Security :: How To Do Mixed Mode Authentication

Jan 13, 2011

I have a question about mixed mode authentication. I've been doing some research into this, but I haven't found the answer yet, so I figured I'd just ask:

I have an internal application that requires login. Right now it's using forms-based authentication. We'd like to make it so that, if you're internal and authenticated against Active Directory, you don't need to login to the application. However, if you're coming in from the outside (or don't have an AD account), it would then require them to login via the forms-based Login.aspx page.

From my research, it seems that the only way to do this is to enable forms based auth as the default membership provider, then on the back-end do a check at Page_Load to pull their login name, match it against the .NET membership and then authenticate them automatically - am I wrong on this?

The documents I've found all seem to point to the user having to login anyway, just the login being stored in AD - instead of having the user just login once to their machine in the morning and using that to verify them and their roles in subsequent applications.

Security :: Authentication Mode On Webconfig?

Oct 19, 2010

I have an ASP.net website running with the authentication mode on the web.config file is Windows. The webpages at the root do not need to have login & password form.

Now I created a subfolder called 'reports' and would like to implement a few web pages with the login & password authentication form.

Question, do I need to create another web.config file in the 'reports' folder and update the authentication mode="Forms"?

Security :: Mixed Mode Authentication With IIS7?

Jan 20, 2011

I'm having a tough time implementing mixed-mode authentication (windows & forms based) for my application using IIS 7. Doing it in IIS6 is easy, but the process doesn't translate to 7/7.5 - and my research has led to me to conflicting answers, none of which.

I have redirect page called WindowsLogin.aspx, and a forms-based one called Login.aspx. I'm having difficulty enabling Windows authentication for just WindowsLogin.aspx.

VS 2010 / IIS7 - Mixed Mode Authentication

Sep 14, 2011

I am trying to implement single sign on for users within our domain and if the are not then they get re-directed to the login screen to use forms authentication.

I have followed this tutorial below

however I get two issues firstly if I go to my forms authentication page no css or images now display and if i try to login i get an error.

If I go to the login page which should recognise me from the AD I get 401 - Unauthorized: Access is denied due to invalid credentials. You do not have permission to view this directory or page using the credentials that you supplied.

WCF - Compatibility Mode And Custom Authentication Using Membership Providers

Oct 26, 2010

To begin with I work on the large application, that has a WinForms client and server. Server in our case is the set of WCF services. There is one service that is responsible for authentication of users. The logic of authentication is custom and complex and authentication service uses different membership providers.

We want to protect the access to server services for non-authenticated users. The users must firstly authenticate and than use other services (users in this case are the other systems, services, WinForms client, etc.). On this basis, we decided to use the ASP.NET Url/File Authorization feature.

So, I set on the ASP.NET compatibility mode, allowed cookie in all binding configurations, added AspNetCompatibilityRequirements attribute to our services and added the followingconfigurations to config:

<authentication mode="Forms">
<forms cookieless="UseCookies">
<credentials passwordFormat="Clear" />
<deny users="?" />
<location path="AuthenticationService.svc">
<allow users="*" />

In the authenticate method of our authentication service I add the following code:
public AuthenticationResult AuthenticateUser(string username, string password)
AuthenticationResult result = new AuthenticationResult();
result = Authenticate(username, password);
if (result.IsAuthenticated)
FormsAuthentication.SetAuthCookie(username, true);
return result;

Next, I wrote the following code:

var authClient = new AuthenticationServiceClient();
var result = authClient.AuthenticateUser("user", "password");
var otherClient = new OtherServiceClient();
var temp = otherClient.DoSomething();

But after authentication I can't access to OtherServiceClient...

So, how can I share the call context between the WCF services calls? Could anybody provide some useful articles about this question?

Security :: Mixed Mode Authentication Fails In Multiple IIS Websites

Jan 26, 2010

I created a mixed mode authentication mechanism based on a few of the articles that I have read on this topic. It's similar to something like this: [URL]

Basically, there are two web applications. One accepts the Windows Auth and one accepts Forms Auth. The Windows Auth then creates a forms auth ticket and passes control to the Forms auth application. This solution works fine when both applications are housed within the same IIS web site.

Now, order to control the security of this solution we set up multiple IIS web sites on the same machine. Web Site 1 serves external traffic (forms auth) and Web Site 2 serves internal traffic (windows auth).

So the design is that an internal user can hit the site using Windows auth via a internal name (myserver) while the external users use Forms Auth hitting [URL].

All that said, the solution works when the two applications are in the same site. Doesn't work when they are in different sites.

I dont want not logged in users to be able to access the files over a url address in the browser (like http://<server>/App_Files/Filename.pdf)

DataSource Controls :: Login SSMS Using Mixed Mode And Windows Authentication?

Jan 9, 2010

I had a problem login management studio (Sql server 2005) using windows authentication because it doesn't show me any server name to connect and if I put my computer name and user name (my-PCpatel) login was failed.

So, I decided to uninstall it and install it again using mixed mode authentication. After installation I select sql server authentication instead of windows authentication and put login name as "sa" and password that I had put it during installation. But the connect button is dark gray(the way I can not select it or press it on) while the other button (cancel, help, option) can be selected or pressed.So, why am i not able select or click on connect button?

Security :: Website Windows Authentication Fails When Enabling SQL Mixed Mode?

Oct 18, 2010

Just to describe the scenario. I have a website. This lives on a webserver. On that webserver is an SQL server. The website connects to this database using windows authentication. I have written a windows form application that connects to the SQL Server on the webserver. This application is being run from a location on out intranet. The Winform application use SQL authentication to connect to the database. The SQL Server didn't have mix mode authentication enabled. So I enabled it. The winform application could now connect to the SQL Server.

This is where it starts getting a little strange.

The Website that was already connecting find using integrated authentication starts failing with:


When you are enabling mixed mode authentication, you are adding another authentication method, why would the original Windows authentication fail?

Mixed Mode Authentication Against AD And Fallback To The Database If It Fail With Membership Providers?

Jul 12, 2010

my user will use form authentication against Active Directory or database. Theres no Windows Integrated Authentication there!!

What i want is when the user submit the authentication form, it will try to validate the user against Active Directory and if it fail, try with the database.

How can i do that? What i had in mind was to build a custom membership provider that will encapsulate the logic but im not sure how to start.

Visual Studio :: Edit & Separately Manage CSS Code Rather Than Work In A WYSIWYG Mode?

Jul 31, 2010

A few basic yes/no questions to see if I am expecting the impossible within VWDE:

At one point I thought I was given an option to create an external css file & have all styles automatically stored in the external file. Is there such a setting? ( Right now I have an external css file created & linked to the page, but as I work on the web page in Design view all new styles are created in the web page & I need to use the style manager to move them to the external file. )Can I tell VWDE to generate css for all formatting as I create a new table in the web page in design view? In other words, can I work strictly in web page design view yet have all formatting code - including the table layout - generated into the external css file?If I create style code for a web page table, does that style code need to be manually modified each time I add or remove rows from the table?Is there a VWDE funtion/tool to generate an external css file for an existing web page that contains embedded/inline styles? Right now I find that I need to individually move each style to an external sheet - i.e. Q1.If I were able in some way to create an external css file to handle all formatting for a given web page, would I have to manually create & maintain a second external css file to provide a printer-friendly format?Basically I have found so far that WYSIWYG editting in VWDE is ok up to a point, but support for CSS in Design view is very limited. It seems that if I want to employ CSS, I have to edit & separately manage CSS code rather than work in a WYSIWYG mode.

TI am hoping that even simple yes/no answers to the above will help me determine if VWDE is an exercise in frustration or worthwhile for me.

HttpHandlers / Modules :: Trying To Write An HttpModule That Will Work In IIS7 With Integrated Pipeline Mode AppPool?

Jan 2, 2011

am trying to write an HttpModule that will work in IIS7 with integrated pipeline mode AppPool. Within this module I need to access Session variables and to be able to capture the Session Start and End events. I have found a couple of articles on this topic that indicate the need to modify the behavior of the HttpHandler in PostAcquireRequestState to force the Session for the context to be initialized. The article I am using as a template is posted here:[URL]In my case I am getting the following error:

[NullReferenceException: Object reference not set to an instance of an object.] System.Web.PipelineModuleStepContainer.GetEventCount(RequestNotification notification, Boolean isPostEvent) +30 System.Web.PipelineStepManager.ResumeSteps(Exception error) +1112
System.Web.HttpApplication.BeginProcessRequestNotification(HttpContext context, AsyncCallback cb) +113 System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest wr, HttpContext context) +616

I believe that this error implies a problem with attempting to attach an event handler multiple times. I am aware that the modules Init function can be called more than once and have set a static initialization flag which ensures that I will only ever attach the event handler once.In the most condensed form my code is as follows:

public class HttpModule : IHttpModule, IRequiresSessionState

Custom Authentication Doesn't Work

May 11, 2010

I'm trying to upgrade my mvc 1.0 application that had a custom written login. I assign the authcookie like this:


And here if I debug _authRoles has "Admin" in it, and isAuthorized is always false.

If I check the "ticket" it has some: UserData = "Admin".

What can be wrong there? Is it the "User.IsInRole" that is different, or do I need to add something in web.config?

Does Forms Authentication Work With Web Load Balancers

Jul 28, 2010

I'm working on a web application that is using Forms authentication.

<authentication mode="Forms">
<forms slidingExpiration="true"
name="authToken" />

I'm seeing this cookie set in my browser when I log in:

The question is what happens when I put this website in a load balanced model? Where is the ASP.net session cookie being set? I didn't explicitly do it in code, so I assume it's happening behind the scenes somewhere in ASP.Net.

Also, If the session cookie is set by web server A, I assume web server B won't recognize it and treat it as an invalid session. If this is the case, I probably don't want to use it, right?

SQL Reporting :: SSRS 2005 "Mixed" Authentication Mode?

I have a web application where users can authenticate using either SiteMinder or Windows domain accounts. This is actually configured as two separate virtual directories within IIS 6. Both applications need to use the same instance of SSRS. Is it possible to configure the SSRS web application so that if a user is authenticated by SiteMinder it impersonates a Windows account, but if they are already Windows-authenticated that account is used instead?

Security :: Active Directory Can Work Together With Forms Authentication

I currently have a web application deployed on our intranet and it uses Active Directory to authenticate the user.It all works fine. But now im asked to somehow grant access to the application for outside vendors that are not part of AD, but they still need to keep the functionality of the AD as they dont want to manage all the users that currently use the application.Is this possible in some way?Currently users dont need to enter a password or username as they are part of AD, but users who are not get the " You are not authorized to view this page..."message. Is there any way to avoid that message and allow them to login using their own password?
