Archive link error:HTTP error: 401 Unauthorized

Hi all,
I am getting "HTTP error: 401 Unauthorized" error while uploading pdf via archive link store business document
from front end.
Any solution

Abhijit,
Check that the OS user that is used to run the web application has read/write permissions for the both the "installation path" and the "repository path" - for UNIX its the Apache user id and for Windows its the user that started the IIS service.
This may resolve your issue.

Dear Rosa,
Are you trying to post Expense reports to ERP System and you are getting this error?
Error Unauthorized (401) generally means the User ID in ERP backend maintained in outbound communication is not valid. Could you please check if the user is valid in ERP with the proper roles and its password is well maintained? If this is well maintained, Check Connection should return Ping Successful.

Error when accessing BHOLD Self Service (HTTP status 401: Unauthorized)

Hi,
I have started looking at the BHOLD suite and installed it on a server running FIM2010R2. The installation of the BHOLD suite seemed to be completed without problems and the BHOLD service are up and running under the B1User account and all BHOLD

However when I click on the link "BHOLD Self Service" in the FIM portal, the silverlight plugin starts and after a short while shows the following error message:

Could it be that the spn of the servername is already registered by the service account of FIM? A workaround that worked in the past was to
remove the spn from the fim service account and adding it to the b1user service account.
I've also seen it happening that the IPv6 hostname was different from the IPv4 hostname which causes the
HTTP status 401: Unauthorized issue.
I hope this helps.

Error "The request failed with HTTP status 401: Unauthorized"

Dear All,
While running ssrs report using reportviewer I am getting following error as "The request failed with HTTP status 401: Unauthorized". I have also added required entry in registry and rebooted the server. But same issue appears. So, please help
me to resolve this.
Thanks in advance

Hi dsddsadsa,
According to your description, when trying to running report from the report viewer control, the error "The request failed with HTTP status 401: Unauthorized" is thrown out.
While running report viewer control without impersonation setting, by default it will use the process identity which is Network Service (the AppPool identity is Network Service). Depending on the identity of the AppPool the app is running under, the identity
might be rejected. In your scenario, you may haven’t enable ASP.NET impersonation, you will get this exception. Please set up the following impersonation in the Web.config file, so that ASP.NET will use the configured user name and password to access the report
server:
<configuration>
<system.web>
<identity impersonate="true"
userName="domain\user"
password="password" />
Reference:

Web Service client authorization error: HTTP status 401

.NETters,
My .NET client program is invoking a simple "Hello World" Web Service written in ABAP. Here is the code:
Z_HWWSDServiceWse svc = new Z_HWWSDServiceWse();
try {
    string msg = svc.ZHelloworld();
    Console.WriteLine(msg);
}catch(Exception e) {
    Console.WriteLine(e.Message);
The code uses WSE 2.0 framework.
This code works if I edit the properties on WSD service using transaction SICF and specify anonymous login options. However, I would like to pass the user token from the client program itself.
So I removed anonymous login options and supplied the required information programmatically.
UsernameToken ut = new UsernameToken("pradeep", "password", PasswordOption.SendPlainText);
svc.RequestSoapContext.Security.Tokens.Add(ut);
However, when I run this code, I get an error: "The request failed with HTTP status 401: Unauthorized"
I then tried supplementing this code with network credentials logic:
System.Net.CredentialCache cc = new System.Net.CredentialCache();
cc.Add(new Uri("http://servermachname"), "Basic", new System.Net.NetworkCredential("pradeep", "password", null));
svc.Credentials = cc;
The problem still doesn't go away :-(.
Does anyone have any idea on what is it that I am missing in my code?
Thank you in advance for your help.
Pradeep

In my tests with normal .NET WS client something like the following allways worked:
WSProxy proxy = new WSProxy();
proxy.Credentials = new System.Net.NetworkCredential("user", "password");
proxy.PreAuthenticate = true;
proxy.CallMethod();
As your code is very similar, it may be a compatibility problem between WSE and WAS. I would recommend that you use a network snippen and look what really goes over the wire.
I have also seen an issue where the settings in SICF where somehow corrupted (e.g. the fixed credentials checkbock was on, but no credentials where specified). The solution was just to "reset" the settings in SICF.

Can someone let me know how to fix this.

jpmartop,
were you able to get this to work?
We have a 4 server topolgy.
moss
wfe
sql
ssrs
and are using Kerberos.
I've installed the wfe on the ssrs and am using a domain user for services, web and pools.
I get all green dots in the ssrs config.
in Central Admin, Grant access seems to work with the domain user, but set defaults gives me:
HTTP status 401: Unauthorized.
What should my web security on the default web site and reports and reports server look like? Integrated Security
Should the SSRS WFE entry in MOSS have Web application service turned on?
I've checked that my SPNs are good.I've installed sql server sp2 and a did windows update on all servers..
Could it be the user I log into the Central Admin with.. it's got server administrator and Farm administrator?
Thanks for any help or information.

"The request failed with HTTP status 401: Unauthorized"

Hi,
I'm trying to get both RSS feeds and SSRS reports on a web application which is having NTLM authentication without Kerberos. The catch is proxy setting, if I give <proxy autoDetect="false" /> in web.config of my sharepoint web
application SSRS reports will be rendered in SQL Server Report viewer perfectly (I deploy using BIDS), but RSS viewer webpart will not display my internet feeds. If I give
<proxy autoDetect="true" /> RSS feeds are displayed properly but SSRS report will throw the following error.

I tried to work around this by adding proxy settings with bypass list.
<system.net>

  <add address="http://<report server>:8080/reportserver/" />
  <add address="<IP of my report server>" />
      </bypasslist>
    </defaultProxy>
</system.net>
This makes RSS feed to work but SSRS throw the above error. I would need some advice from Microsoft on how to fix this.
Note: My sharepoint site cannot be anonymous. I have just once service account that runs sql server service, report service, sharepoint services etc. This account is local admin on all servers, has highest access on sql box, run SSRS web service and app
pools, etc.
I have four servers, 2 WFE in windows load balanced, 1 app server (running Central admin and report service in sharepoint integrated mode), 1 db server hosting all content and config dbs and report server db.

Manoj

Hi,
Thanks to share your post.
For the issue,
do you mean that the error happen with the use of NTLM authentication without Kerberos? If yes, the possible cause should be the lacking of Kerberos.
My suggestion is to implement the Kerberos authentication in your environment. You may check it and test it. For the detailed steps of implementing of the Kerberos:

SSRS 2012 - The request failed with HTTP status 401: Unauthorized.

I have SSRS Reporting Services 2012 load balanced on two servers.
Both servers are running Windows Server 2012 R2.
I have a Web Application that renders reports by utilizing this SSRS Reporting Services 2012.
When the application generates a report using load balancing I get error the message, “The request failed with HTTP status 401: Unauthorized.”
However, using only one reporting server, the application is able to render the report just fine.
It seems that when the requests are shared between the servers the problem occurs.
One solution is to configure Load Balancing with “Source IP” persistence.
This seems to work. I believe this is a “sticky” session.
With this Load Balancing configuration, the application can render the report just fine.
(However, I have not done complete testing.)
The problem occurs when calling the service ListChildren(string, bool ) on SSRS.
I have been researching online. I tried modifying the registry on the servers based on online articles (see below.)
Here are some articles I have looked at.
http://msdn.microsoft.com/en-us/library/cc281307(v=sql.110).aspx

http://blogs.msdn.com/b/lukaszp/archive/2008/07/18/reporting-services-http-401-unauthorized-host-headers-require-your-attention.aspx
Is there a better solution? Will Load Balancing with “Source IP” persistence be an acceptable solution? Is there a patch needed for the servers or SSRS? Please let me know.

Hi GoGladiator,
Generally, "The request failed with HTTP status 401: Unauthorized" occurs when
The service account used to connect to the Report Server is not authorized.
The Reporting Services is configured to use Kerberos, however, we didn't register Service Principal Name (SPN) for the account the Reporting Services is running under.
So, to fix this issue, we can refer to the follow steps:
Make sure the user is able to connect to the Report Server.
If using Kerberos authentication, please make sure SPN is configured correctly. If using Kerberos authentication, please make sure SPN is configured correctly.
For more information about Kerberos Authentication and how to register SPN for a report server in Reporting Services, please see the articles below:
Configure Windows Authentication on the Report Server
Register a Service Principal Name (SPN) for a Report Server
Hope this helps.

SQL Server Reporting Service 2008 R2 - The request failed with HTTP status 401: Unauthorized.

I got the error "The request failed with HTTP status 401: Unauthorized." when I call the Reporting Service Web Service.
The code is very simple:
// Initialise the reporting service Web Service
this.RSWebService = new ReportingService2010();
// Pass windos authentication credentials to Web Service
this.RSWebService.Credentials = System.Net.CredentialCache.DefaultCredentials;
// List children
List<CatalogItem> reports = this.RSWebService.ListChildren(folder, false).ToList();
The SQL Server is installed on a different machine (say server A) from the Web server (say server B). We are using Windows Server 2003.
The code work fine for all the scenario below:
i) Run locally (XP) to call the web service on the sql server
ii) Provide the Network Credentials with the username, password, and domain when calling the web service
iii) If the web server and sql server is using same server (i.e. not distributed)
I'm using windows authentication and impersonation. Any idea?

Hi Raymond,
If I understand correctly, the issue only happens in the environment that the web server is different with the SQL Server Reporting Services server. This means the web server is a remote server of the Report Server. Windows Integrated authentication is used
in this case. When running the web page, the 401 error occurs.
If so, it is actually a double hop issue. The double-hop problem will usually only be an issue to those of you who write some sort of web-based code (a web application or web service) that uses impersonation.
To fix the issue, we can configure kerberos authentication for the web application and the SQL Server Reporting Services.
Below is a great article that has delivered many solutions to fix the issue you met:
http://odetocode.com/articles/216.aspx
Additionally, you can read the following article to know more about double-hop:

Thanks Jin. I believe this is the cause of the problem as well.
I tried to register the SPN but unfortunately it still doesn't work. I'm not sure whether I'm using the correct SPN name.
I have 3 reporting server instance on the SQL box. So the Web Service URL is like
http://Server:80/VirtualDirectoryDev,
http://Server:80/VirtualDirectoryTest and
http://Server:80/VirtualDirectoryStaging .
What's the SPN I need to register?
I tried
Setspn -a http/Server:80/VirtualDirectoryDev domain\account
and
Setspn -a http/aerver:80 domain\account.
But both of them are not working :(

Service Clients failing with "The request failed with HTTP status 401: Unauthorized"

Hello,
We have implemented a solution using the SSRS web service clients as produced by the WSDLs. We have deployed the application on one server, and via the code we are calling the SSRS on another server (i.e., not using ReportViewer, etc.). We do
know that the user signed in has permissions since from the same staging server the Report Manager and Reports can both be accessed and viewed. However, it's only when we run the application and attempt to execute a report on the remote SSRS server that
we get the following error:
The request failed with HTTP status 401: Unauthorized. at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String
methodName, Object[] parameters) at AMC.AssetTracker.Reporting.ReportExecution.ReportExecutionService.LoadReport(String Report, String HistoryID) at AMC.AssetTracker.Reporting.Report.GetReportByteArray() at AMC.AssetTracker.Reporting.Report.get_ReportStream()
at AMC.AssetTracker.Reporting.Report.get_GetWebUIDisplay() at AMC.AssetTracker.UserControls.AssetTrackerMain.btnGenerate_Click(Object sender, EventArgs e)
The credentials we have tried are the DefaultCredentials. One question I have is how do you use custom credentials if neither the DefaultCredentials or the DefaultNetworkCredentials work? Also, this service call does have to go through an ISA
server before reaching the SSRS server.
Any ideas?
Thanks.

It sounds like Kerberos authentication is needed in your situation since it's not on the same box.
There is a one-hop limit with NTLM authentication.

Hi there,
Check the IIS logs on the web service server. Is the web page secured? What credentials are being passed to the web service? Turn on the report server trace logs and check them.
Some more info here, I find sysinternals.com tools very helpful in this case.
