Pass UN/PW Authentication

Posted By:      Posted Date: August 28, 2010    Points: 0   Category :ASP.Net
 
I currently have a module which gets an incoming users IP and checks it against a database.  I have a web service/ application which I now have set up with Basic Authentification.  I would like to check the users IP, if they are in a certain IP range i want to pass their UN/PW (which i get from the database) through.  This way my services are blocked by UN/PW but my clients, coming from certain IP ranges dont actually need to enter them.So far: I am here-  I can check and authenticate IP and grab a UN/PW which is stored in a database.I Know- I need to grab the 401 error and the WWW-Authentication header and use that to structure the return with the UN/PW, but I dont know how to do this.I am doing all this in C# and implementing this as a HTTPModule.  Any help would be great, Thanks!

Windows Authentication doesn't work after change of admin pass

  

Hello.

J have read many answers about

Login failed for user ''. The user is not associated with a trusted SQL server connection

error, but I don't want to mess up in my sql server so I want to be sure that what I do is OK.

Environment description:

In my company, we have our own application wchich we use to connect to database. All users use SQL Server Auth except me. I can log using Windows Auth from server and from my second computer.

Now everything works fine.

- My comp is in our domain 'OurDomian'.

- On server in AD is admin account 'SqlAdmin'.

- In MSSMS in Security->Logins there is account: OurDomian\SqlAdmin

- on my comp account OurDomian\SqlAdmin is added

I can log to sql server from  my comp using 'Integrated Security' in application with no problem.

Problem description:

Problem starts when I change SqlAdmin password on server.

When I connect from my comp I get the above error. But when I connect from server there is no problem.

I searcher application code and I don't think that I have to change somthing in it. Probably I have to change something with account and permissions.

1. Will it bee enough to delete and add again 'OurDomian\SqlAdmi

Need Help Configuring Pass-Thru Authentication (ASP.NET 4.0, IIS 7.5, SQL 2008 R2)

  

I have an ASP.NET 4.0/C# web application that I have deployed to a web server. However, pass through authentication is not working. I'm getting an exception in the app event log saying that, "The underlying provider failed on Open". When I check further, it is attempting to login to the SQL Server as the computer$ account.

What I want to have happen is the following.

  1. User loads web application in browser.
  2. Web browser passes windows authentication automatically to IIS 7.5.
  3. IIS passes authentication information to SQL Server 2008 R2.
  4. SQL Server checks that the user has permission and fulfills the request.

I have the following in my web.config.

<identity impersonate="true" />
<
authentication mode="Windows" />

Explained: Forms Authentication in ASP.NET

  
This module explains how forms authentication works in ASP.NET version 2.0. It explains how IIS and ASP.NET authentication work together, and it explains the role and operation of the FormsAuthenticationModule class.

Using Forms Authentication in ASP.NET - Part 1

  
Classic ASP developers often had to "roll their own" authentication scheme, however, in ASP.NET much of the grunt work has been taken out. This article outlines how things have changed and how FormsAuthentication can be used to secure a Web site with a minimal amount of code.

ASP.NET Forms Authentication - Part 1

  
Often, in legacy Web applications, users authenticate themselves via a Web form. This Web form submits the user's credentials to business logic that determines their authorization level. Upon successful authentication, the application then submits a ticket in the form of a cookie, albeit a hard cookie or session variable. This ticket contains anything from just a valid session identification access token to customized personalization values.

ASP.NET forms authentication with roles

  
.A timeout is specified in minutes. This is "time since last request" not the "time since login". If a login is indicated to be persistent (described later) this is ignored.
.A protection method is specified for the cookie.
Next I wanted to specify a folder to which access is restricted to people who have logged in. To do this I entered the following code in the web.config file (beneath

How to Pass Values Between Web Pages ASP.NET

  
You can pass information between pages in various ways, some of which depend on how the redirection occurs. The following options are available even if the source page is in a different ASP.NET Web application from the target page, or if the source page is not an ASP.NET Web page:

Use a query string.

Get HTTP POST information from the source page.

The following options are available only when the source and target pages are in the same ASP.NET Web application.

Use session state.

Create public properties in the source page and access the property values in the target page.

Get control information in the target page from controls in the source page.

Pass a grid column value to a Modal

  

Hi, I have a requirement to hide a field called details on a gridview and show it in a jQuery modal dialog when users click on the Customer ID hyperlink. This grid is created programmatically. I will be hiding the details column via the CSS display:none property. Does some one know how can I pass the grid's selected hidden column value to the modal? Here is some of the code I started:

            GridView mygrid = new GridView();
            //.....................................More columns code for the grid

Web Matrix + Windows Authentication

  

I'm curious if its possible to get windows auth working with asp.net webpages/webmatrix.

I've got it published to IIS with windows auth turned on and anonymous/forms/basic turned off.

I'm guessing the WebSecurity Helper probably won't work here but can you access User.Identity.Name etc?

Sorry for the newbie questions, I've only just started working with asp.net ^^,


Problems with Forms Authentication in DD 4 site

  

Hello,  I am seeing a strange problem with Forms Authentication in my DD site.   A user logs into and can view/edit/delete data all day, but when they execute a Custom Filter against data (for example , a control DynamicData/Filters/CustomerLastNameSearch.ascx ) then the site auth fails, and redirects to the log in screen.

in web.config I have

     <authentication mode="Forms">
            <forms name=".Star" loginUrl="~/Login.aspx" protection="All" defaultUrl="~/Default.aspx" path="/" timeout="43200" cookieless="UseCookies" />     
        </authentication>

Offhand, I am thinking two things : that DynamicData/Filters path requires some special handling for some reason, or the control extension ascx is causing auth to get confused.   Has anyone else experienced this or have any suggestions?  Thanks!


Pass ASP.NET membership identity object across domain?

  

I am trying to figure a way to SSO with ASP.NET membership and role model.

I can implement custom membership provider which consume web services hosting on a server.

With encryption of data. No problem.

But my question is, If I sign on a website with my provider, got my identity object on that application,

could I pass it to another website on another domain which use the same provider and by doing so, do not need to login again?


If this is possible, I am going to implement this solution. Please tell me what's your take on this.


Sharing authentication ticket between two applications

  

Hi all,

I have two web applications:

1. http://www.mysite.com - primary app running at the root of the web server

2. http://www.mysite.com/second_app - running in a virtual directory


At user authentication, I'm using FormsAuthenticationTicket to set up authentication cookies. Is it possible to share the same cookie for both the apps?

Any help would be much appreciated.


Many thanks!
