Forms authentication - Object reference not set to an instance of an object

I have successfully implemented forms authentication, that means, I can access it from a web browser, get the login page, add my credentials and log on to Reporting Services.

But now I try to access reporting services Web service from a winforms app, doing something like this:

ReportingService _rs =newReportingService();

_rs.LogonUser("myUsername","myPassword","");

_rs.Url ="http://myServer/ReportServer/ReportService.asmx";

CatalogItem[] items = _rs.ListChildren("/",true);

The first three lines works fine, but he last line (ListChildren) throws a "Object reference not set to an instance of an object" exception. I have enabled remote error and looked in the RS log files, but nowhere I can find where this null-pointer exception occured.

Any idea about where to go from here?

Regards Andreas

Completing information...

I have checked the SQLDUMPER_ERROR.log file, and it contains the following, regarding this problem:

And the file SQLDmpr001.mdmp contains the following regarding the problem:

So, it seems like the method ConstructRSServiceObjectFromSecurityExtension()

throws a NullReferenceException.

But why? I'm really stuck... =(

It is probably a configuration issue. Verify the configuration steps. You may find the following article useful.

TeoLachev at 2007-9-12 >

# 3

The article references to the readme-file for configuration:

Since the most difficult part in implementing custom security is configuring the security extension properly, detailed step-by-step instructions are provided in the readme.htm file. In addition, you can find copies of the report manager and report server configuration files in the Configuration Files folder. Please use these files as reference only! Do not just copy them and replace your configuration files.

And it's the readmefile I have followed while implementing. I have also double checked it several times to check so that all should be ok. Ofcourse I can have missed something anyway. Do you have any ida of witch configurationfile most probably causes such an error? These are the files I have modified:

...\ReportManager\rsmgrpolicy.config

...\ReportManager\RSWebApplication.config

...\ReportManager\Web.config

...ReportServer\rsreportserver.config

...ReportServer\rssrvpolicy.config

...ReportServer\web.config

Unfortunately, I can't tell. One thing you can try just to rull out errors in your code is to put a breakpoint inside the SetConfiguration method of the Authentication class and see if it is hit when you debug. If it isn't, most likely is a a configuration issue.

TeoLachev at 2007-9-12 >

# 5

I think I solved the problem and thought I should post it here, in case anyone else runs into the same issue.

The problem was that since I use custom authentication in RS, I needed to inherit the 'ReportExecutionService' class and implement 'GetWebRequest', 'GetWebResponse' and 'AuthCookie'. I stole the implementation code from the RS forms authentication example, but I can't say I fully understand what I have done...

At least It made my null-pointer exception go away, and now I can call the web service without problem!

Since the web request to LogonUser originates on the server side the cookie won't be sent to the browser by default (it is a double hop). These two methods relay the cookie from the server to the client and are absolutely necessary so the cookie is transmitted successfully.

TeoLachev at 2007-9-12 >

# 7

I'm having the same problem. I have traced my Authentication code and know that it is working, however, I keep getting these errors in the Reporting Service log directory. The web interface is working, including all the security, but when these error occur the interface hangs until the dump is processed.

Did you find a fix for this issue? I am have the same problem. The report server will run but I get the same error in my log files and it hangs until the core dumps, which happens 4 times.

DanMan226 at 2007-9-12 >

# 9

No such luck. As you say everything works except for the hang and the logging of a dump.

I setup a separate machine with Windows Server 2003, SQl Server 2005 with Reporting Services and Visual Studio 2005. I applied all the available patches and I have traced every line of my code through my forms auth dll and it works. I have no idea what is causing the dump. All I find on the various message boards is that it MUST be a configuration error but there is no information on what configuration might be in error.

We should be happy that we got this working at all. My manager just returned from Tech Ed and he says that everyone was complaining that they could not get SSRS Forms Authorization working.

If you find anything please post a note here. I'll do the same.

Ron(DI) at 2007-9-12 >

# 10

I have a case open with Microsoft right now. They are looking at my dump file to see what is causing the error. I will post the results when I know more.

DanMan226 at 2007-9-12 >

# 11

Well, as I said in an earlier post, my problem was that 'GetWebRequest', 'GetWebResponse' and 'AuthCookie' wasn't implemented in my code. Post your implementation of it here in the forum and perhaps I or someone else could find something there?

I can login to the SSRS web site, and run reports.

The first time I try to access the report manager I get 4 core dumps, null reference exception error, yet the site works after that. No core dumps. The report server service doesn't generate any errors, just report manager. The UILogin.aspx.cs file does implement the web request methods. The code is posted below.

Did you have to make any changes to the sample project to get it to work when you first implemented forms authentication?

Any update on this, It's occurring on my set up too and it's causing much angst.

Here is the response I have from Microsoft so far. I didn't have named pipes and TCP/IP turned on, but enabling both didn't fix the problem. I am waiting for another response. I also programatically set HttpOnly to false in the code and it is not fixed. I am now getting two memory dumps instead of 4 but no luck. The dump stack tracy file be reference is at the bottom.

I posted parts of my config file below to see if they match. The parts I updated are in yellow.

Microsoft Response

System.NullReferenceException - Object reference not set to an instance of an object. 3 common causes

1) Note, regardless of the scenario, the cause is always the same in .Net: You are trying to use a reference variable who's value is Nothing/null. When the value is Nothing/null for the reference variable, that means it is not actually holding a reference to an instance of any object that exists on the heap. You either never assigned something to the variable, never created an instance of the value assigned to the variable, or you set the variable equal to Nothing/null manually, or you called a function that set the variable to Nothing/null for you.

2) You never created a new instance of an object.

3) You created the object, but killed it too soon.

The cause is that a variable is used in code, but that variable doesn't contain a reference to any object in memory. If you try to call .ToString() on an object, and your variable is null, you'll get this exception. Sometimes it can be hard to figure out what's going on, but if you look at your stack trace, you can find out what method this Exception came from. Then, debug through that method and find the offending variable.

I have attached the dump stack trace in the text file which is attached with this email.

So I would like you to once again verify the steps which has been used for creation of forms authentication.

Here is couple of action plans other than described above.

=================================================

Check whether the SQL Server is configured to use named pipes and TCP/IP.

The problem could happen, so set the HttpOnly attribute for the session cookie to the false value in global.asax file.

Note Setting the HttpOnly attribute to the true value does not prevent a malicious user from accessing the cookie directly when the malicious user has access to the network channel. Consider using Secure Sockets Layer (SSL) to help protect against this. Workstation security is also important. A malicious user may use an open browser window or a computer that contains persistent cookies to access a Web site by using a legitimate user's identity.

To set the HttpOnly attribute to the false value, replace the Session_Start method in the Global.asax file by using the following code. void Session_Start(object sender, EventArgs e)

{

if (Response.Cookies.Count > 0)

{

foreach (string s in Response.Cookies.AllKeys)

{

if (s == System.Web.Security.FormsAuthentication.FormsCookieName || s.ToLower() == "asp.net_sessionid")

{

Response.Cookies.HttpOnly = false;

}
