• SharePoint form-based authentication with custom database

  - by Clodin

  Hi, I have SharePoint site and I want to use form-based authentication, not Windows how it is by default. For this I read that I have to modify the web.config from Central Administration and web.config from my site with the membership and roleManager tags configured properly. But if I use this: <membership> <providers> <add name="MyProvider" type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" .../> </providers> </membership> System.Web.Security.SqlMembershipProvider requires a database generated with ASP.NET SQL Server Setup Wizard (aspnet_regsql.exe), and this is my problem! I want to use another database with cunstom table 'Users' from where to take the username and password for authentication. How can I do this? Thank you in advance

• Attaching catalog with SQL Authentication credentials attaches it as Read-Only

  - by Nissim

  Hello, As part of our product's installation process, a database is attached to the server. We use EXEC sp_attach_db in order to attach it to MSSQL. The problem occures when we try to attach it with "SQL Authentication" connection string - the database is attached to the server as read-only, thus preventing any write access from being performed This is driving us nuts... it's working just fine with Windows Authentication, and the only difference is the connection string... I tried googling for it but no mention for such a scenario is found. Any ideas anyone? It's important to mention that the MDF/LDF physical files are not set with "ReadOnly" attribute, so this is not the problem.

• ASP.NET Windows authentication with wrong identity over VPN

  - by Dilyan Dimitrov

  I have ASP.NET application with windows authentication. When I browse it from home over VPN (Cisco VPN Client) as a username in the windows identity I get "\" not the credentials from the AD of the server (the same that I am using to connect to the VPN) even though I fill them in the prompt for localhost authentication from the browser. This only happens with Firefox. In the IE and Chrome after the prompt I get 401.1 Unauthorized page from IIS. How to make IIS to use the right credentials or the problem is somewhere else? Any ideas?

• Prompts for windows authentication when viewing a page in Web site

  - by Sri Kumar

  Hello All, When i try to view a PARTICULAR page in my web site, it prompts for user name and password. Irrespective of providing proper user name/password and clicking OK or directly clicking Cancel button, the page is getting loaded properly. I am not sure why the authentication screen appears!!! It happens only for that particular page. Initially I thought it could be with file permission but copy pasted another page (which works fine) and renaming it doesn't solve the problem. Thoughts pl. EDIT I copied the source from the browser for that particular page and saved it as HTML. When i try to open the HTML file, it prompts for authentication.

• How to eliminate authentication on my MVC app that is called from asp.net forms app

  - by Mark Kadlec

  Curious what recommendations anyone has. I have an existing asp.net forms application that does a Forms Authentication and has identity impersonate turned on. The application has a link to a questionnaire that I would like to develop separately in an asp.net MVC application, but I don't want the users to click on the link and be prompted for a username and password, I would like them to be able seamless start filling out the questionnaire. Is there a way to somehow transfer authentication from one .net app to another? I would like to be able to pass stuff like UserRole. What's the best way to do this?

• Forms Authentication Across Applications Stopped Working

  - by colleski

  Hi, I have a .net 1.1 ASP application (domain.com) which has a .net 2 virtual directory (domain.com/v2) beneath it, both applications run within their own app pool on the same machine running IIS 6. The web.config files for both apps are setup for Forms Authentication as described here - http://msdn.microsoft.com/en-us/library/eb0zx8fc(v=VS.80).aspx. Users would be directed to the domain.com/v2/login.aspx page which would authenticate for both applications, this configuration has been working fine for the last few years until installing one of the recent Windows 2003 security updates today. Now after authenticating under /v2 users keep getting redirected back to domain.com/v2/Login.aspx as domain.com doesnt see them as authenticated anymore. Any ideas as to which security update would have caused this and if its possible to rollback? I've looked at a few suggestions on this (e.g. Cross app on subdomain form authentication not working) and other sites but no luck so far Any help would be appreciated. Thanks

• Re-authentication required for registered-path links (to ASP.NET site) coming to IE from PowerPoint

  - by Daniel Halsey

  We're using URL routing based on Phil Haack's example, with config modifications based on MSDN Library article #CC668202, to provide "shareable" links for a ASP.NET forms site, and have run into a strange issue: For users attempting to open links from PowerPoint presentations, and who have IE set as their default browser, using one of these links forces (forms-based) re-authentication, even in the same browser instance with a live session. Info: We know the session is still alive. (Page returns information for the currently logged-in user; confirmed via debug watches) This doesn't happen with other browsers (FF, Chrome) or with other programs (Notepad++) as the URL source. We do not have a default path set, as this caused issues with root path handling at initial login. This primarily happens with PowerPoint, but will also happen in Word and OCS. On some machines, even after changing the default browser, Office apps will continue to use IE for these links, forcing this error. (A potential registry fix for this failed, but even if it had worked, we can't control default browser choice for our users.) We can't figure out if this is an Office oddity or is being caused by our decision to use app-level URL routing (rather than IIS rewriting). Has anyone else encountered this and found a solution?

• Set Context User Principal for Customized Authentication in SignalR

  - by Shaun

  Originally posted on: http://geekswithblogs.net/shaunxu/archive/2014/05/27/set-context-user-principal-for-customized-authentication-in-signalr.aspxCurrently I'm working on a single page application project which is built on AngularJS and ASP.NET WebAPI. When I need to implement some features that needs real-time communication and push notifications from server side I decided to use SignalR. SignalR is a project currently developed by Microsoft to build web-based, read-time communication application. You can find it here. With a lot of introductions and guides it's not a difficult task to use SignalR with ASP.NET WebAPI and AngularJS. I followed this and this even though it's based on SignalR 1. But when I tried to implement the authentication for my SignalR I was struggled 2 days and finally I got a solution by myself. This might not be the best one but it actually solved all my problem.   In many articles it's said that you don't need to worry about the authentication of SignalR since it uses the web application authentication. For example if your web application utilizes form authentication, SignalR will use the user principal your web application authentication module resolved, check if the principal exist and authenticated. But in my solution my ASP.NET WebAPI, which is hosting SignalR as well, utilizes OAuth Bearer authentication. So when the SignalR connection was established the context user principal was empty. So I need to authentication and pass the principal by myself.   Firstly I need to create a class which delivered from "AuthorizeAttribute", that will takes the responsible for authenticate when SignalR connection established and any method was invoked. 1: public class QueryStringBearerAuthorizeAttribute : AuthorizeAttribute 2: { 3: public override bool AuthorizeHubConnection(HubDescriptor hubDescriptor, IRequest request) 4: { 5: } 6:  7: public override bool AuthorizeHubMethodInvocation(IHubIncomingInvokerContext hubIncomingInvokerContext, bool appliesToMethod) 8: { 9: } 10: } The method "AuthorizeHubConnection" will be invoked when any SignalR connection was established. And here I'm going to retrieve the Bearer token from query string, try to decrypt and recover the login user's claims. 1: public override bool AuthorizeHubConnection(HubDescriptor hubDescriptor, IRequest request) 2: { 3: var dataProtectionProvider = new DpapiDataProtectionProvider(); 4: var secureDataFormat = new TicketDataFormat(dataProtectionProvider.Create()); 5: // authenticate by using bearer token in query string 6: var token = request.QueryString.Get(WebApiConfig.AuthenticationType); 7: var ticket = secureDataFormat.Unprotect(token); 8: if (ticket != null && ticket.Identity != null && ticket.Identity.IsAuthenticated) 9: { 10: // set the authenticated user principal into environment so that it can be used in the future 11: request.Environment["server.User"] = new ClaimsPrincipal(ticket.Identity); 12: return true; 13: } 14: else 15: { 16: return false; 17: } 18: } In the code above I created "TicketDataFormat" instance, which must be same as the one I used to generate the Bearer token when user logged in. Then I retrieve the token from request query string and unprotect it. If I got a valid ticket with identity and it's authenticated this means it's a valid token. Then I pass the user principal into request's environment property which can be used in nearly future. Since my website was built in AngularJS so the SignalR client was in pure JavaScript, and it's not support to set customized HTTP headers in SignalR JavaScript client, I have to pass the Bearer token through request query string. This is not a restriction of SignalR, but a restriction of WebSocket. For security reason WebSocket doesn't allow client to set customized HTTP headers from browser. Next, I need to implement the authentication logic in method "AuthorizeHubMethodInvocation" which will be invoked when any SignalR method was invoked. 1: public override bool AuthorizeHubMethodInvocation(IHubIncomingInvokerContext hubIncomingInvokerContext, bool appliesToMethod) 2: { 3: var connectionId = hubIncomingInvokerContext.Hub.Context.ConnectionId; 4: // check the authenticated user principal from environment 5: var environment = hubIncomingInvokerContext.Hub.Context.Request.Environment; 6: var principal = environment["server.User"] as ClaimsPrincipal; 7: if (principal != null && principal.Identity != null && principal.Identity.IsAuthenticated) 8: { 9: // create a new HubCallerContext instance with the principal generated from token 10: // and replace the current context so that in hubs we can retrieve current user identity 11: hubIncomingInvokerContext.Hub.Context = new HubCallerContext(new ServerRequest(environment), connectionId); 12: return true; 13: } 14: else 15: { 16: return false; 17: } 18: } Since I had passed the user principal into request environment in previous method, I can simply check if it exists and valid. If so, what I need is to pass the principal into context so that SignalR hub can use. Since the "User" property is all read-only in "hubIncomingInvokerContext", I have to create a new "ServerRequest" instance with principal assigned, and set to "hubIncomingInvokerContext.Hub.Context". After that, we can retrieve the principal in my Hubs through "Context.User" as below. 1: public class DefaultHub : Hub 2: { 3: public object Initialize(string host, string service, JObject payload) 4: { 5: var connectionId = Context.ConnectionId; 6: ... ... 7: var domain = string.Empty; 8: var identity = Context.User.Identity as ClaimsIdentity; 9: if (identity != null) 10: { 11: var claim = identity.FindFirst("Domain"); 12: if (claim != null) 13: { 14: domain = claim.Value; 15: } 16: } 17: ... ... 18: } 19: } Finally I just need to add my "QueryStringBearerAuthorizeAttribute" into the SignalR pipeline. 1: app.Map("/signalr", map => 2: { 3: // Setup the CORS middleware to run before SignalR. 4: // By default this will allow all origins. You can 5: // configure the set of origins and/or http verbs by 6: // providing a cors options with a different policy. 7: map.UseCors(CorsOptions.AllowAll); 8: var hubConfiguration = new HubConfiguration 9: { 10: // You can enable JSONP by uncommenting line below. 11: // JSONP requests are insecure but some older browsers (and some 12: // versions of IE) require JSONP to work cross domain 13: // EnableJSONP = true 14: EnableJavaScriptProxies = false 15: }; 16: // Require authentication for all hubs 17: var authorizer = new QueryStringBearerAuthorizeAttribute(); 18: var module = new AuthorizeModule(authorizer, authorizer); 19: GlobalHost.HubPipeline.AddModule(module); 20: // Run the SignalR pipeline. We're not using MapSignalR 21: // since this branch already runs under the "/signalr" path. 22: map.RunSignalR(hubConfiguration); 23: }); On the client side should pass the Bearer token through query string before I started the connection as below. 1: self.connection = $.hubConnection(signalrEndpoint); 2: self.proxy = self.connection.createHubProxy(hubName); 3: self.proxy.on(notifyEventName, function (event, payload) { 4: options.handler(event, payload); 5: }); 6: // add the authentication token to query string 7: // we cannot use http headers since web socket protocol doesn't support 8: self.connection.qs = { Bearer: AuthService.getToken() }; 9: // connection to hub 10: self.connection.start(); Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

• "Unknown user name or bad password" when I launch ADUC

  - by Chris

  When I open up Active Directory Users and Computers from my workstation, I receive an error: Naming information cannot be located because: Logon failure: unknown user name or bad password. Contact your system administrator to verify that your domain is properly configured and is currently online. If I log in to my workstation as somebody else, it works. If I log into a different workstation using my account, it works. All the workstations in question are running Windows Vista (32 and 64 bit) or Windows Server 2008. The domain controller in question is running Windows Small Business Server 2008. Everything else (that I tried) in the Remote Server Administration Tools runs just fine. Any thoughts? Edit: I just tried reinstalling RSAT. No such luck.

• HTTP Basic Authentication with HTTPService Objects in Adobe Flex/AIR

  - by Bob Somers

  I'm trying to request a HTTP resource that requires basic authorization headers from within an Adobe AIR application. I've tried manually adding the headers to the request, as well as using the setRemoteCredentials() method to set them, to no avail. Here's the code: <mx:Script> <![CDATA[ import mx.rpc.events.ResultEvent; import mx.rpc.events.FaultEvent; private function authAndSend(service:HTTPService):void { service.setRemoteCredentials('someusername', 'somepassword'); service.send(); } private function resultHandler(event:ResultEvent):void { apiResult.text = event.result.toString(); } private function resultFailed(event:FaultEvent):void { apiResult.text = event.fault.toString(); } ]]> </mx:Script> <mx:HTTPService id="apiService" url="https://mywebservice.com/someFileThatRequiresBasicAuth.xml" resultFormat="text" result="resultHandler(event)" fault="resultFailed(event)" /> <mx:Button id="apiButton" label="Test API Command" click="authAndSend(apiService)" /> <mx:TextArea id="apiResult" /> However, a standard basic auth dialog box still pops up prompting the user for their username and password. I have a feeling I'm not doing this the right way, but all the info I could find (Flex docs, blogs, Google, etc.) either hasn't worked or was too vague to help. Any black magic, oh Flex gurus? Thanks. EDIT: Changing setRemoteCredentials() to setCredentials() yields the following ActionScript error: [MessagingError message='Authentication not supported on DirectHTTPChannel (no proxy).'] EDIT: Problem solved, after some attention from Adobe. See the posts below for a full explanation. This code will work for HTTP Authentication headers of arbitrary length. import mx.utils.Base64Encoder; private function authAndSend(service:HTTPService):void { var encoder:Base64Encoder = new Base64Encoder(); encoder.insertNewLines = false; // see below for why you need to do this encoder.encode("someusername:somepassword"); service.headers = {Authorization:"Basic " + encoder.toString()}; service.send(); }

• Django users and authentication from external source

  - by Boldewyn

  I have a Django app that gets it's data completely from an external source (queried via HTTP). That is, I don't have the option for a local database. Session data is stored in the cache (on my development server I use a SQLite database, so that is no error source). I'm using bleeding edge Django 1.1svn. Enter the problem: I want to use Django's own authentication system for the users. It seems quite simple to write my own Authentication Backend, but always just under the condition that you have a local database where to save the users. Without database my main problem is persistence. I tried it with the following (assume that datasource.get() is a function that returns some kind of dict): class ModelBackend (object): """Login backend.""" def authenticate (self, username=None, password=None): """Check, if a given user/password combination is valid""" data = datasource.get ('login', username, password) if data and data['ok']: return MyUser (username=username) else: raise TypeError return None def get_user (self, username): """get data about a specific user""" try: data = datasource.get ('userdata', username) if data and data['ok']: return data.user except: pass return None class MyUser (User): """Django user who isn't saved in DB""" def save (self): return None But the intentionally missing save() method on MyUser seems to break the session storage of a login. How should MyUser look like without a local database?

• cakephp: Custom Authentication Object authenticate not called

  - by Kristoffer Darj

  The method authenticate in a Custom Authentication Object is never called. Is this a glicth or am I missing something? I don't get anything in the log, I'm just redirected to users/login (or the one I specified) CakeVersion: 2.4.1 <?php //My custom Auth Class //Path: app/Controller/Component/Auth/HashAuthenticate.php App::uses('BaseAuthenticate', 'Controller/Component/Auth'); class HashAuthenticate extends BaseAuthenticate { public function authenticate(CakeRequest $request, CakeResponse $response) { //Seems to not be called CakeLog::write('authenticate'); debug($this); die('gaah'); } } If I add the method getUser() (or unauthenticated() ), those gets called however so at least I know that cake finds the class and so on. It just skips the authenticate-method. The AppController looks like this class AppController extends Controller { public $helpers = array('Html', 'Form', 'Session'); public $components = array('Auth' => array( 'authenticate' => array('Hash'), 'authorize' => array('Controller'), ) ); } I found a similar question here: CakePHP 2.x custom "Authentication adapter &quot;LdapAuthorize&quot; was not found but there the issue was typos.

• Overriding windows authentication for a .NET application

  - by JoshReedSchramm

  I have a .NET application where the homepage (default.aspx) should be accessible by anyone. There is also a reporting page (reporting.aspx) that I want to secure via windows authentication and only allow access to a particular set of AD groups. Right now the way my web.config is setup it is securing the reporting page but on the home page it prompts the user for login credentials. If they hit esc they can continue to the page though so it isnt actually securing it. I need to prevent it from prompting the user. How do i need to setup my config. Here is what i have now - <system.web> <authentication mode="Windows" /> <identity impersonate="true" /> <authorization> <allow roles="BUILTIN\Administrators, DomainName\Manager" /> <deny users="?" /> </authorization> ...MORE STUFF... </system.web> <location path="default.aspx"> <system.web> <identity impersonate="false" /> <authorization> <allow users="*"/> </authorization> </system.web> </location>

• SECURITY Flaws in this design for User authentication.

  - by Shao

  SECURITY Flaws in this design for User authentication. From: http://wiki.pylonshq.com/display/pylonscookbook/Simple+Homegrown+Authentication Note: a. Project follows the MVC pattern. b. Only a user with a valid username and password is allowed submit something. Design: a. Have a base controller from which all controllers are derived from. b. Before any of the actions in the derived controllers are called the system calls a before action in the base controller. c. In each controller user hardcodes the actions that need to be verified in an array. d. The before action first looks in the array that has the actions that are protected and sees if a user is logged in or not by peaking into the session. If a user is present then user is allowed to submit otherwise user is redirected to login page. What do you think?

• ASP.NET Authentication Cookie timout and IIS 7 setting

  - by David Laplante

  Hello, I have an ASP.NET website for which i've set the authetication timeout to 60 days so that my users don't have to log in each time they come back if they checked the "remember me" option. Basic ASP.NET login mechanism... It's working fine on my developpement server as well as on the visual studio built-in web server. I can close the browser, wait around 30-40 minutes and browse back to the site and be automatically logged in. However, I've not moved the site to a hosting provider and it seems that whatever I do to my Web.config file, the cookie expires after around 30 minutes (hard to tell the exact amount of time). I have asked the provider's help support and they basically told me: "Web.config file is to configure your website. Please do not change it if you don't know what you are doing" Frustrating answer indeed... To be sure, I checked everywhere on the net for exceptions, fine prints, in the basic asp.net authentication but found none. I have access to IIS remote management for my site (IIS 7) but don't really know where to look. Can there be something in the IIS setting that is overriding my web.config authentication setting? What should I do... Thanks for you help!

• Authentication Error when accessing Sharepoint list via web service

  - by Joe

  I wrote a windows service a few months ago that would ping a Sharepoint list using _vti_bin/lists.asmx function GetListItemChanges. It was working fine until a few weeks ago when my company upgraded our Sharepoint instance to SP1. Now whenever my service attempts to access Sharepoint I receive an 401.1 authentication error: Error: You are not authorized to view this page You do not have permission to view this directory or page using the credentials that you supplied. Please try the following: Contact the Web site administrator if you believe you should be able to view this directory or page. HTTP Error 401.1 - Unauthorized: Access is denied due to invalid credentials. Internet Information Services (IIS) I have checked and my privileges on the site have not changed. here is the code In which I call the list: Lists listsService = new Lists(); listsService.Credentials = new NetworkCredential("UserName", "Password", "domain"); Result = listsService.GetListItemChanges("List name", null, dTime.ToString(), null); It has also been brought to my attention that basic authentication may have been disabled on our farm. I don't believe I'm using that but I may be mistaken.

• Authentication using cookie key with asynchronous callback

  - by greg

  I need to write authentication function with asynchronous callback from remote Auth API. Simple authentication with login is working well, but authorization with cookie key, does not work. It should checks if in cookies present key "lp_login", fetch API url like async and execute on_response function. The code almost works, but I see two problems. First, in on_response function I need to setup secure cookie for authorized user on every page. In code user_id returns correct ID, but line: self.set_secure_cookie("user", user_id) does't work. Why it can be? And second problem. During async fetch API url, user's page has loaded before on_response setup cookie with key "user" and the page will has an unauthorized section with link to login or sign on. It will be confusing for users. To solve it, I can stop loading page for user who trying to load first page of site. Is it possible to do and how? Maybe the problem has more correct way to solve it? class BaseHandler(tornado.web.RequestHandler): @tornado.web.asynchronous def get_current_user(self): user_id = self.get_secure_cookie("user") user_cookie = self.get_cookie("lp_login") if user_id: self.set_secure_cookie("user", user_id) return Author.objects.get(id=int(user_id)) elif user_cookie: url = urlparse("http://%s" % self.request.host) domain = url.netloc.split(":")[0] try: username, hashed_password = urllib.unquote(user_cookie).rsplit(',',1) except ValueError: # check against malicious clients return None else: url = "http://%s%s%s/%s/" % (domain, "/api/user/username/", username, hashed_password) http = tornado.httpclient.AsyncHTTPClient() http.fetch(url, callback=self.async_callback(self.on_response)) else: return None def on_response(self, response): answer = tornado.escape.json_decode(response.body) username = answer['username'] if answer["has_valid_credentials"]: author = Author.objects.get(email=answer["email"]) user_id = str(author.id) print user_id # It returns needed id self.set_secure_cookie("user", user_id) # but session can's setup

• Forms Authentication & Virtual Directory

  - by benclaytonfranklin

  Hi, We're having trouble getting Forms Authentication to work with a virtual directory in IIS. We have a main site, and then a microsite setup within a virtual directory. This mircosite has its own admin system within an "Admin" folder, which has authentication on it but currently it is not kicking in and the admin section is browsable by anyone. The web.config with the admin folder has the following: <?xml version="1.0"?> <configuration> <appSettings/> <connectionStrings/> <system.web> <authorization> <deny users="?"/> </authorization> <customErrors mode="RemoteOnly" defaultRedirect="~/Admin/Error.aspx"/> </system.web> </configuration> Could anyone give me any clues as to why this might not be working? Cheers!

• Implement user authentication against remote DB with a Web Service

  - by Juan González

  I'm just starting reasearch about the best way to implement user authentication within my soon-to-be app. This is what I have so far: A desktop (Windows) application on a remote server. That application is accessed locally with a browser (it has a web console and MS SQL Server to store everything). The application is used with local credendials stored in the DB. This is what I'd like to accompllish: Provide access to some information on that SQL Server DB from my app. That access of course must be granted once a user has id himself with valid credentials. This is what I know so far: How to create my PHP web service and query info from a DB using JSON. How to work with AFNetworking libraries to retrieve information. How to display that info on the app. What I don't know is which could be the best method to implement user authentication from iOS. Should I send username and password? Should I send some hash? Is there a way to secure the handshake? I'd for sure appreciate any advise, tip, or recommendation you have from previous experience. I don't want to just implement it but instead I want to do it as good as possible.

• Http authentication with apache httpcomponents

  - by matdan

  Hi, I am trying to develop a java http client with apache httpcomponents 4.0.1. This client calls the page "https://myHost/myPage". This page is protected on the server by a JNDIRealm with a login form authentication, so when I try to get https://myHost/myPage I get a login page. I tried to bypass it unsuccessfully with the following code : //I set my proxy HttpHost proxy = new HttpHost("myProxyHost", myProxyPort); //I add supported schemes SchemeRegistry supportedSchemes = new SchemeRegistry(); supportedSchemes.register(new Scheme("http", PlainSocketFactory .getSocketFactory(), 80)); supportedSchemes.register(new Scheme("https", SSLSocketFactory .getSocketFactory(), 443)); // prepare parameters HttpParams params = new BasicHttpParams(); HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1); HttpProtocolParams.setContentCharset(params, "UTF-8"); HttpProtocolParams.setUseExpectContinue(params, true); ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, supportedSchemes); DefaultHttpClient httpclient = new DefaultHttpClient(ccm, params); httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy); //I add my authentication information httpclient.getCredentialsProvider().setCredentials( new AuthScope("myHost/myPage", 443), new UsernamePasswordCredentials("username", "password")); HttpHost host = new HttpHost("myHost", 443, "https"); HttpGet req = new HttpGet("/myPage"); //show the page ResponseHandler<String> responseHandler = new BasicResponseHandler(); String rsp = httpClient.execute(host, req, responseHandler); System.out.println(rsp); When I run this code, I always get the login page, not myPage. How can I apply my credential parameters to avoid this login form? Any help would be fantastic

• C# & SQL Server Authentication

  - by Peter

  Hello, I'm currently developing a C# app with an SQL Server DB back-end. I'm approaching the point of deployment and hitting a problem. The applicaiton will be deployed within an active directory network. As far as SQL authentication goes, I understand that I have 2 options - Windows Authenticaiton or Server Authenticaiton. If I use Server Authentication, I'm concerned that the username and password for the account will be stored in plain text in the app.config file, and therefore leave the database vulnerable. Using Windows Authenticaiton will avoid this issue, however it would mean giving every member of staff within our organisation read/write access to the database in order to run the app correctly. Whilst this is ok, it also means that they can easily connect to the database themselves via other means and directly alter the data outside of the app. I'm guessing there is someting really obvious I'm missing here, but I've been googling all evening to no avail. Any advice/guidance would be much appreciated! Peter Addition - my project is Windows Form based not ASP.NET - is encrypting the app.config file still the right answer? If it is, does anyone have any examples that are not ASP.NET based?

• Protecting routes with authentication in an AngularJS app

  - by Chris White

  Some of my AngularJS routes are to pages which require the user to be authenticated with my API. In those cases, I'd like the user to be redirected to the login page so they can authenticate. For example, if a guest accesses /account/settings, they should be redirected to the login form. From brainstorming I came up with listening for the $locationChangeStart event and if it's a location which requires authentication then redirect the user to the login form. I can do that simple enough in my applications run() event: .run(['$rootScope', function($rootScope) { $rootScope.$on('$locationChangeStart', function(event) { // Decide if this location required an authenticated user and redirect appropriately }); }]); The next step is keeping a list of all my applications routes that require authentication, so I tried adding them as parameters to my $routeProvider: $routeProvider.when('/account/settings', {templateUrl: '/partials/account/settings.html', controller: 'AccountSettingCtrl', requiresAuthentication: true}); But I don't see any way to get the requiresAuthentication key from within the $locationChangeStart event. Am I overthinking this? I tried to find a way for Angular to do this natively but couldn't find anything.

• In IIS6, how to provide authenticated access to static files on remote server

  - by frankadelic

  We have a library of ZIP files that we would like to make available for download at an ASP.NET site. The files are sitting on a NAS device that is accessible from out web farm. Here is our initial strategy: Map an IIS virtual directory to the shared drive at path /zipfiles Users can download the zip files when given the URL However, if users share links to the files, anyone can download them. We would instead like to make use of the ASP.NET forms authentication in our site to validate users' requests before initiating the file transfer. A few problems: A request for a zip file is handled by IIS, not ASP.NET. So it is not subject to forms authentication. In addition, we don't want ASP.NET to handle the request, because it uses up an ASP.NET thread and is not scalable for download of large files. So, configuring the asp.net dll to handle *.zip requests is not an option. Any ideas on this? One idea we've tossed around is this: Initial request for download will be for an ashx handler. This handler will, after authentication, generate a download token which is saved to a database. Then, the user is redirected to the file with token appended in QueryString (e.g. /files/xyz.zip?token=123456789). An ISAPI plugin will be used to check the token. Also, the token will expire after x amount of time. Any thoughts on this? I have not implemented an ISAPI plugin so I'm not sure if this will even work. I would like to avoid custom coding since security is an issue and I'd prefer to use a time-tested solution.

• What's the easiest way to create an HTTP proxy which adds basic authentication to requests?

  - by joshdoe

  I am trying to use a service provided by a server which requires basic HTTP authentication, however the application I am using does not support authentication. What I'd like to do is create a proxy that will enable my auth-less application to connect via the proxy (which will add the authentication information) to the server requiring authentication. I'm sure this can be done, however I'm overwhelmed with the number of proxies out there and couldn't find an answer how to do this. Basically it seems all I want to do is have a proxy serve this URL: http://username:password@remoteserver/path as this URL: http://proxyserver/path I can run it on Linux, but a plus if I can run it Windows as well. Open source or at least free is a must. A big plus is if it's fairly straightforward to setup.
