I have a Web App server (WAS) and a database server (DBS). I need to know how to configure both servers, changes to make in the web.config, and any changes to the database needed to allow Windows Authentication from WAS to DBS. I know Kerberos needs to be setup and I know SPNs will need to be created, but I am not sure what all needs to be done.
View 1 Replieshow to implement kerberos authentication in asp.net. Pros & Cons of this authentication process.
View 1 RepliesI am trying to connect to a web service that uses Kerberos Authentication to authorize the user, but all I get is a 401 unauthorized everytime I try to make the request. Below is the code that I am using.
public XPathNavigator GSASearch(string url, string searchString)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url + searchString);
request.CookieContainer = new CookieContainer();
request.Credentials = CredentialCache.DefaultCredentials;
request.ContentType = "text/xml";
request.Method = "POST";
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream receiveStream = response.GetResponseStream();
XPathDocument doc = new XPathDocument(receiveStream);
return doc.CreateNavigator();
}
EDIT: I feel I should explain a bit more what I am attempting to do. I have been tasked with providing a new interface for my company's Google Search Appliance. I am using an ASP.NET page, which does some things like choose a Collection depending on where a user is located, etc. and then sends the appropriate search string the the GSA. This was all working well until they decided to turn authentication on, and now I can't get any results (I either get a 401 unauthorized, or a message stating that 'Data at the root level is invalid'). If I take the search string and provide it directly to the GSA, it authenticates fine, and displays the results, I just can't seem to get it through the HttpWebRequest.
EDIT 2: I did a little more looking (ran the request through Fiddler) and it looks like the request is only attempting Negotiate and not Kerberos. I set the credentials to use Kerberos explicitly as below, but it didn't help...
public XPathNavigator GSASearch(string url, string searchString)
{
CredentialCache credCache = new CredentialCache();
credCache.Add(new Uri(url), "Kerberos", CredentialCache.DefaultNetworkCredentials);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url + searchString);
request.CookieContainer = new CookieContainer();
request.PreAuthenticate = true;
request.Credentials = credCache;
request.ContentType = "text/xml";
request.Method = "POST";
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream receiveStream = response.GetResponseStream();
//StreamReader readStream = new StreamReader(receiveStream);
XPathDocument doc = new XPathDocument(receiveStream);
return doc.CreateNavigator();
}
EDIT 3: Ok, looking closer again, the CredentialCache.DefaultCredentials doesn't appear to have my network credentials in it...
I'm trying to setup an internal website that will contact another backend service within the network on behalf of the user using a HttpWebRequest.I have to use Integrated Windows Authentication on the ASP.NET application as the backend system only supports this type of authentication.
I'm able to setup IWA on the ASP.NET application, and it's using kerberos as I expect it to. However when the authentication is delegated to the backend system it doesn't work anymore. This is because the backend system only supports kerberos IWA, but the delegation for some reason - even though the incoming request is kerberos authenticated - converts the authentication to NTLM before forwaring to the backend system.
what I need to do on the ASP.NET application in order to allow it to forward the identity using kerberos?I've tried the following but it doesn't seem to work
CredentialCache credentialCache = new CredentialCache();
credentialCache.Add(request.RequestUri, "Negotiate", CredentialCache.DefaultCredentials.GetCredential(request.RequestUri, "Kerberos"));
request.Credentials = credentialCache;
I've also tried to set "Kerberos" where it now says "Negotiate", but it doesn't seem to do much.
I am using Kerberos as the Authentication mode for a WCF Client to interact with an ASMX Web Service. I am using customBinding in the WCF Client. I am getting the below mentioned Fault Exception when I invoke the HelloWorld Method by creating a Proxy using SVCUTIL.
`System.Web.Services.Protocols.SoapHeaderException: Server unavailable, please try later ---> System.ApplicationException: WSE841: An error occured processing an outgoing fault response. ---> System.Web.Services.Protocols.SoapException:

I am badly struck with this exception and unable to progress further.
What's the difference between Basic Authentication and Integrated Windows Authentication in IIS?

View 2 RepliesWe have a working version of application (Intranet) with uses Windows Authentication deployed in Windows 2003. The application uses HttpContext.Current.User.Identity.Name to get the logged-in user. Here impersonate is turned off.Right now, we are move to Windows 2008 RC2 where this Windows Authentication problem arised. I have Digest Authentication and Windows Authentication enabled. And also I have enabled Anonymous Authentication enabled to avoid the Login dialog of IIS in the end-user IE. Now I am getting HttpContext.Current.User.Identity.Name as Empty. When I impersonate using username and password, I am used to login using that user but all the users uses the same user to login.Does any has solution for this?Deployment Server - Windows 2008 RC2 (IIS 7.5)Development - Windows 7 (IIS 7.5)I am new to IIS 7.5.

View 3 RepliesI am developing one intranet website. Being an intranet application, one of the requirement is to have a single sign on feature.
It means that the windows PC username (i.e the "ctrl + alt + delete" username) is going to be the username for the system.
How do i fetch that username?
I tried the following two ways which are working in debug mode but not on live site.
System.Security.Principal.IPrincipal user = System.Web.HttpContext.Current.User;
Response.Write(user.Identity.Name);
&
Response.Write(Request.ServerVariables["AUTH_USER"].ToString());
Both the above method works when i run the page from visual studio.
However when i run the page from IIS or any other server, it gives me a blank value
I have to invoke SSIS packages from web service in the most secure way. I think that windows authentication will be secure but i am not sure. I do not have much knowledge about how to achieve this and the information on the internet is very distributed.
View 1 RepliesWe use Sharepoint to control our websites. We build the sites, then load them into the sharepoint server. My question is if I use windows authentication, how can I get my role security in my web config file to coencide with the asp.net controls that use the Forms authentication. Is there a differenence? Our security uses a session variable for security but there is no where to set up their permissions except in active directory. I hope this makes sense because I would like to implement the LoginView with Role groups but how can I give them the role="administrator"? Do I have to go into active directory and give them these permissions(would take awhile due to the size of the company)? Or do I have to set up priveladges in the web.config file for each user(difficult I think)?
View 5 RepliesI'm writing a simple Intranet application using windows authentication. I want to restrict access to Safe/UCantSeeMe.aspx. I am aware of the AuthorizeAttribute, but this only works on methods. I also found a good post on doing this with the MVC pattern, but I'm not using MVC. This can be done with roles in forms based security. I read on MSDN that using windows based security means roles are based on groups, but it doesn't go into any detail. how can I restrict access to Safe/UCantSeeMe.aspx?

I tried to develop the asp.net 3.5 by using the windows authetication and it seems to work fine. I had tried this code on my machine (local iis6):
Response.Write(User.Identity.Name.toString());
It returned correctly "my windows login usernameDomainname" however, I tried to deploy it on the windows server 2008, it returned "computer name/Administrator" Then, I tried to access this page from my computer which was redirected to 401 error. Moreover, I looked for the system property which showed that this server and my machine are on the same domain group.
I want to know if this kind of authentication is possible.
We have an Active Directory account and that account we are using to log in to windows. I have a simple system that needs authentication using the IIS log in box (i dont know what do you call this but what I know is it only comes out when Anonymous user is unchecked in the IIS configuration.) Now, I want this box to appear before my page and the user will be authenticated and be compare to the user who logged in to the windows. If the user who have been authenticated is the same as the user who logged in to the windwos then we will let him in if not he must be denied in accessing the page.
The first problem I have in my mind is how to code it in asp.net to make an authentication when he will try to access my page.
Second is, let us say we have succeeded to show the authentication box, how can I get the username from the log in box and compare it to the user who logged on in windows. Of course we can get the user id of the logged in user from the windows using User.Identity.Name but how about the username from the log in box.
Note: I will not use log in forms even using https. Just the log in provided by the IIS according to the configuration.
What I want to do is, if userA access the website, then the website will use userA's token to access the SQL server. Site is an intranet site.In web.config,I have
<authentication mode="Windows"/>
<identity impersonate="true"/>
Connection string:Data Source=sql;Initial Catalog=xxxxxx;Integrated Security=SSPI;persist security info=False;
IIS:Annoymous login is disabled, Windows authenication is enabled.
SQL server:userA is added as a user to the database.
IIS and SQL server are on different server. Running as userA on another computer, I try to access the website. The website log told me the website was trying to login to the SQL server with NT AuthorityAnnoymous despite I specified to use integrated security and Annoymous login is disabled in IIS.
Form / Windows authentication?

After installing the app on a 32-bit Windows Server 2008 box the users are now prompted for domain credentials every time they call the site.
