How To Authenticate A Windows Mobile Client Calling Web Services In Web App
Mar 21, 2010I have a fairly complex business application written in ASP.NET that is deployed on a hosted server. The site uses Forms Authentication, and there are about a dozen different roles defined. Employees and customers are both users of the application.
Now I have the requirement to develop a Windows Mobile client for the application that allows a very specialized set of tasks to be performed from a device, as opposed to a browser on a laptop. The client wants to increase productivity with this measure. Only employees will use this application.
I feel that it would make sense to re-use the security infrastructure that is already in place. The client does not need offline capability.
My thought is to deploy a set of web services to a folder of the existing site that only the new role "web service" has access to, and to use Forms Authentication (from a Windows Mobile 5/.Net 3.5 client).
I did see this question and I am aware of the limitations that Forms Authentication poses. Since security is not my primary motivator (I use SSL and can restrict access by IP address), but rather using existing user accounts and roles, my decision tree is somewhat different as well.
WCF / ASMX :: Web Services: To Authenticate Sign Client Assembly?
Jul 21, 2010I have an application that exposes a number of ASP.NET web services at an internet location. For security reasons, I want to be able to authenticate clients, and reject any that are not authorised. The authorised clients in question will be ASP.NET web applications,
but I do not have guaranteed access to their IIS configuration, nor to their local certificate stores, therefore the solution must not involve any of these items.
However, authorised clients, will always make calls to the web services using wrapper methods provided by an assembly that I
do have control over. My idea is to digitally sign that assembly, and use that signature as the basis for authenticating the client.For that to work, the assembly will need to be able to construct an X509Certificate object from itself, and to attach it to the call to the web service:
X509Certificate cert = X509Certificate.CreateFromSignedFile(Assembly.GetExecutingAssembly().Location);
_webService.ClientCertificates.Add(cert);
Then the web service must be able to compare the incoming request certificate to its own signing certificate to authenticate the client:
X509Certificate requestCert = new X509Certificate(Context.Request.ClientCertificate.Certificate);
X509Certificate signingCert = X509Certificate.CreateFromSignedFile(Assembly.GetExecutingAssembly().Location);[code]...
The documentation for the method doesn't help much, other than remarking that ASN.1 DER is the only certificate format supported by the method. if I am signing the assembly incorrectly, misunderstanding the method itself etc.? Or more generally if the approach I am taking will work or is flawed?
Authenticate User Between ASP And WCF?
Feb 19, 2010We are developing a browser based intranet application. All users have active directory account, so obvious choice would be use Integrated Windows Authentication. But there will be multiple users accessing same client machine so we decided to use form based authentication (but authenticated against AD). In this scenario what is the best way to authenticate between my ASP.NET application (IIS) and WCF Services (another server IIS 7). I don't want to use asp.Net Compatibility mode or certificate. I am thinking to create another domain account to authenticate ASP.NET and WCF. I am also passing the information about the current ASP.NET user to WCF as header info. Is this the right way to do? The following code will call from ASP.NET to access and get each service method.
// Call WCF service from ASP.NET Application using a new domain account for each call.
proxy.ClientCredentials.Windows.ClientCredential.Domain = "mydomain";
ServiceReference.HelloWorldClient proxy = new ServiceReference.HelloWorldClient();
proxy.ClientCredentials.Windows.ClientCredential.UserName = "new_domain_account";
proxy.ClientCredentials.Windows.ClientCredential.Password = "password";
Is there any better way to authenticate WCF from ASP.NET?
IE8 User Can't Authenticate With Web Service?
Jun 8, 2010I have an asp.net app. It has a page that requires authentication. The authenticated user can view the page because he/she is authenticated. The page makes a jQuery Ajax call to a WCF service. The WCF service checks that the user is authenticated via HttpContext. I have a user that is using WinXP and IE8. This user can authenticate to the page, but when the Ajax call is made from the page to the wb service, the user recieves my "session not authenticated" message on the page, generated by the service and displayed on the page. When I use the same OS/browser combo, the page and service work just fine, as expected; no errors.
What option in this user's IE settings would cause this behavior?

View 4 RepliesWhere In The Web Forms Lifecycle Can Re-authenticate A User
Jan 15, 2010Here's the situation - Most of this ASP.NET Web Forms application (which uses a single master page for all pages) with Forms Authentication, has a standard session timeout, but there are some "modes" where we store an encoded cookie that links the user to their account.
I would like to manually check early on in the page lifecycle for the cookie, and if certain conditions are met, manually re-establish the user's authentication ticket/session.
Where's the best place to do this? Master page Page_Init? Global.asax BeginRequest?
Sharepoint AD User Authenticate To Another Domain?
Jun 11, 2010I have a situation where I have to autheticate SharePoint user to another website that is not part of the sharepoint domain without asking user to login again.
I have sharepoint part of domain1. I have users in domain1 that log into sharepoint using NTLM by authenticating to domain1. I don't have any control over this domain and sharepoint configuration. I am working on a ASP.net application which needs to authenticate users from domain1 without prompting users for login if they have already logged into sharepoint server.
I may be able to install a webpart on the Sharepoint if this allows me to do single sign on between sharepoint and my application.

C# - Authenticate Against A Local Windows User On Another Machine In An Application?
May 24, 2010In my ASP.NET application, I need to be able to authenticate/authorise against local Windows users/groups (ie. not Active Directory) on a different machine, as well as be able to change the passwords of said remote local Windows accounts.
Yes, I know Active Directory is built for this sort of thing, but unfortunately the higher ups have decreed it needs to be done this way (so authentication against users in a database is out as well).
I've tried using DirectoryEntry and WinNT like so:
DirectoryEntry user = new DirectoryEntry(String.Format("WinNT://{0}/{1},User",
serverName, username), username, password, AuthenticationTypes.Secure)
but this results in an exception when you try to log in more than one user:
Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again.
I've tried making sure my DirectoryEntries are used inside a using block, so they're disposed properly, but this doesn't seem to fix the issue. Plus, even if that did work it is possible that two users could hit that line of code concurrently and therefore try to create multiple connections, so it would be fragile anyway.
Is there a better way to authenticate against local Windows accounts on a remote machine, authorise against their groups, and change their passwords?

How To Authenticate An HTTP Request To Remote Server That Can Be Utilize On End User Browser

C# - FormsAuthentication.Authenticate Fails To Authenticate?
Feb 8, 2011I currently have an odd problem with ASP.Net authentication. Consider the two following lines:
MembershipCreateStatus ct = new MembershipCreateStatus();
Membership.CreateUser("admin", "mypassword", "test@gmail.com", "1", "1", true, out ct);
This does register my user in my database. I have verified this.However, when I run this immediately after:
FormsAuthentication.Authenticate("admin", "mypassword");
The authentication fails. The weird thing is I know for a fact that the user does exist in the db, and that is further confirmed if i run
MembershipUserCollection uc = Membership.FindUsersByName("admin");
and uc does hold my admin user withe all the proper info. why Authenticate would return false?
