Hi,

I have an ASPX web form with a WebForms.ReportViewer on it.

I have created a new ReportServerCredentials class form this site
http://blogs.msdn.com/bimusings/archive/2005/11/18/494436.aspx

My code for the report viewer is:

rvBlackListReport.ProcessingMode = ProcessingMode.Remote;

rvBlackListReport.ServerReport.ReportServerUrl = new
Uri("https://www.MyDomain.com/ReportServer");
rvBlackListReport.ServerReport.ReportPath = "/MyReports/TestReport";

ReportViewerCredentials rvc = new
ReportViewerCredentials("TestUser", "TestPassword", "");
rvBlackListReport.ServerReport.ReportServerCredentials = rvc;

When trying to view the report I am receiving the error:

The request failed with HTTP status 401: Unauthorized.
* same user and password works fine on windows application.

Thanks in advanced for any help,
Asaf

Hello Asaf,

Thank you for posting.

As for the custom "IReportServerCredentials" implementation class, based on
my research, we should use the "NetworkCredentials" property to supply the
credential that will be used for authentication against the remote
reportServer. Here is a test ServerCredential class I used:

public class ReportViewerCredentials : IReportServerCredentials
{

private string _username;
private string _password;
private string _domain;

public Uri ReportServerUrl;

public ReportViewerCredentials(string username, string password, string
domain)
{
_username = username;
_password = password;
_domain = domain;
}

#region IReportServerCredentials Members

..........................

public System.Security.Principal.WindowsIdentity ImpersonationUser
{
get {

return null;
}
}

public System.Net.ICredentials NetworkCredentials
{

get {

System.Net.NetworkCredential nc = new
NetworkCredential(_username, _password, _domain);
CredentialCache cc = new CredentialCache();

cc.Add(ReportServerUrl, "Negotiate", nc);

return cc;

}
}

#endregion
}
======================================

========test page code=============
protected void Page_Load(object sender, EventArgs e)
{

ReportViewerCredentials rvc = new
ReportViewerCredentials("TestUser", "Password01!", "machinename");

rvc.ReportServerUrl = ReportViewer1.ServerReport.ReportServerUrl;

ReportViewer1.ServerReport.ReportServerCredentials = rvc;

}
=============================

Hope this helps.

Hello Steven,

I have tried your code but still I am getting the error:
"The request failed with HTTP status 401: Unauthorized"

I have tried also to use administrator user.
Strange that on windows forms app it working with no problems.

Is there something I need to configure at Web.config file?

Regards,
Asaf

Thanks for your response Asaf,

"401: Unauthorized" means there is not credential passed to server-side for
authentication or authentication failed. Have you checked the IIS log of
the reportServer application to see what's the log entry for those requests
(from your ASP.NET application). Also, my local test ASP.NET application
doesn't add any particular configuration entry in the web.config file. Just
use the code I provided to attach the ReportServerCredential...

Steven - how would you write a class that inherits an interface in VB.NET?
It seems that when I convert your code to VB I cannot do as you can in
C#...do you have a VB.NET solution?

thanks - Michael R.

Imports Microsoft.Reporting.WebForms

Public Class MyReportServerCredentials
Inherits IReportServerCredentials
'line states that classes can only inherit from other classes.

Public Sub New()
MyBase.New()

End Sub

Public ReadOnly Property ImpersonationUser() As
System.Security.Principal.WindowsIdentity
Get
Return Nothing
' Use default identity.
End Get
End Property

Public ReadOnly Property NetworkCredentials() As System.Net.ICredentials
Get
Return New System.Net.NetworkCredential("user", "pass", "domain")
End Get
End Property

Public Function GetFormsCredentials(ByRef authCookie As
System.Net.Cookie, ByRef user As String, ByRef password As String, ByRef
authority As String) As Boolean
authCookie = Nothing
authority = Nothing
password = Nothing
user = Nothing
Return False
' Not use forms credentials to authenticate.
End Function
End Class

I think I just found the answer. See this post, it's in VB.NET:

Hi Asaf,

Have you checked the reportServer application's IIS log to see whether it
provide any clues. Also, in my local test envrionment, my reportserver is
installed on the default IIS site with integrated windows authentication
(anonymous denied), and I'm correctly use the webform ReportViewer control
and the custom credential class I posted to access the reportServer. Also,
is it possible that the supplied account's username/password is incorrect
or doesn't meet the requirement(I tested use local accounts on the server
machines and even when authenticated failed, the reportViewer control will
inform me the account name which is denied for accessing the target
report). Have you tried it on any other machine?

Hello Steven,

I have called Microsoft support regarding this issue and this is what a
Microsoft representative sent to my Email as I understood there is a bug here.

"Thank you for contacting Microsoft Online Support Service. My name is… and
I will be assisting you with this service request.
We found that there is a problem in using the case number… and it was caused
by an issue in our case creation system we have taken actions to fix it."

Regards,
Asaf

Thanks for your followup Asaf,

Seems the error message is regarding on the case number association.
Anyway, during he sametime, I think you can still try those things I
mentioned in the previous message and inform the CSSsupport engineer on
this.
