Add Per Request - Token Based Authentication To Mvc Site
Apr 4, 2011I have an existing asp.net mvc website that uses basic forms authentication. The site has a login page that posts back to a login action, which logs the user in via FormsAuthentication.SetAuthCookie(). I am looking to add an api to the site, as an mvc2 area, where users would be authenticated based on a token passed as an http header. This area will consist of only json actions, so redirecting the user to a login page doesn't make sense. Instead, I want the users to just pass a token along with each request. That token is mapped to each user account and the user would be authenticated automatically.
I'm struggling with where to put this logic. At this point, the best choice seems to be adding the header lookup logic and authentication to the Global.asax in the Application_AuthenticateRequest method. I want to avoid needing to redirect the user after calling FormsAuthentication.SetAuthCookie(), though. I want the login action to be transparent to them. Am I approaching this the wrong way? As a side note: Requiring a username/password for api requests is not possible, as the site has a mix of users. Some joined using OpenID while the rest joined with a username/password.
Security - Securing Forms Authentication Token On Client Side?
Jul 16, 2010In my website, I am not using any authentication or authorization. I've created login page to capture the user credentials and check against database. If the user successfully authenticates, it's storing the user data in session and navigating to other pages. How thinking of implementing Forms Authentication, but my concern is how to secure the authentication token in client browser for security reasons. Does anyone have any ideas how to secure the authentication token?
View 1 RepliesSecurity :: Using AD Authentication With Form Based Authentication & AzMan
Sep 2, 2010I needed information regarding the capabilities & integration of AzMan tool with Asp.net.Currently, I got a Sharepoint 2007 website along with ASP.NET 2008 where I am using Form Based Authenication.Now, the requirement is any user within a domain registered in AD should be able to login in website through intranet.
Can I acheive this using AzMan, or I need to create two websites one with FBA for internet users and the other one for the intranet users with AD authenication. Also my intenet website is deployed and in use where usermapping and roles are already created, so using this tool what will be the impact on existing webiste.
Authentication Through A Token Pass In MVC?
Sep 15, 2010I'm working on a solution to part of my companys site that is done in 2 different languages. My part of the project is in ASP.NET, and the login portal is in a different language. We pass authentication credentials by storing login information in the database on the portal page and then sending a corresponding token to the URL in the page written in .NET. Almost all the tutorials and articles I've read about security for ASP.NET, and most languages, the message has generally been "just use the built in stuff and don't mess with it".
I have code that takes the token, goes into the database and gets the user details.. what do I do then to integrate that into the built-in security stuff for ASP.NET? I'd like to ultimately use Action Filters for authorization on my controllers.
WCF / ASMX :: SSO Authentication Token And POX Interfaces
Jul 28, 2010We have a SSO authentication service that other externally facing web pages and services use to authenticate users. A user tries to reach a service, if no cookie is found containing an authentication token, they are redirected (HTTP 302) to the SingleSignOn authentication service. The auth service does it's work, and redirects the user (HTTP 302) to the original URL with their encrypted authentication token in the URL. Great. How can I invoke this from a WCF POX service? No SOAP here, just HTTP GET/POST with XML responses.
What I'm currently doing is, in each service method implementation method, checking the headers for the cookie. If the cookie exists, verify the auth token and process the request. If the cookie doesn't exist or the auth token has expired, then respond with:
[Code]....
That works, but isn't integrated with any of the WCF features, and requires me to manually code for a whole bunch of scenarios. Is there a way I could implement this using these classes:
[Code]....
or use some other means that checks each request to the service? I've been reading pages like: How to: Create a Custom Token, but I don't see how it applies to my needs. I'm looking into this because I have some time before my project kicks off, and I'd like to implement this project correctly and learn about WCF as much as I can.
IE Not Saving Authentication Token / Cookies?
Oct 30, 2010I have an asp.net site. Its a mixture of web forms and MVC2.
I have this on 2 different servers which I get to via different urls.
On one server authentication works fine via all browsers (IE 8, FF 3.6, Chrome)
On the other IE 8 fails, it doesn't send back the cookie on the request to the page after authenticating.
Using Fiddler I have seen that both sites attempt to set the cookie, in the response from the login page.
Response Header I see from both servers
Set-Cookie: DemandLaunch=CCA4...E79C2D1; path=/; HttpOnly
Both sites are in the internet zone of IE.
I'm at a loose for what to check now.
I also have a page that sets a cookie via c# code and that cookie fails in IE as well.
The IE issue is not on a single computer either. I see this failure on 4 different computers Internet Explorer.
My urls which I should have included were:
beta.[site].com - works
beta_[company].[site].com - fails
Windows Authentication Header Token Not Being Sent?
Feb 21, 2011I'm trying to get a ASP.NET application to use windows authentication. I have disabled anonymous auth and enabled windows auth in IIS7. On my dev box (my workstation, localhost) I can use fiddler and see proper token is passed in through the header and I'm not prompted. Everything is working fine and I'm authenticated as my domain user.
However, on a remote server on our domain, with identical settings, I continually get prompted. We need it to automatically send the domain authentication for windows auth.
Does anything in IE need to be configured for this to happen for a remote machine on the same domain?
How To Get Anonymous Authentication Token For Profile Support
Jun 14, 2010So I have an asp.net Web Application (Not Web Site) that I am trying to support profiles for anonymous users. I have a form and I want anonymous users to be able to enter their name and email only once, and have that information automatically accessible on the next load for them.
In my Web.config I have anonymous ID setup like so:
<anonymousIdentification enabled="true" cookieless="AutoDetect" />
I have my profile section setup like this:
<profile defaultProvider="SqlProvider" enabled="true" inherits="QA_Web_Tools.UserProfile">
<providers>
<clear />
<add connectionStringName="QAToolsConnectionString" name="SqlProvider"
type="System.Web.Profile.SqlProfileProvider" />
</providers>
</profile>
Finally, due to my app being a Web App and not a Web Site, I am using the profiles via this custom object:
public class UserProfile : ProfileBase
{
public static UserProfile GetUserProfile(string username)
{
return Create(username) as UserProfile;
}
public static UserProfile GetUserProfile()
{
return Create(Membership.GetUser().UserName) as UserProfile;
}
[SettingsAllowAnonymous(true)]
public string FullName
{
get { return base["FullName"] as string; }
set { base["FullName"] = value; }
}
[SettingsAllowAnonymous(true)]
public string BuildEmail
{
get { return base["BuildEmail"] as string; }
set { base["BuildEvmail"] = value; }
}
}
This code is based off of this reference. The issue is that that code does not support anonymous users, or if it does I don't know how. I can't use the GetUserProfile() method with no parameters because if the user is anonymous, Membership.GetUser() is null. I could pass in the anonymous ID token into the first GetUserProfile(string username) method but I cant' find any way to get the anonymous ID token for the current user. Does anyone know how to get this information? Google doesn't seem to be returning useful results.

Security :: Finding Guideline For 'Role-based Authentication/authorization'?
Aug 26, 2010In my asp.net website in VS-2005 with SQL-Server 2005 as db, I need to implement role-based Authentication/Authorization.
I am familiar to the practises used in role-based authentication..as I have previously worked on projects that used this method. However, my project lead used to design the database. Now I have an existing website where authentication has been set to anonymous by setting 'allow users="?"' in the authentication tags in web.config.
If I use the createUserWizard control and use the Membership.creatUser(.....) method in code behind will the asp.net security tables, like users, roles, userinrole etc get created on its own?
Security :: Role Based Authorization Using Froms Authentication Fails?
Oct 5, 2010I am trying to implement a simple role based authorization using forms authentication in ASP.net. It works perfectly fine in my local system but fails when I deploy in production (shared hosting). Whenever I try to log in, rather than taking me to the default page in specified directory it throws me back to the login page. I suspect that there is some issues with the configuration but not sure where the problem is. The code is provided below:
Web.config (root):
[Code]....
Web.config (Member directory):
[Code]....
Login.aspx:
[Code]....
Global.asax:
[Code]....
Works fine in local machine but shared hosting is not taking the authenticated user to the pages inside the secured folders. What can be the issue?

Security :: Forms Based Authentication Allow Only Specific Users From Database Table?
Oct 1, 2010I have the following implementation and I'm sure there is an easy way to do what I want to do but I can't figure it out.
1. I use forms based authentication to authenticate to my site
2. I use active directory to authenticate the users
3. I use the Allow Users="xxx" tag to authorize the users limited to the list that can access my site. (e.g.. even though Mary is an AD user she can't access my site unless I put her credentials in the allow users tag in the web.config file)
All is working well but I want to move the users access list (e.g.. <allow users="john" />" from the web.config to a database table so that I can create a user maintenance page for my admins to add and delete user access. For the life of me I can't figure out how to do this and I can't seem to find an article on it either.

Security :: How To Security Token Transfer To J2EE Web Application
Mar 6, 2010Here is 2 web applications: 1 is asp.net, another is J2EE base webapplication.Both them are using same AD ( e.g. DomainTest ) as authentication source.Question here:1. User log in the asp.net application ( form based log in DomainTest, not IE prompt authencation dialog ), on the left navigation ( link to J2EE web application), just click this link, SSO to J2EE application.I think should transfer identity token from asp.net to J2EE, but don't know how, and for JSP, how to modify it to use token tranferd from asp.net ?
View 3 RepliesSecurity :: Storing A Token In Browser Or In Querystring?
Feb 17, 2010We have developed a system to allow users to access another one of our web applications by placing a token in the db and then when they redirect passing this token in the browser to the new apop and using that as an authenication method. However I am thinking that it might be better to simply place this token in the browser cookie as then the user doesnt have to physically click a link they can simply do straight to it because the token wont be in the query string anymore....
Will it add much of an overhead doing it via cookies are there any disadvantages?
Security :: Add An Expiration Token To A Existing Querystring?
Jul 2, 2010I don't know if the following is possible or not but in brief, here is what I'm trying to achieve:
1. When a user requests to view a document, they click on a link (could be other) which contains an encrypted query string containing data required to retrieve the relevant document. i.e.[URL]
2. I want to ensure that if after x minutes the user goes back to their history and select the link again or re-type the same url as above that it will not request the document and redirect them to a page letting them know that the requested document "link" is no longer valid.
I don't want to rely on cookies or sessions, so thought that maybe there would be a way to add a datetime token at the end of the existing url but this needs to be done at run-time as the url is already predefined when the link is created, so I'm not sure how can I do this?
ideally, I'd like something like this [URL] where the token would contain the date & time when the link was clicked.
Once re-requested, I would decrypt the token and validate it again the server time and if it was over the x minutes defined, it would redirect me to the "link is no longer valid" page.
WIF Security Token Service Not Staying Logged In
Aug 27, 2010I'm using the Windows Identity Foundation (WIF) Security Token Service (STS) to handle authentication for my application which is working all well and good. However I can't seem to get any long running login with the STS. From my understanding I shouldn't care about the client tokens at the application level since they can expire all they want to and it should redirect me to the STS and as long as they're still logged in on the STS it should refresh their application token. Yet it doesn't seem to want to keep them signed in.
Here's what occurs in my login.aspx on the STS
var cookie = FormsAuthentication.GetAuthCookie(userName, persistTicket);
if (persistTicket) cookie.Expires = DateTime.Now.AddDays(14);
Response.Cookies.Add(cookie);
var returnUrl = Request.QueryString["ReturnUrl"];
Response.Redirect(returnUrl ?? "default.aspx");
Which was taken almost directly from existing application using normal Forms Auth.
From my web.config
<authentication mode="Forms">
<forms loginUrl="Login.aspx" protection="All" timeout="2880"
name=".STS" path="/" requireSSL="false" slidingExpiration="true"
defaultUrl="default.aspx" cookieless="UseDeviceProfile"
enableCrossAppRedirects="false" />
</authentication>
Looking at the cookie after I sign in I can see the expires time on the cookie is set for 14 days in the future and that the cookie is NOT a session cookie. When I'm required to log back into the STS I can see that my original cookie is still there. Is there some kind of time stamp functionality that the STS embeds into the cookie that is invalidating my cookie even though as far as I know it should still be valid?
Security :: Token Login Don't Keep Session With Two Applications?
Jun 15, 2010I've two application ASP.NET (once is Mojo Portal). I can navigate from one to other using an URL token id.
To this way, by token, I create a new session and save the relative auth cookie.
But, sometimes, the asp web application don't keep the session and put me down. When this happen I can't login until the session cookies is not deleted.
Both the two application are behind an reverse proxy.
Cookies - Windows Identity Foundation - How To Get New Security Token
Feb 1, 2010I'm writing an ASP.net application that uses Windows Identity Foundation. My ASP.net application uses claims-based authentication with passive redirection to a security token service. This means that when a user accesses the application, they are automatically redirected to the Security Token Service where they receive a security token which identifies them to the application.
In ASP.net, security tokens are stored as cookies.
I want to have something the user can click on in my application that will delete the cookie and redirect them to the Security Token Service to get a new token. In short, make it easy to log out and log in as another user. I try to delete the token-containing cookie in code, but it persists somehow.
How do I remove the token so that the user can log in again and get a new token?
