I have an Intranet web site that uses Windows Authentication and when a users password expires the do not get a prompt letting them reset it.

How can I trap for expired passwords and allow them to change it like they can with OWA?

Security :: Require Https To Safeguard Windows Authentication Credentials?

Nov 9, 2010

I have a zealous network administrator who insists that we must use https on an intranet web application in order to safeguard user's credentials. The app is an asp.net web app that uses Windows Authentication to automatically identify users and log them in. There is no login dialog and user's never enter their login or password. The application does not process any confidential data, and the only rationale for requiring https is to "safeguard" users credentials. Additionally he stated that ntlm can be easily hacked.I responded with some information from an MS white paper on Windows Authentication that said it was the recommended way of authenticating users, and that user's credentials were safe because their passwords are not transmitted across the network when the application authenticates them since it sends a hash of the password.

C# - Can Reuse Built-in IIS Authentication But Provide Own Credentials Checking

Feb 14, 2011

I'd like to use built-in IIS authentication with non-Windows accounts. There's this module that does that for basic authentication, but it in fact does both the authentication and credentials checking.The problem is I also need to support digest authentication and I could try to do it, but it would be a lot of hassle - I need to generate challenges ("nonces") securely, store them and check for replays, etc. - lots of things I can screw up and make determined attackers happy. So I'd prefer to reuse the digest authentication functionality in IIS, but use my own module for credentials validation. How can I do that?

Security :: Change Password For Windows Authentication

Oct 12, 2010

Using windows Authentication... is it possible to progrematically change a password?

I tried using several ways to do this. I tried using the ChangePassword control. This tells me that minimun characters is 7 even though I have more then 7 characters... I also tried using this method:

[Code]....

The user is always null... and I am assuming this is because this object is indended to use with Forms authentication.

All I want to do is have an option for users to change passwords. Is this possible with Windows Authentication?

Integrated Windows Authentication - The User Changes Password And Is Prompted To Login Again - Why

Mar 22, 2010

I am working on an application that uses windows authentication. Within this application, we give the user the ability to change their password. The user can change the password just fine. However, after they change their password, that is when things get weird. Sometimes they can navigate through the application just fine. Other times, they click on a link and are immediately prompted to supply credentials. Occasionly they can click on a link but upon a second click they are prompted to supply credentials. Does the browser keep a token to the original credentials and use this when they request the next page? If this is the case, why can i continue using the site sometimes? Can I change the password and then assign that token to the request?

Security :: Password Prompt For ASP Website Hosted On Intranet Using Windows Authentication

Jul 8, 2010

We have developed a website in asp.net using windows authentication and deployed it on the intranet (IIS v6.0). Most of the times, when users try to access this website they are taken straight to the website, but occasionally some users get a prompt to enter their windows username and password. I understand that this could be caused because of several reasons like:

Cached active directory password. Recently active directory password changed. Active directory account locked out. I want to fix this issue for good because it is annoying the users.

WCF / ASMX :: Windows Basic Authentication-Credentials Retained For Further Calls?

Aug 25, 2010

I have an XML web service where the authentication used is BASIC WINDOWS. Following is my client code to connect to the service.

[Code]....

Now, the issue is that the client is really authenticated only in the first attempt(First time I execute the code in VS). Further attempts succeed even if the code to assign credentials is commented or even after providing wrong user id/ password. I ensured that the server is hit each time(Just to make it clear that it not just because of client side caching).Is this the behavior of Basic authentication/credential cache. I would prefer the client be authenticated each time he hits the server.

Security :: Use Membership Store For User Settings With Windows Authentication

Sep 1, 2010

I am evaluating ASP.NET Membership for an intranet Silverlight app. I want users to be automatically authenticated for my application with their windows logon. Thus I configured Windows Authentication. I would like to store user settings like email-address in using the SqlMembershipProvider and not AD. It seems that storing user settings using the SqlMembershipProvider is not supported with Windows Authentication. Is this really so (using .NET 4)?

If so: What is the rationale behind this? IMHO authentication, user settings and authorization are distinct aspects. User settings could easily be stored (identified by user name) using the SqlMembershipProvider with authentication and password management being supplied by Windows. What is the recommended solution for my scenario?

How To Redirect The User To Password Recovery Page With Forms Authentication

Nov 29, 2010

I am a beginner of asp.net..I currently have a login page with forgot password link button on the bottom of the screen. I am also using forms authentication to prevent an unauthorized user from accessing the other pages. The authentication seems to be working fine except for one thing. It prevents the user from accessing the password recovery page once the user click on the link button. How do I allow all users access to the login/password pages and also prevent them from viewing the other pages if they are not authenticated?The code below is to prevent from other anonymous view other pages without access. But i got no idea on how to allow them to access password recovery page...

<authentication mode="Forms">
<forms loginUrl="/Presentation/Display/Login.aspx" name=".ASPNETAUTH" protection="All" path="/" timeout="120" cookieless="UseDeviceProfile" slidingExpiration="true"/>
</authentication>
<!-- This section denies access to all files in this application except for those that you have not explicitly specified by using another setting. -->
<authorization>
<deny users="?"/>
</authorization>

Iis 7.5 Dns Windows Authentication Page User Identity Not Working?

Feb 7, 2011

In IIS 7.5 server I have a website apps.mydomain.com. Site binding for this website is:

IP: All Unassigned

Port: 80

Host name: apps.mydomain.com

In DNS there is an ip address pointing to apps.mydomain.com. Site comes up fine when browsing to this hostname.

I want to get current windows logged in username from asp.net web apps. I enabled windows authentication and disabled anonymous. Using this ASP.Net code to test:

Response.Write(Page.User.Identity.Name);

However, browsing to http://apps.mydomain.com/site/ the application pool identity shows as the Page.User.Identity.Name value and not the current windows logged in username.

If I browse to http://servername/site/ then Page.User.Identity.Name will return current windows logged in username.

Is there something else I need to configure to get the current windows logged in username when using host header?

web.config:
<?xml version="1.0"?>
<configuration>
<system.web>
<authentication mode="Windows"/>
</system.web>
</configuration>

App pool config (left out "handlers" for brevity, there's a 30000 char limit):
