  • How can I enable anonymous access to a Samba share under ADS security mode?

    - by hemp
    I'm trying to enable anonymous access to a single service in my Samba config. Authorized user access is working perfectly, but when I attempt a no-password connection, I get this message: Anonymous login successful Domain=[...] OS=[Unix] Server=[Samba 3.3.8-0.51.el5] tree connect failed: NT_STATUS_LOGON_FAILURE The message log shows this error: ... smbd[21262]: [2010/05/24 21:26:39, 0] smbd/service.c:make_connection_snum(1004) ... smbd[21262]: Can't become connected user! The smb.conf is configured thusly: [global] security = ads obey pam restrictions = Yes winbind enum users = Yes winbind enum groups = Yes winbind use default domain = true valid users = "@domain admins", "@domain users" guest account = nobody map to guest = Bad User [evilshare] path = /evil/share guest ok = yes read only = No browseable = No Given that I have 'map to guest = Bad User' and 'guest ok' specified, I don't understand why it is trying to "become connected user". Should it not be trying to "become guest user"?

  • Using SQL Developer to Debug your Anonymous PL/SQL Blocks

    - by JeffS
    Everyone knows that SQL Developer has a PL/SQL debugger – check! Everyone also knows that it’s only setup for debugging standalone PL/SQL objects like Functions, Procedures, and Packages, right? – NO! SQL Developer can also debug your Stored Java Procedures AND it can debug your standalone PLSQL blocks. These bits of PLSQL which do not live in the database are also known as ‘Anonymous Blocks.’ Anonymous PL/SQL blocks can be submitted to interactive tools such as SQL*Plus and Enterprise Manager, or embedded in an Oracle Precompiler or OCI program. At run time, the program sends these blocks to the Oracle database, where they are compiled and executed. Here’s an example of something you might want help debugging: Declare x number := 0; Begin Dbms_Output.Put(Sysdate || ' ' || Systimestamp); For Stuff In 1..100 Loop Dbms_Output.Put_Line('Stuff is equal to ' || Stuff || '.'); x := Stuff; End Loop; End; / With the power of remote debugging and unshared worksheets, we are going to be able to debug this ANON block! The trick – we need to create a dummy stored procedure and call it in our ANON block. Then we’re going to create an unshared worksheet and execute the script from there while the SQL Developer session is listening for remote debug connections. We step through the dummy procedure, and this takes OUT to our calling ANON block. Then we can use watches, breakpoints, and all that fancy debugger stuff! First things first, create this dummy procedure - create or replace procedure do_nothing is begin null; end; Then mouse-right-click on your Connection and select ‘Remote Debug.’ For an in-depth post on how to use the remote debugger, check out Barry’s excellent post on the subject. Open an unshared worksheet using Ctrl+Shift+N. This gives us a dedicated connection for our worksheet and any scripts or commands executed in it. Paste in your ANON block you want to debug. Add in a call to the dummy procedure above to the first line of your BEGIN block like so Begin do_nothing(); ... Then we need to setup the machine for remote debug for the session we have listening – basically we connect to SQL Developer. You can do that via a Environment Variable, or you can just add this line to your script - CALL DBMS_DEBUG_JDWP.CONNECT_TCP( 'localhost', '4000' ); Where ‘localhost’ is the machine where SQL Developer is running and ’4000′ is the port you started the debug listener on. Ok, with that all set, now just RUN the script. Once the PL/SQL call is made, the debugger will be invoked. You’ll end up in the DO_NOTHING() object. Debugging an ANON block from SQL Developer is possible! If you step out to the ANON block, we’ll end up in the script that’s used to call the procedure – which is the script you want to debug. The Anonymous Block is opened in a new SQL Dev page You can now step through the block, using watches and breakpoints as expected. I’m guessing your scripts are going to be a bit more complicated than mine, but this serves as a decent example to get you started. Here’s a screenshot of a watch and breakpoint defined in the anon block being debugged: Breakpoints, watches, and callstacks - oh my! For giggles, I created a breakpoint with a passcount of 90 for the FOR LOOP to see if it works. And of course it does You Might Also EnjoyUsing Pass Counts to Turbo Charge Your PL/SQL BreakpointsSQL Developer Tip: Viewing REFCURSOR OutputThe PL/SQL Debugger Strikes Back: Episode VDebugging PL/SQL with SQL Developer: Episode IVHow to find dependent objects in your PL/SQL Programs using SQL Developer

  • C++ and C#, "Casting" Functions to Delegates, What's the scoop?

    - by Jacob G
    In C# 2.0, I can do the following: public class MyClass { delegate void MyDelegate(int myParam); public MyClass(OtherObject obj) { //THIS IS THE IMPORTANT PART obj.SomeCollection.Add((MyDelegate)MyFunction); } private void MyFunction(int myParam); { //... } } Trying to implement the same thing in C++, it appears I have to do: MyDelegate del = gcnew MyDelegate(this, MyFunction); obj-SomeCollection-Add(del); Obviously I can create a new instance of the delegate in C# as well instead of what's going on up there. Is there some kind of magic going on in the C# world that doesn't exist in C++ that allows that cast to work? Some kind of magic anonymous delegate? Thanks.

  • How to get aspnet_Users.UserId for an anonymous user in ASP.NET membership ?

    - by Simon_Weaver
    I am trying to get the aspnet membership UserId field from an anonymous user. I have enabled anonymous identification in web.config : <anonymousIdentification enabled="true" /> I have also created a profile: <profile> <providers> <clear /> <add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="ApplicationServices" applicationName="/" /> </providers> <properties> <add name="Email" type="System.String" allowAnonymous="true"/> <add name="SomethingElse" type="System.Int32" allowAnonymous="true"/> </properties> </profile> I see data in my aspnetdb\aspnet_Users table for anonymous users that have had profile information set. Userid PropertyNames PropertyValuesString 36139818-4245-45dd-99cb-2a721d43f9c5 Email:S:0:17: [email protected] I just need to find how to get the 'Userid' value. It is not possible to use : Membership.Provider.GetUser(Request.AnonymousID, false); The Request.AnonymousID is a different GUID and not equal to 36139818-4245-45dd-99cb-2a721d43f9c5. Is there any way to get this Userid. I want to associate it with incomplete activity for an anonymous user. Using the primary key of aspnet_Users is preferable to having to create my own GUID (which I could do and store in the profile). This is basically a dupe of this question but the question was never actually answered.

  • Adding More Than 2 Delegates in iPhone App

    - by golfromeo
    This is a simple question that can be answered fast by someone who's more familiar with Objective-C than I am- how can one add more than 2 delegates to a Class? To clarify, I'm used to putting delegates in classes like this: @interface ViewController : UIViewController <UIWebViewDelegate> { ... When I try to put two delegates: @interface ViewController : UIViewController <UIWebViewDelegate> <UITextFieldDelegate> { ... ...the app gives many errors, none of which help with the situation. Is there a separator that I need to put between the delegates, or is it possible at all to have more than two? Thanks for any help in advance.

  • How to extract delegates from ViewController class?

    - by adranle
    Hi I have the problem that my view controller class has too many delegates and starts to get big. I want to write the delegates in separate classes to keep the view controller class small. For delegates that are programmatically created (like UIAlertViewDelegate) I could do it easily. The problem is in the delegates assigned in Interface Builder. How can I tell the IB to assign, for example, another class as the UITableViewDelegate or UITableViewDataSource? Or how to choose another IBAction method for a Touch UP inside Event on a button? One solution would be to delete the connections from IB and write them programmatically at ViewDidLoad, but since I have a lot of ViewControllers, this would take a long time. any other ideas?

  • Anonymous user permission issue in SharePoint Server

    - by George2
    Hello everyone, I am using SharePoint Server 2007 x64 and Windows Server 2008 x64. I have setup a site with template publishing portal. I have grant anonymous access to all the site. My question is, if I create a new page, how to grant permission to anonymous user to access (read permission) the page? I got this confusion because, for the permission setting of a page, a permission is set according to a user name (e.g. read permission for user "foo" of a page). Since anonymous user does not have a related "user name", how could I grant read permission to anonymous user? BTW: I use Windows Forms authentication and Windows NTLM authentication for my sites. Thanks in advance, George

  • "Sent on behalf" not appearing when delegates sending mails

    - by New Steve
    Ringo is a delegate of Paul's mailbox in Exchange, but when Ringo sends mail from Paul's mailbox, the recipient sees "Paul" in the sender field, rather than "Paul Sent On Behalf Of Ringo" Paul has set "Editor" permissions for Ringo to his mailbox, and Ringo has been granted "Send on behalf of" permissions in Exchange. Ringo did at one time have "Send As" permissions for Paul's mailbox in Exchange, but this has since been removed. This is also the case for all other delegates to Paul's mailbox. How do I make it so that emails sent by Paul's delegates show the "Sent On Behalf Of" information in the Sender field? Using Exchange Server 2007 and Microsoft Office Outlook 2007

  • Anonymous file sharing without login window, from Windows 7 server to XP clients

    - by Niten
    I'm trying to provide machines on a small LAN with read-only, anonymous access to files shared from a Windows 7 workstation (let's call it WIN7SVR). In particular, I don't want clients to have to deal with a login window when they navigate to, e.g., \\WIN7SVR in Windows Explorer, but we do not have a domain and synchronizing accounts between the server and clients would be intractable. There are both Windows 7 and Windows XP clients that need access to these shares. I got this working for Windows 7 clients by just enabling the Guest account on WIN7SVR and setting appropriate share permissions. Other Windows 7 machines automatically try logging in as Guest, it seems, so their users don't have to deal with the login window. The problem is with the XP clients--they can access the server if the user enters "Guest" in the login window, but I don't want users to have to do that. So from what I gather, in my limited understanding of Windows file sharing, this boils down to granting null sessions access to file shares on WIN7SVR. But I've had no success so far on that front. I've tried all the following in the local group policy editor on the Windows 7 server: Set Network access: Let Everyone permissions apply to anonymous users to Enabled Set Network access: Restrict anonymous access to Named Pipes and Shares to Disabled Added the names of corresponding shares to Network access: Shares that can be accessed anonymously Added "ANONYMOUS LOGON" to Access this computer from the network under User Rights Assignment Any advice would be highly appreciated... I'm mostly a Unix guy, so I feel somewhat out of my league with Windows file sharing. I do understand that any sort of anonymous access to file shares isn't generally ideal from a security standpoint, but it's the most practical solution for us in this case, and access to our network is well enough controlled that share-level security isn't a concern.

  • anonymous access to ftpd

    - by gcb
    I need FTP on my local LAN so my scanner can send me scans. I am on Debian sid. I installed ftpd and created the user anonymous. I removed anonymous from /etc/ftpusers When I try to login as anonymous it says: login failed. I can't seem to find any log file. I'm using FTP server (Version 6.4/OpenBSD/Linux-ftpd-0.17) update:I needed that so my printer had one place to store my scanned documents on the LAN. solved that buying a dedicated USB pen drive (thankfully I bought a printer one with plenty of options) but in the past this was a very simple task. Install ftpd, specify the directory for anonymous access, and be done with it. now every ftp daemon has several layers of security and chroot in it's core... this is just crazy when all you need a place for a printer to dump files in a secured network.

  • Is it possible to pass a structure of delegates from managed to native?

    - by Veiva
    I am writing a wrapper for the game programming library "Allegro" and its less stable 4.9 branch. Now, I have done good insofar, except for when it comes to wrapping a structure of function pointers. Basically, I can't change the original code, despite having access to it, because that would require me to fork it in some manner. I need to know how I can somehow pass a structure of delegates from managed to native without causing an AccessViolationException that has occurred so far. Now, for the code. Here is the Allegro definition of the structure: typedef struct ALLEGRO_FILE_INTERFACE { AL_METHOD(ALLEGRO_FILE*, fi_fopen, (const char *path, const char *mode)); AL_METHOD(void, fi_fclose, (ALLEGRO_FILE *handle)); AL_METHOD(size_t, fi_fread, (ALLEGRO_FILE *f, void *ptr, size_t size)); AL_METHOD(size_t, fi_fwrite, (ALLEGRO_FILE *f, const void *ptr, size_t size)); AL_METHOD(bool, fi_fflush, (ALLEGRO_FILE *f)); AL_METHOD(int64_t, fi_ftell, (ALLEGRO_FILE *f)); AL_METHOD(bool, fi_fseek, (ALLEGRO_FILE *f, int64_t offset, int whence)); AL_METHOD(bool, fi_feof, (ALLEGRO_FILE *f)); AL_METHOD(bool, fi_ferror, (ALLEGRO_FILE *f)); AL_METHOD(int, fi_fungetc, (ALLEGRO_FILE *f, int c)); AL_METHOD(off_t, fi_fsize, (ALLEGRO_FILE *f)); } ALLEGRO_FILE_INTERFACE; My simple attempt at wrapping it: public delegate IntPtr AllegroInternalOpenFileDelegate(string path, string mode); public delegate void AllegroInternalCloseFileDelegate(IntPtr file); public delegate int AllegroInternalReadFileDelegate(IntPtr file, IntPtr data, int size); public delegate int AllegroInternalWriteFileDelegate(IntPtr file, IntPtr data, int size); public delegate bool AllegroInternalFlushFileDelegate(IntPtr file); public delegate long AllegroInternalTellFileDelegate(IntPtr file); public delegate bool AllegroInternalSeekFileDelegate(IntPtr file, long offset, int where); public delegate bool AllegroInternalIsEndOfFileDelegate(IntPtr file); public delegate bool AllegroInternalIsErrorFileDelegate(IntPtr file); public delegate int AllegroInternalUngetCharFileDelegate(IntPtr file, int c); public delegate long AllegroInternalFileSizeDelegate(IntPtr file); [StructLayout(LayoutKind.Sequential, Pack = 0)] public struct AllegroInternalFileInterface { [MarshalAs(UnmanagedType.FunctionPtr)] public AllegroInternalOpenFileDelegate fi_fopen; [MarshalAs(UnmanagedType.FunctionPtr)] public AllegroInternalCloseFileDelegate fi_fclose; [MarshalAs(UnmanagedType.FunctionPtr)] public AllegroInternalReadFileDelegate fi_fread; [MarshalAs(UnmanagedType.FunctionPtr)] public AllegroInternalWriteFileDelegate fi_fwrite; [MarshalAs(UnmanagedType.FunctionPtr)] public AllegroInternalFlushFileDelegate fi_fflush; [MarshalAs(UnmanagedType.FunctionPtr)] public AllegroInternalTellFileDelegate fi_ftell; [MarshalAs(UnmanagedType.FunctionPtr)] public AllegroInternalSeekFileDelegate fi_fseek; [MarshalAs(UnmanagedType.FunctionPtr)] public AllegroInternalIsEndOfFileDelegate fi_feof; [MarshalAs(UnmanagedType.FunctionPtr)] public AllegroInternalIsErrorFileDelegate fi_ferror; [MarshalAs(UnmanagedType.FunctionPtr)] public AllegroInternalUngetCharFileDelegate fi_fungetc; [MarshalAs(UnmanagedType.FunctionPtr)] public AllegroInternalFileSizeDelegate fi_fsize; } I have a simple auxiliary wrapper that turns an ALLEGRO_FILE_INTERFACE into an ALLEGRO_FILE, like so: #define ALLEGRO_NO_MAGIC_MAIN #include <allegro5/allegro5.h> #include <stdlib.h> #include <string.h> #include <assert.h> __declspec(dllexport) ALLEGRO_FILE * al_aux_create_file(ALLEGRO_FILE_INTERFACE * fi) { ALLEGRO_FILE * file; assert(fi && "`fi' null"); file = (ALLEGRO_FILE *)malloc(sizeof(ALLEGRO_FILE)); if (!file) return NULL; file->vtable = (ALLEGRO_FILE_INTERFACE *)malloc(sizeof(ALLEGRO_FILE_INTERFACE)); if (!(file->vtable)) { free(file); return NULL; } memcpy(file->vtable, fi, sizeof(ALLEGRO_FILE_INTERFACE)); return file; } __declspec(dllexport) void al_aux_destroy_file(ALLEGRO_FILE * f) { assert(f && "`f' null"); assert(f->vtable && "`f->vtable' null"); free(f->vtable); free(f); } Lastly, I have a class that accepts a Stream and provides the proper methods to interact with the stream. Just to make sure, here it is: /// <summary> /// A semi-opaque data type that allows one to load fonts, etc from a stream. /// </summary> public class AllegroFile : AllegroResource, IDisposable { AllegroInternalFileInterface fileInterface; Stream fileStream; /// <summary> /// Gets the file interface. /// </summary> internal AllegroInternalFileInterface FileInterface { get { return fileInterface; } } /// <summary> /// Constructs an Allegro file from the stream provided. /// </summary> /// <param name="stream">The stream to use.</param> public AllegroFile(Stream stream) { fileStream = stream; fileInterface = new AllegroInternalFileInterface(); fileInterface.fi_fopen = Open; fileInterface.fi_fclose = Close; fileInterface.fi_fread = Read; fileInterface.fi_fwrite = Write; fileInterface.fi_fflush = Flush; fileInterface.fi_ftell = GetPosition; fileInterface.fi_fseek = Seek; fileInterface.fi_feof = GetIsEndOfFile; fileInterface.fi_ferror = GetIsError; fileInterface.fi_fungetc = UngetCharacter; fileInterface.fi_fsize = GetLength; Resource = AllegroFunctions.al_aux_create_file(ref fileInterface); if (!IsValid) throw new AllegroException("Unable to create file"); } /// <summary> /// Disposes of all resources. /// </summary> ~AllegroFile() { Dispose(); } /// <summary> /// Disposes of all resources used. /// </summary> public void Dispose() { if (IsValid) { Resource = IntPtr.Zero; // Should call AllegroFunctions.al_aux_destroy_file fileStream.Dispose(); } } IntPtr Open(string path, string mode) { return IntPtr.Zero; } void Close(IntPtr file) { fileStream.Close(); } int Read(IntPtr file, IntPtr data, int size) { byte[] d = new byte[size]; int read = fileStream.Read(d, 0, size); Marshal.Copy(d, 0, data, size); return read; } int Write(IntPtr file, IntPtr data, int size) { byte[] d = new byte[size]; Marshal.Copy(data, d, 0, size); fileStream.Write(d, 0, size); return size; } bool Flush(IntPtr file) { fileStream.Flush(); return true; } long GetPosition(IntPtr file) { return fileStream.Position; } bool Seek(IntPtr file, long offset, int whence) { SeekOrigin origin = SeekOrigin.Begin; if (whence == 1) origin = SeekOrigin.Current; else if (whence == 2) origin = SeekOrigin.End; fileStream.Seek(offset, origin); return true; } bool GetIsEndOfFile(IntPtr file) { return fileStream.Position == fileStream.Length; } bool GetIsError(IntPtr file) { return false; } int UngetCharacter(IntPtr file, int character) { return -1; } long GetLength(IntPtr file) { return fileStream.Length; } } Now, when I do something like this: AllegroFile file = new AllegroFile(new FileStream("Test.bmp", FileMode.Create, FileAccess.ReadWrite)); bitmap.SaveToFile(file, ".bmp"); ...I get an AccessViolationException. I think I understand why (the garbage collector can relocate structs and classes whenever), but I'd think that the method stub that is created by the framework would take this into consideration and route the calls to the valid classes. However, it seems obviously so that I'm wrong. So basically, is there any way I can successfully wrap that structure? (And I'm sorry for all the code! Hope it's not too much...)

  • Drupal node access for anonymous users

    - by MrDresden
    I've never used Drupal before so this may be something that can easily be remedied, and that would be awesome. My problem is that a block, containing node information can't be viewed by anonymous users (unregisterd/not logged in), gives a "You are not authorized to access this content." message, but shows up for logged in users. The nodes that the block contains are events, so the block shows events for the next week. I've checked the users access settings but can't find anything that could possibly remedy this. I'm using drupal core 6.26, Event 6.x-2.x-dev, Event views 6.x-2.4 If anyone has any information, or solutions, I'd greatly appreciate it.

  • Anonymous comments not saved in Drupal

    - by Marco
    For some reason I can no longer post a comment as an Anonymous user in my Drupal installation. I haven't tried in a while, so I'm not quite sure when this functionality was broken. I have Services installed, and I can post anonymous comments using comment.save. I have altered the Input Formats if that could break something. I have enabled both post comments and access comments on the anonymous user. The comments does not show up in the database. In fact, the native Drupal function comment_save isn't called when I try to comment as Anonymous (I check this by adding print_r($edit);die(); at the top of the comment_save function in comment.module. Also I read something that not having a User with the UID 0 would break the Anonymous commenting, this user exists (obviously, since commenting through Services works) I have tried out the AntiSpam module, and posted a comment as Anonymous that would get caught(and did) in the spamfilter, but this module is now disabled. I'm really running out of ideas here, does anyone have any other suggestions on what to do? In the meanwhile I'm going to attempt to backtrack the code to figure out why comment_save() isn't being called. Edit: Anonymous users also don't have to submit email and such to post, if that matters in any way.

  • Integration Patterns with Azure Service Bus Relay, Part 3: Anonymous partial-trust consumer

    - by Elton Stoneman
    This is the third in the IPASBR series, see also: Integration Patterns with Azure Service Bus Relay, Part 1: Exposing the on-premise service Integration Patterns with Azure Service Bus Relay, Part 2: Anonymous full-trust .NET consumer As the patterns get further from the simple .NET full-trust consumer, all that changes is the communication protocol and the authentication mechanism. In Part 3 the scenario is that we still have a secure .NET environment consuming our service, so we can store shared keys securely, but the runtime environment is locked down so we can't use Microsoft.ServiceBus to get the nice WCF relay bindings. To support this we will expose a RESTful endpoint through the Azure Service Bus, and require the consumer to send a security token with each HTTP service request. Pattern applicability This is a good fit for scenarios where: the runtime environment is secure enough to keep shared secrets the consumer can execute custom code, including building HTTP requests with custom headers the consumer cannot use the Azure SDK assemblies the service may need to know who is consuming it the service does not need to know who the end-user is Note there isn't actually a .NET requirement here. By exposing the service in a REST endpoint, anything that can talk HTTP can be a consumer. We'll authenticate through ACS which also gives us REST endpoints, so the service is still accessed securely. Our real-world example would be a hosted cloud app, where we we have enough room in the app's customisation to keep the shared secret somewhere safe and to hook in some HTTP calls. We will be flowing an identity through to the on-premise service now, but it will be the service identity given to the consuming app - the end user's identity isn't flown through yet. In this post, we’ll consume the service from Part 1 in ASP.NET using the WebHttpRelayBinding. The code for Part 3 (+ Part 1) is on GitHub here: IPASBR Part 3. Authenticating and authorizing with ACS We'll follow the previous examples and add a new service identity for the namespace in ACS, so we can separate permissions for different consumers (see walkthrough in Part 1). I've named the identity partialTrustConsumer. We’ll be authenticating against ACS with an explicit HTTP call, so we need a password credential rather than a symmetric key – for a nice secure option, generate a symmetric key, copy to the clipboard, then change type to password and paste in the key: We then need to do the same as in Part 2 , add a rule to map the incoming identity claim to an outgoing authorization claim that allows the identity to send messages to Service Bus: Issuer: Access Control Service Input claim type: http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier Input claim value: partialTrustConsumer Output claim type: net.windows.servicebus.action Output claim value: Send As with Part 2, this sets up a service identity which can send messages into Service Bus, but cannot register itself as a listener, or manage the namespace. RESTfully exposing the on-premise service through Azure Service Bus Relay The part 3 sample code is ready to go, just put your Azure details into Solution Items\AzureConnectionDetails.xml and “Run Custom Tool” on the .tt files.  But to do it yourself is very simple. We already have a WebGet attribute in the service for locally making REST calls, so we are just going to add a new endpoint which uses the WebHttpRelayBinding to relay that service through Azure. It's as easy as adding this endpoint to Web.config for the service:         <endpoint address="https://sixeyed-ipasbr.servicebus.windows.net/rest"                   binding="webHttpRelayBinding"                    contract="Sixeyed.Ipasbr.Services.IFormatService"                   behaviorConfiguration="SharedSecret">         </endpoint> - and adding the webHttp attribute in your endpoint behavior:           <behavior name="SharedSecret">             <webHttp/>             <transportClientEndpointBehavior credentialType="SharedSecret">               <clientCredentials>                 <sharedSecret issuerName="serviceProvider"                               issuerSecret="gl0xaVmlebKKJUAnpripKhr8YnLf9Neaf6LR53N8uGs="/>               </clientCredentials>             </transportClientEndpointBehavior>           </behavior> Where's my WSDL? The metadata story for REST is a bit less automated. In our local webHttp endpoint we've enabled WCF's built-in help, so if you navigate to: http://localhost/Sixeyed.Ipasbr.Services/FormatService.svc/rest/help - you'll see the uri format for making a GET request to the service. The format is the same over Azure, so this is where you'll be connecting: https://[your-namespace].servicebus.windows.net/rest/reverse?string=abc123 Build the service with the new endpoint, open that in a browser and you'll get an XML version of an HTTP status code - a 401 with an error message stating that you haven’t provided an authorization header: <?xml version="1.0"?><Error><Code>401</Code><Detail>MissingToken: The request contains no authorization header..TrackingId:4cb53408-646b-4163-87b9-bc2b20cdfb75_5,TimeStamp:10/3/2012 8:34:07 PM</Detail></Error> By default, the setup of your Service Bus endpoint as a relying party in ACS expects a Simple Web Token to be presented with each service request, and in the browser we're not passing one, so we can't access the service. Note that this request doesn't get anywhere near your on-premise service, Service Bus only relays requests once they've got the necessary approval from ACS. Why didn't the consumer need to get ACS authorization in Part 2? It did, but it was all done behind the scenes in the NetTcpRelayBinding. By specifying our Shared Secret credentials in the consumer, the service call is preceded by a check on ACS to see that the identity provided is a) valid, and b) allowed access to our Service Bus endpoint. By making manual HTTP requests, we need to take care of that ACS check ourselves now. We do that with a simple WebClient call to the ACS endpoint of our service; passing the shared secret credentials, we will get back an SWT: var values = new System.Collections.Specialized.NameValueCollection(); values.Add("wrap_name", "partialTrustConsumer"); //service identity name values.Add("wrap_password", "suCei7AzdXY9toVH+S47C4TVyXO/UUFzu0zZiSCp64Y="); //service identity password values.Add("wrap_scope", "http://sixeyed-ipasbr.servicebus.windows.net/"); //this is the realm of the RP in ACS var acsClient = new WebClient(); var responseBytes = acsClient.UploadValues("https://sixeyed-ipasbr-sb.accesscontrol.windows.net/WRAPv0.9/", "POST", values); rawToken = System.Text.Encoding.UTF8.GetString(responseBytes); With a little manipulation, we then attach the SWT to subsequent REST calls in the authorization header; the token contains the Send claim returned from ACS, so we will be authorized to send messages into Service Bus. Running the sample Navigate to http://localhost:2028/Sixeyed.Ipasbr.WebHttpClient/Default.cshtml, enter a string and hit Go! - your string will be reversed by your on-premise service, routed through Azure: Using shared secret client credentials in this way means ACS is the identity provider for your service, and the claim which allows Send access to Service Bus is consumed by Service Bus. None of the authentication details make it through to your service, so your service is not aware who the consumer is (MSDN calls this "anonymous authentication").

  • Tuples vs. Anonymous Types vs. Expando object. (in regards to LINQ queries)

    - by punkouter
    I am a beginner who finally started understanding anonymous types. (see old post http://stackoverflow.com/questions/3010147/what-is-the-return-type-for-a-anonymous-linq-query-select-what-is-the-best-way-t) So in LINQ queries you form the type of return value you want within the linq query right? It seems the way to do this is anonymous type right? Can someone explain to me if and when I could use a Tuple/Expando object instead? They all seem very simliar?
