Report 2011 Login prompt in asp.net - asp.net

Question

We are using Crystal Reports 2011 & SQL Server 2008 (Windows 7 64 bit). Whenever I try to deploy the crystal reports in the IIS it is always prompting enter the database login information. I have tried the below options
Set the login information in the code
Set IIS app pool to LocalService
Nothing works. Here is the code
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
ConfigureCrystalReports();
}
else
{
ReportDocument doc = Session["Report"] as ReportDocument;
SetLogon(doc);
CrystalReportViewer1.ReportSource = doc;
CrystalReportViewer1.RefreshReport();
}
}
private void ConfigureCrystalReports()
{
ReportDocument reportDoc;
if (!IsPostBack)
{
reportDoc = new ReportDocument();
reportDoc.Load(Server.MapPath("~/Sample.rpt"));
Session.Add("Report", reportDoc);
}
else
{
reportDoc = Session["Report"] as ReportDocument;
}
SetLogon(reportDoc);
CrystalReportViewer1.ReportSource = reportDoc;
CrystalReportViewer1.RefreshReport();
}
private void SetLogon(ReportDocument reportDoc)
{
var connectionInfo1 = new ConnectionInfo()
{
ServerName = #"ODBCDSN",
DatabaseName = "hrdw_old",
IntegratedSecurity = true
};
SetDBLogonForReport(connectionInfo1, reportDoc);
}
private void SetDBLogonForReport(ConnectionInfo connectionInfo1, ReportDocument reportDocument)
{
Tables tables = reportDocument.Database.Tables;
foreach (CrystalDecisions.CrystalReports.Engine.Table table in tables)
{
TableLogOnInfo tableLogonInfo = table.LogOnInfo;
tableLogonInfo.ConnectionInfo = connectionInfo1;
tableLogonInfo.ConnectionInfo.Type = ConnectionInfoType.SQL;
table.ApplyLogOnInfo(tableLogonInfo);
}
reportDocument.SetDatabaseLogon(connectionInfo1.UserID, connectionInfo1.Password);
}
}
Steps tried in IIS:
Application pool: ASP.NET 4.0 Default app pool
Also enabled Windows Authentication in IIS & disabled anonymous authentication.
Tried anonymous authentication only.
SQL Server has both windows and sql server authentication.
I will not be able to use dataset since the crystal reports will be developed by someone using command objects. It works perfectly good in the Visual studio 2010 environment. But doesnt work in IIS.
Am I missing something basic? Any help is appreciated.
Thanks

Here is how this was solved. It was a bit of workaround
CrystalDecisions.ReportAppServer.ClientDoc.ISCDReportClientDocument rptClientDoc = doc.ReportClientDocument;
CrystalDecisions.ReportAppServer.ClientDoc.ISCDReportClientDocument rcd = rptClientDoc;
string server = #"<SERVER>";
string db = "<DATABASE>";
string user = "<USER>";
string pass = "PASSWORD";
rptClientDoc.DatabaseController.LogonEx(server, db, user, pass);
//Create the logon propertybag for the connection we wish to use
CrystalDecisions.ReportAppServer.DataDefModel.PropertyBag logonDetails = new CrystalDecisions.ReportAppServer.DataDefModel.PropertyBag();
logonDetails.Add("Auto Translate", -1);
logonDetails.Add("Connect Timeout", 15);
logonDetails.Add("Data Source", server);
logonDetails.Add("General Timeout", 0);
logonDetails.Add("Initial Catalog", db);
logonDetails.Add("Integrated Security", "false");
logonDetails.Add("Locale Identifier", 1033);
logonDetails.Add("OLE DB Services", -5);
logonDetails.Add("Provider", "SQLOLEDB");
logonDetails.Add("Use Encryption for Data", 0);
//Create the QE (query engine) propertybag with the provider details and logon property bag.
CrystalDecisions.ReportAppServer.DataDefModel.PropertyBag QE_Details = new CrystalDecisions.ReportAppServer.DataDefModel.PropertyBag();
QE_Details.Add("Database DLL", "crdb_ado.dll");
QE_Details.Add("QE_DatabaseName", db);
QE_Details.Add("QE_DatabaseType", "OLE DB (ADO)");
QE_Details.Add("QE_LogonProperties", logonDetails);
QE_Details.Add("QE_ServerDescription", server);
QE_Details.Add("QE_SQLDB", "True");
QE_Details.Add("SSO Enabled", "False");
CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo newConnInfo = new CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo();
CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo oldConnInfo;
CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfos oldConnInfos;
oldConnInfos = rcd.DatabaseController.GetConnectionInfos(null);
for (int I = 0; I < oldConnInfos.Count; I++)
{
oldConnInfo = oldConnInfos[I];
newConnInfo.Attributes = QE_Details;
newConnInfo.Kind = CrystalDecisions.ReportAppServer.DataDefModel.CrConnectionInfoKindEnum.crConnectionInfoKindCRQE;
try
{
rcd.DatabaseController.ReplaceConnection(oldConnInfo, newConnInfo, null, CrystalDecisions.ReportAppServer.DataDefModel.CrDBOptionsEnum.crDBOptionDoNotVerifyDB);
}
catch (Exception ex)
{
Label1.Text = ex.Message;
return;
}
}
doc.SetDatabaseLogon(user, pass);
To ensure that there is no login prompt at all at first I had to login to the controller and then set all the login credentials. Ensure that login credentials are reused during post back as well. After this is done, login using the reportdocument as well. This solves the issue of login prompt coming again and again.
