  • ASP.Net and FaceBook Wall integration

    - by Jit
    Hi, I am new to FaceBook API. I like to send messages when I want from my aspx webpage. I used the different examples and used FaceBook API 3.1. I am getting error as "service temporarily unavailable". I have assigned AppKey, Secret Key and session key. My sample code is below. using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using Facebook; using Facebook.Web; using Facebook.Rest; using Facebook.Session; using Facebook.Utility; using Facebook.BindingHelper; using Facebook.Schema; using Facebook.Web.FbmlControls; using Facebook.Session.DesktopPopup; namespace FaceBookApp { public partial class _Default : System.Web.UI.Page { private const string ApplicationKey = "MY_APP_KEY"; private const string SecretKey = "MY_SECRET_KEY"; private Api fbAPI; private ConnectSession _connectSession; // private List<EventUser> _eventUsers; protected void Page_Load(object sender, EventArgs e) { } protected void Button1_Click(object sender, EventArgs e) { _connectSession = new ConnectSession(ApplicationKey, SecretKey); _connectSession.SessionKey = "MY_SESSION_KEY"; if (!_connectSession.IsConnected()) { // Not authenticated, proceed as usual. //lblStatus.Text = "Please sign-in with Facebook."; } else { // Authenticated, create API instance fbAPI = new Api(_connectSession); string response = fbAPI.Stream.Publish("publish steven on facebook."); } } } } The error message is confusing. It must be a very simple solution. I don't know what I am missing. Pls help. Here is the facebook exception. {"Service temporarily unavailable"}

  • CascadingDropDownList not working with anonymous access

    - by Alessandro
    Hi everyone, I use a CascadingDropDownList of the AJAXControlToolkit in a ASP.NET MCMS 2002 web application. The CascadingDropDownList works as expected until "Anonymous access" and "Integrated Windows Authentication" flags are both checked (and this is the situation in the production environment) in the Directory Security settings on the website under IIS. The error I get is: 500 Internal Server Error No web service found at: If I uncheck the anonymous access or the windows authentication everything is ok. Any suggestions?

  • practical security ramifications of increasing WCF clock skew to more than an hour

    - by Andrew Patterson
    I have written a WCF service that returns 'semi-private' data concerning peoples name, addresses and phone numbers. By semi-private, I mean that there is a username and password to access the data, and the data is meant to be secured in transit. However, IMHO noone is going to expend any energy trying to obtain the data, as it is mostly available in the public phone book anyway etc. At some level, the security is a bit of security 'theatre' to tick some boxes imposed on us by government entities. The client end of the service is an application which is given out to registered 'users' to run within their own IT setups. We have no control over the IT of the users - and in fact they often tell us to 'go jump' if we put too many requirements on their systems. One problem we have been encountering is numerous users that have system clocks that are not accurate. This can either be caused by a genuine slow/fast clocks, or more than likely a timezone or daylight savings zone error (putting their machine an hour off the 'real' time). A feature of the WCF bindings we are using is that they rely on the notion of time to detect replay attacks etc. <wsHttpBinding> <binding name="normalWsBinding" maxBufferPoolSize="524288" maxReceivedMessageSize="655360"> <reliableSession enabled="false" /> <security mode="Message"> <message clientCredentialType="UserName" negotiateServiceCredential="false" algorithmSuite="Default" establishSecurityContext="false" /> </security> </binding> </wsHttpBinding> The inaccurate client clocks cause security exceptions to be thrown and unhappy users. Other than suggesting users correct their clocks, we know that we can increase the clock skew of the security bindings. http://www.danrigsby.com/blog/index.php/2008/08/26/changing-the-default-clock-skew-in-wcf/ My question is, what are the real practical security ramifications of increasing the skew to say 2 hours? If an attacker can perform some sort of replay attack, why would a clock skew window of 5 minutes be necessarily safer than 2 hours? I presume performing any attack with security mode of 'message' requires more than just capturing some data at a proxy and sending the data back in again to 'replay' the call? In a situation like mine where data is only 'read' by the users, are there indeed any security ramifications at all to allowing 'replay' attacks?

  • How to cancel a long running WCF requests from silverlight 3

    - by Kim
    I have a silverlight 3 application that makes several long running requests to a WCF service. While these calls are in progress, any other later WCF calls are queued by silverlight 3 because it will only do two requests at the same time, thus making the application suck :( How can I cancel the long running blocking requests?

  • Retrieve EF4 POCOs using WCF REST services starter kit

    - by muruge
    I am using WCF REST service (GET method) to retrieve my EF4 POCOs. The service seem to work just fine. When I query the uri in my browser I get the results as expected. In my client application I am trying to use WCF REST Starter Kit's HTTPExtension method - ReadAsDataContract() to convert the result back into my POCO. This works fine when the POCO's navigation property is a single object of related POCO. The problem is when the navigation property is a collection of related POCOs. The ReadAsDataContract() method throws an exception with message "Object reference not set to an instance of an object." Below are my POCOs. [DataContract(Namespace = "", Name = "Trip")] public class Trip { [DataMember(Order = 1)] public virtual int TripID { get; set; } [DataMember(Order = 2)] public virtual int RegionID { get; set; } [DataMember(Order = 3)] public virtual System.DateTime BookingDate { get; set; } [DataMember(Order = 4)] public virtual Region Region { // removed for brevity } } [DataContract(Namespace = "", Name = "Region")] public class Region { [DataMember(Order = 1)] public virtual int RegionID { get; set; } [DataMember(Order = 2)] public virtual string RegionCode { get; set; } [DataMember(Order = 3)] public virtual FixupCollection<Trip> Trips { // removed for brevity } } [CollectionDataContract(Namespace = "", Name = "{0}s", ItemName = "{0}")] [Serializable] public class FixupCollection<T> : ObservableCollection<T> { protected override void ClearItems() { new List<T>(this).ForEach(t => Remove(t)); } protected override void InsertItem(int index, T item) { if (!this.Contains(item)) { base.InsertItem(index, item); } } } And this is how I am trying retrieve a Region POCO. static void GetRegion() { string uri = "http://localhost:8080/TripService/Regions?id=1"; HttpClient client = new HttpClient(uri); using (HttpResponseMessage response = client.Get(uri)) { Region region; response.EnsureStatusIsSuccessful(); try { region = response.Content.ReadAsDataContract<Region>(); // this line throws exception because Region returns a collection of related trips Console.WriteLine(region.RegionName); } catch (Exception ex) { Console.WriteLine(ex.Message); } } } Would appreciate any pointers.

  • NameClaimType in ClaimsIdentity from SAML

    - by object88
    I am attempting to understand the world of WIF in context of a WCF Data Service / REST / OData server. I have a hacked up version of SelfSTS that is running inside a unit test project. When the unit tests start, it kicks off a WCF service, which generates my SAML token. This is the SAML token being generated: <saml:Assertion MajorVersion="1" MinorVersion="1" ... > <saml:Conditions>...</saml:Conditions> <saml:AttributeStatement> <saml:Subject> <saml:NameIdentifier Format="EMAIL">4bd406bf-0cf0-4dc4-8e49-57336a479ad2</saml:NameIdentifier> <saml:SubjectConfirmation>...</saml:SubjectConfirmation> </saml:Subject> <saml:Attribute AttributeName="emailaddress" AttributeNamespace="http://schemas.xmlsoap.org/ws/2005/05/identity/claims"> <saml:AttributeValue>[email protected]</saml:AttributeValue> </saml:Attribute> <saml:Attribute AttributeName="name" AttributeNamespace="http://schemas.xmlsoap.org/ws/2005/05/identity/claims"> <saml:AttributeValue>bob</saml:AttributeValue> </saml:Attribute> </saml:AttributeStatement> <ds:Signature>...</ds:Signature> </saml:Assertion> (I know the Format of my NameIdentifier isn't really EMAIL, this is something I haven't gotten to cleaning up yet.) Inside my actual server, I put some code borrowed from Pablo Cabraro / Cibrax. This code seems to run A-OK, although I confess that I don't understand what's happening. I note that later in my code, when I need to check my identity, Thread.CurrentPrincipal.Identity is an instance of Microsoft.IdentityModel.Claims.ClaimsIdentity, which has a claim for all the attributes, plus a nameidentifier claim with the value in my NameIdentifier element in saml:Subject. It also has a property NameClaimType, which points to "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name". It would make more sense if NameClaimType mapped to nameidentifier, wouldn't it? How do I make that happen? Or am I expecting the wrong thing of the name claim? Thanks!
