• How to get Alfresco login ticket without user password, but with impersonating user with user principal name (UPN)

  - by dok

  I'm writing a DLL that has function for getting Alfresco login ticket without using user password, using only a user principal name (UPN). I’m calling alfresco REST API service /wcservice. I use NTLM in Alfresco. I’m impersonating users using WindowsIdentity constructor as explained here http://msdn.microsoft.com/en-us/library/ms998351.aspx#paght000023_impersonatingbyusingwindowsidentity. I checked and user is properly impersonated (I checked WindowsIdentity.GetCurrent().Name property). After impersonating a user, I try to make HttpWebRequest and set its credentials with CredentialsCache.DefaultNetworkCredentials. I get the error: The remote server returned an error: (401) Unauthorized. at System.Net.HttpWebRequest.GetResponse() When I use new NetworkCredential("username", "P@ssw0rd") to set request credentials, I get Alfresco login ticket (HttpStatusCode.OK, 200). Is there any way that I can get Alfresco login ticket without user password? Here is the code that I'm using: private string GetTicket(string UPN) { WindowsIdentity identity = new WindowsIdentity(UPN); WindowsImpersonationContext context = null; try { context = identity.Impersonate(); MakeWebRequest(); } catch (Exception e) { return e.Message + Environment.NewLine + e.StackTrace; } finally { if (context != null) { context.Undo(); } } } private string MakeWebRequest() { string URI = "http://alfrescoserver/alfresco/wcservice/mg/util/login"; HttpWebRequest request = WebRequest.Create(URI) as HttpWebRequest; request.CookieContainer = new CookieContainer(1); //request.Credentials = new NetworkCredential("username", "p@ssw0rd"); // It works with this request.Credentials = CredentialCache.DefaultNetworkCredentials; // It doesn’t work with this //request.Credentials = CredentialCache.DefaultCredentials; // It doesn’t work with this either try { using (HttpWebResponse response = request.GetResponse() as HttpWebResponse) { StreamReader sr = new StreamReader(response.GetResponseStream()); return sr.ReadToEnd(); } } catch (Exception e) { return (e.Message + Environment.NewLine + e.StackTrace); } } Here are records from Alfresco stdout.log (if it helps in any way): 17:18:04,550 DEBUG [app.servlet.NTLMAuthenticationFilter] Processing request: /alfresco/wcservice/mg/util/login SID:7453F7BD4FD2E6A61AD40A31A37733A5 17:18:04,550 DEBUG [web.scripts.DeclarativeRegistry] Web Script index lookup for uri /mg/util/login took 0.526239ms 17:18:04,550 DEBUG [app.servlet.NTLMAuthenticationFilter] New NTLM auth request from 10.**.**.** (10.**.**.**:1229) 17:18:04,566 DEBUG [app.servlet.NTLMAuthenticationFilter] Processing request: /alfresco/wcservice/mg/util/login SID:7453F7BD4FD2E6A61AD40A31A37733A5 17:18:04,566 DEBUG [web.scripts.DeclarativeRegistry] Web Script index lookup for uri /mg/util/login took 0.400909ms 17:18:04,566 DEBUG [app.servlet.NTLMAuthenticationFilter] Received type1 [Type1:0xe20882b7,Domain:<NotSet>,Wks:<NotSet>] 17:18:04,566 DEBUG [app.servlet.NTLMAuthenticationFilter] Client domain null 17:18:04,675 DEBUG [app.servlet.NTLMAuthenticationFilter] Sending NTLM type2 to client - [Type2:0x80000283,Target:AlfrescoServerA,Ch:197e2631cc3f9e0a]

• ldap_bind_s returning LDAP_SUCCESS with wrong credentials

  - by rezna

  Hi guys, I have this little problem. I want to authenticate user against LDAP (Windows Active Directory), everything works OK, but the combination (good user, good password, wrong domain). LDAP* ldap = ldap_init(L"myserver", 389); ULONG ldap_version = 3; ULONG ret = LDAP_SUCCESS; ret = ldap_set_option(ldap, LDAP_OPT_PROTOCOL_VERSION, (void*)&ldap_version); ret = ldap_connect(ldap, NULL); SEC_WINNT_AUTH_IDENTITY ai; ai.Domain = (unsigned short*)BAD_DOMAIN; ai.DomainLength = wcslen(BAD_DOMAIN); ai.User = (unsigned short*)OK_USER; ai.UserLength = wcslen(OK_USER); ai.Password = (unsigned short*)OK_PASS; ai.PasswordLength = wcslen(OK_PASS); ai.Flags = SEC_WINNT_AUTH_IDENTITY_UNICODE; ret = ldap_bind_s(ldap, NULL, (PWCHAR) &ai, LDAP_AUTH_NTLM); // !!! HERE !!! ret = ldap_unbind_s(ldap); On the line marke '!!! HERE !!!' I'd expect 0x31 or any other error returned. Instead I get LDAP_SUCCESS :( Any suggestions? Thx, Milan

• Facebook Flash app security?

  - by mhdouglas

  I'm developing a Facebook app implemented in Flash, and I'd like to authenticate communication between my app and my server. In other words, I'd like to guarantee that all communication with my server is coming from my app, which has been launched from within facebook by a valid facebook user. Does the Facebook actionscript API support this type of operation? Or am I on my own?

  does anyone know if Bundler supports http auth? I'm pretty sure rubygems does (I think i read that somewhere) but I don't see anywhere in the docs where I might specify a username/pwd for a particular repo I'm trying to run my own private gem server so as not to expose sensitive code

• How can I authenticate when using the Bugzilla Perl API in a script?

  - by Allan Anderson

  Working from the Bugzilla API, I've written a quick Perl script to clone a Bugzilla Product (recreating all the Components under their new Product). The Bugzilla Perl API is quite easy to use from the command line. I could have just worked on the database directly, but I wanted a longer-term solution. Another option was the webservice, but I thought I'd try using the API directly this time. The one problem I'm running into is authenticating as my Bz admin user so I can create the new components. Looking at Bugzilla's Bugzilla.pm file, I see that they just run login() from a Bugzilla::Auth object. I'm not sure how to get the username and password in there. I suppose I could just add the script to the Bugzilla admin interface... Can any of you point me in the right direction?

• Django-allauth redirected to connections

  - by camara90100

  I'm using django-allauth to signup users with Facebook, and I'm setting the ACCOUNT_EMAIL_REQUIRED to True so when a user doesn't have email saved on his account I get redirected to the allauth/templates/socialaccount/Signup.html and when I use a test user to enter a valid email, I get redirect to "connections.html" which then asks me to choose one of the social accounts and remove it. and the form action method is set to 'connections url' so it becomes an infinite loop. anyone knows what's wrong? here's my settings SOCIALACCOUNT_PROVIDERS = \ { 'facebook': { 'SCOPE': ['email', 'publish_stream'], # 'AUTH_PARAMS': { 'auth_type': 'reauthenticate' }, 'METHOD': 'js_sdk' , 'LOCALE_FUNC': lambda request: 'en_US'}} ACCOUNT_EMAIL_REQUIRED =True ACCOUNT_ADAPTER = 'profiles.adapter.MyAccountAdapter' SOCIALACCOUNT_ADAPTER ='profiles.adapter.MySocialAccountAdapter'

• Login for webapp, needs to be available for support staff

  - by Christian W

  I know the title is a little off, but it's hard to explain the problem in a short sentence. I am the administrator of a legacy webapp that lets users create surveys and distribute them to a group of people. We have two kinds of "users". Authorized licenseholders which does all setup themselves. Clients who just want to have a survey run, but still need a user (because the webapp has "User" as the top entity in a surveyenvironment.) Sometimes users in #1 want us to do the setup for them (which we offer to do). This means that we have to login as them. This is also how we do support: we login as them and then follow them along, guiding them. Which brings me to my dilemma. Currently our security is below par. But this makes it simple for us to do support. We do want to increase our security, and one thing I have been considering is just doing the normal hashing to DB, however, we need to be able to login as a customer, and if they change their password without telling us, and the password is hashed in the db, we have no way of knowing it. So I was thinking of some kind of twoway encryption for the passwords. Either that or some kind of master password. Any suggestions? (The platform is classic ASP... I said it was legacy...)

• Why is it not good to use $_SESSION in Restful Implementations?

  - by keisimone

  Original Question: i read that for RESTful websites. it is not good to use $_SESSION. Why is it not good? how then do i properly authenticate users without looking up database all the time to check for the user's roles? I read that it is not good to use $_SESSION. http://www.recessframework.org/page/towards-restful-php-5-basic-tips I am creating a WEBSITE, not web service in PHP. and i am trying to make it more RESTful. at least in spirit. right now i am rewriting all the action to use Form tags POST and add in a hidden value called _method which would be "delete" for deleting action and "put" for updating action. however, i am not sure why it is recommended NOT to use $_SESSION. i would like to know why and what can i do to improve. To allow easy authorization checking, what i did was to after logging in the user, the username is stored in the $_SESSION. Everytime the user navigates to a page, the page would check if the username is stored inside $_SESSION and then based on the $_SESSION retrieves all the info including privileges from the database and then evaluates the authorization to access the page based on the info retrieved. Is the way I am implementing bad? not RESTful? how do i improve performance and security? Thank you.

• How can I validate/secure/authenticate a JavaScript-based POST request?

  - by Bungle

  A product I'm helping to develop will basically work like this: A Web publisher creates a new page on their site that includes a <script> from our server. When a visitor reaches that new page, that <script> gathers the text content of the page and sends it to our server via a POST request (cross-domain, using a <form> inside of an <iframe>). Our server processes the text content and returns a response (via JSONP) that includes an HTML fragment listing links to related content around the Web. This response is cached and served to subsequent visitors until we receive another POST request with text content from the same URL, at which point we regenerate a "fresh" response. These POSTs only happen when our cached TTL expires, at which point the server signifies that and prompts the <script> on the page to gather and POST the text content again. The problem is that this system seems inherently insecure. In theory, anyone could spoof the HTTP POST request (including the referer header, so we couldn't just check for that) that sends a page's content to our server. This could include any text content, which we would then use to generate the related content links for that page. The primary difficulty in making this secure is that our JavaScript is publicly visible. We can't use any kind of private key or other cryptic identifier or pattern because that won't be secret. Ideally, we need a method that somehow verifies that a POST request corresponding to a particular Web page is authentic. We can't just scrape the Web page and compare the content with what's been POSTed, since the purpose of having JavaScript submit the content is that it may be behind a login system. Any ideas? I hope I've explained the problem well enough. Thanks in advance for any suggestions.

• Login with Kohana auth module - what am I doing wrong?

  - by keithjgrant

  I'm trying to login with the following controller action, but my login attempt keeps failing (I get the 'invalid username and/or password' message). What am I doing wrong? I also tried the other method given in the examples in the auth documentation, Auth::instance()->login($user->username, $form->password);, but I get the same result. Kohana version is 2.3.4. public function login() { $auth = Auth::instance(); if ($auth->logged_in()) { url::redirect('/account/summary'); } $view = new View('login'); $view->username = ''; $view->password = ''; $post = $this->input->post(); $form = new Validation($post); $form->pre_filter('trim', 'username') ->pre_filter('trim', 'password') ->add_rules('username', 'required'); $failed = false; if (!empty($post) && $form->validate()) { $login = array( 'username' => $form->username, 'password' => $form->password, ); if (ORM::factory('user')->login($login)) { url::redirect('/accounts/summary'); } else { $view->username = $form->username; $view->message = in_array('required', $form->errors()) ? 'Username and password are required.' : 'Invalid username and/or password.'; } } $view->render(true); }

• How to transfer url parameters to repoze custom predicate checkers

  - by user281521

  I would like to create a repoze custom predicate checker that is capable to access url parameters and validate something. But I would like to use allow_only to set this permission checker in all the controller's scope. Something like: class MyController(BaseController): allow_only = All(not_anonymous(msg=l_(u'You must be logged on')), my_custom_predicate(msg=l_(u'something wrong'))) def index(self, **kw): return dict() then, my_custom_predicate should check the url paramters for every request in every MyController method, and do whatever it do. The problem is just that: how to allow my_custom_predicate to check the url parameters, using it in that way I wrote above.

• Why always fires OnFailure when return View() to Ajax Form ?

  - by Wahid Bitar

  I'm trying to make a log-in log-off with Ajax supported. I made some logic in my controller to sign the user in and then return simple partial containing welcome message and log-Off ActionLink my Action method looks like this : public ActionResult LogOn(LogOnModel model, string returnUrl) { if (ModelState.IsValid) { if (MembershipService.ValidateUser(model.UserName, model.Password)) { FormsService.SignIn(model.UserName, model.RememberMe); if (Request.IsAjaxRequest()) { //HERE IS THE PROBLEM :( return View("LogedInForm"); } else { if (!String.IsNullOrEmpty(returnUrl)) return Redirect(returnUrl); else return RedirectToAction("Index", "Home"); } } else { ModelState.AddModelError("", "The user name or password provided is incorrect."); if (Request.IsAjaxRequest()) { return Content("There were an error !"); } } } return View(model); } and I'm trying to return this simple partial : Welcome <b><%= Html.Encode(Model.UserName)%></b>! <%= Html.ActionLink("Log Off", "LogOff", "Account") %> and of-course the two partial are strongly-typed to LogOnModel. But if i returned View("PartialName") i always get OnFailure with status code 500. While if i returned Content("My Message") everything is going right. so please tell me why i always get this "StatusCode = 500" ??. where is the big mistake ??. By the way in my Site MasterPage i rendered partial to show long-on simple form this partial looks like this : <script type="text/javascript"> function ShowErrorMessage(ajaxContext) { var response = ajaxContext.get_response(); var statusCode = response.get_statusCode(); alert("Sorry, the request failed with status code " + statusCode); } function ShowSuccessMessage() { alert("Hey everything is OK!"); } </script> <div id="logedInDiv"> </div> <% using (Ajax.BeginForm("LogOn", "Account", new AjaxOptions { UpdateTargetId = "logedInDiv", InsertionMode = InsertionMode.Replace, OnSuccess = "ShowSuccessMessage", OnFailure = "ShowErrorMessage" })) { %> <%= Html.TextBoxFor(m => m.UserName)%> <%= Html.PasswordFor(m => m.Password)%> <%= Html.CheckBoxFor(m => m.RememberMe)%> <input type="submit" value="Log On" /> < <% } %>

• Rails: Accessing the username/password used for HTTP Basic Auth?

  - by Shpigford

  I'm building a basic API where user information can be retrieved after that user's login and password are correctly sent. Right now I'm using something like this: http://foo:[email protected]/api/user.xml So, what I need to do is access the user/password sent in the request (the foo and bar) but am not sure how to access that info in a Rails controller. Then I'd check those variables via a quick User.find and then set those as the username and password variables for authenticate_or_request_with_http_basic. It's possible I'm looking at this at the completely wrong way, but that's where I'm at right now. :)

• Calling https process from ASP Net

  I have an ASP NET web server application that calls another process running on the same box that creates a pdf file and returns it. The second process requires a secure connection via SSL. The second process has issued my ASP NET application with a digital certificate but I still cannot authenticate, getting a 403 error. The code is a little hard to show but here's a simplified method ... X509Certificate cert = X509Certificate.CreateFromCertFile("path\to\cert.cer"); string URL = "https://urltoservice?params=value"; HttpWebRequest req = HttpWebRequest.Create(URL) as HttpWebRequest; req.ClientCertificates.Add(cert); req.Credentials = CredentialCache.DefaultCredentials; req.PreAuthenticate = true; /// error happens here WebResponse resp = req.GetResponse(); Stream input = resp.GetResponseStream(); The error text is "The remote server returned an error: (403) Forbidden." Any pointers are welcome.

I am trying to use django.contrib.comments, I saw the table in the database like this, but how can I integrate it with user_id, user_photos, user_name, user_email....and those things with the django commenting system?

• When to Store Temporary Values in Hidden Field vs. Session vs. Database?

  - by viatropos

  I am trying to build a simple OpenID login panel similar to how Stack Overflow's works. The goal is: User clicks OpenID/Oauth provider OpenID/Oauth stuff happens, we end up with the result (already made that) Then we want to confirm that the user wants to actually create a new account (vs. associating account with another OpenID account). In StackOverflow, they keep a hidden field on a form that looks like this: <form action="/users/openidconfirm" method="post"> <p>This is an OpenID we haven't seen on Stack Overflow before:</p> <p class="openid-identifier">https://me.yahoo.com/a/some-hash</p> <p>Do you want to associate this OpenID with your Stack Overflow account?</p> <div> <input type="hidden" name="fkey" value="9792ab2zza1q2a4ac414casdfa137eafba7"> <input type="hidden" name="s" value="c1a3q133-11fa-49r0-a7bz-da19849383218"> <input type="submit" value="Associate OpenID"> <input type="button" value="Cancel" onclick="window.location.href = 'http://stackoverflow.com/users/169992/viatropos?s=c1a3q133-11fa-49r0-a7bz-da19849383218'"> </div> </form> Initial question is, what are those hashes fkey and s? Not that I really care what these specific hashes are, but what it seems like is happening is they have processed the openid response and saved it to the DB in a temporary object or something, and from there they generate these keys, because they don't look like Oauth keys to me. Main situation is: after I have processed OpenID/Oauth responses, I don't yet want to create a new user/account until the user submits the "confirm" form. Should I store the keys and tokens temporarily in a "Confirm" form like this? Or is there a better way? It seems that using a temp database object would be a lot of work to manage properly. Thanks for the help. Lance

• Update User Info with restful_authentication plugin in Rails?

  - by benoror

  Hi people, I want to give the users the ability to change their account info with restful_authentication plugin in rails. I added this two methods to my users controller: def edit @user = User.find(params[:id]) end def update @user = User.find(params[:id]) # Only update password when necessary params[:user].delete(:password) if pàrams[:user][:password].blank? respond_to do |format| if @user.update_attributes(params[:user]) flash[:notice] = 'User was successfully updated.' format.html { redirect_to(@user) } format.xml { head :ok } else format.html { render :action => "edit" } format.xml { render :xml => @user.errors, :status => :unprocessable_entity } end end end Also, I copied new.html.erb to edit.html.erb. Considering that resources are already defined in routes.rb I was expecting it to work easily, bute somehow when I click the save button it calls the create method, instead of update, using a POST http request. Inmediatly after that it autocatically log out form the session. Any ideas?
