Multiple connectons fails

Question

Hello, I am having a problem connecting. I am using CR2008 SP0, VB2008.  the report has two different ODBC connection and a subreport that has yet another connection.  The code..
'Load Report
CRReport.Load("C:\Users\Main\Desktop\" & "ConnectionTest3.rpt")
Dim conn As CrystalDecisions.Shared.IConnectionInfo
'Connection 1
conn = CRReport.DataSourceConnections.Item(0)
conn.IntegratedSecurity = False
conn.SetConnection("Data1", "Database1", "SA", "PW")
'Connection 2
conn = CRReport.DataSourceConnections.Item(1)
conn.IntegratedSecurity = True
conn.SetConnection("Data2", "Database2", True)
'SubReport
Dim mySubreport As ReportDocument = CRReport.OpenSubreport("SUB3.rpt")
conn = mySubreport.DataSourceConnections.Item(0)
conn.IntegratedSecurity = False
conn.SetConnection("Data5", "Database3", "sa", "PW")
'Display Report
myCrystalReportViewer.ReportSource = CRReport
What I get when I run the project there is a logon failure for the sub report logon. I type the correct PW and then it continues. You will notice that the second connection uses a trusted connection, if set that to use a non-trusted connection as in conn1 the report runs great. if I strip out the sub report the main report runs fine.  If I only run the sub report it run fine.
Can you mix connection types in .net?  Am I missing some code for the subreport?  
Thanks for any and all help!

Hello Patrick
I was able to duplicate the issue. I will be submitting it for a resolution to R&D today. Now, here is where things get... "interesting". If this is accepted by R&D, a fix will most likely not be out for at least 6 months.
I did try to find work-around for the issue (other than not use NT security) and I found out that as long as the trusted connection is the last connection established - in the designer - then this will work. E.g.;
New report
Add SQL connection to datasource A (SQL security)
Add subreport and set the subreport to datasource C (SQL security)
Go back to the main report and add datasource B (NT / integrated security)
I believe the issue is due to the trusted connection being propagated to the subreport and doing the above steps forces the trusted connection to be established last and thus there is nothing to propagate. E.g.;
1) connect to ds A
2) connect to ds C
3) connect to ds B (trusted) - last connection = nothing to propagate
As long as the trusted connection is the last connection to be added, the reports work.
Working with the code to try and get to change the connection order at runtime does not work - as we already found out from my suggestion in one of the earlier posts.
As soon as I have the Technical Escalation number, I will update this thread.
