Problems using "Integrated Security" w/Crystal Reports 11 and SQL Server 2005

Asked by: BlakeMcKenna

My shop has had problems using "Integrated Security" with Crystal Reports 11 ever since we installed CR 11. Our users logon to our network using an "Active Directory" logon. We use SQL Server 2005 as our backend DB and VB.Net 2005 as our development tool. Everything works fine from a Development machine or a stand-alone PC, but when installed on a Terminal Server....it craps out. For some reason, everytime a user goes to print a CR from within a VB.Net app, we get the "Database Logon" screen. See below.

Here is a code snippet of a typical call to a CR report. Currently, the "UserID/Password" parameters are commented out. It works on a stand-alone PC but still not on a Terminal Server.

Public Sub PrintStatusCodesListing()
        Try
            dErr.clsModule = "modReports"
 
            Dim crDoc As New rptStatusCodes
 
            With crConnectionInfo
                .ServerName = "HERCULES"
                .DatabaseName = "Drip"
                '.UserID = "testUser"
                '.Password = "password"                
                .IntegratedSecurity = True
            End With
 
            strFormula = "{tblStatusCodes.statusID} > 0"
 
            crDoc.RecordSelectionFormula = strFormula
            frmReports.crViewer.ReportSource = crDoc
            frmReports.crViewer.DisplayGroupTree = False
            frmReports.ShowDialog()
 
        Catch ex As Exception
            dErr.clsProcedure = "PrintStatusCodesListing()"
            dErr.clsMsg = ex.Message
            dErr.OnlineErrorHandler(dErr.clsModule, dErr.clsProgram, dErr.clsProcedure, dErr.clsMsg)
        End Try
    End Sub

When the user logons into a TS section do they become regular Windows users or do they have a different kind of account?  

Do they log into the same domain?

They logon to the same domain as a regular Windows User.

It should work unless something is the blocking the users.

What are some possibilities that would "block" users?

I note that your code is trying to connect to a server called Hercules, but the login window is trying to connect to a server called DRIP.

Are you connecting through a DSN? Is it set up for the wrong server by any chance?

 

by: BlakeMcKennaPosted on 2008-07-15 at 07:01:17ID: 22007065

Well, I wondered that too. I checked the File DSN and the Database it connects to resides on the HERCULES server, which is selected as a parameter. I believe that is just what I decided to call the DSN because that's the name of the Database it connects to.

Does anyone have any idea about this at all? I know this DB Logon prompt is an open issue with Business Objects and there are supposed work-arounds but I've yet to find one that works for my scenario.

Thanks,

Here's an idea: There's thing thing called a double hop.... when you try and pass a windows credential over a number of servers (i.e. > 2) it can get "lost along the way"

Its kind of explained here:

http://blogs.msdn.com/knowledgecast/archive/2007/01/31/the-double-hop-problem.aspx

The TS may be the extra server that makes it lose its window credentials.

It may explain why it doesn't work on TS but does in other environments.

Other than that I suggest you try using FileMon and RegMon on a wokring and non working case and see if there are any access issues.
