Security :: Sharing Forms Authentication Between Framework 3.5 And 4.0?
Nov 4, 2010
We have multiple applications written in 3.5 SP1. Our new application is being written in 4.0. They all reside inside the same domain, and all the other applications share the forms authentication security ticket by setting a machine key, and setting the Name of the forms tag.
Authentication in each application still works, HOWEVER:
* In the 4.0 app, if you log in, and then go to one of the 3.5 apps you are not logged in
* If you log into the 3.5 app, you are not logged into the 4.0 app, but you are logged into all the 3.5 apps
* If you log into the 4.0 app, you are LOGGED out of the 3.5 app even if you were logged in before.
The <machinekey> tag is there and set the same in all apps
The <forms> tag is set up the same in each app except for the LoginURL
The <membership> and <rolemanager> tags are also set up the same in all apps
Is this possible between frameworks? If so, do I need to do something differently? I really would like to avoid porting all the other apps to 4.0, or porting this down to 3.5

I have 2 almost identical asp.net (vb) applications. 1 Development and 1 Production.
They use forms authentication that is configured to run in SQL server. Both apps use the same aspnetdb database but have different application names.
The problem I have is:I have an Identical login for each app (same username, same password), but If I change profile information for that user in the development app, the changes are reflected in production app. This isn't what I want.

Previously, I have implemented two separate ASP.NET Web Applications, one as a virtual application in a subfolder of the other, which successfully shared forms authentication as described at [URL]
(basically, setting up identical <forms> sections in the Web.config, and keys in the <machineKey> section)
Now, I am trying to do something similar to get BlogEngine.NET (which is a Web Site, not a Web Application) to work sharing forms authentication with a Web Application of mine. I have tried both putting it as a virtual application in a subfolder, and setting it up as a separate IIS site (same domain name, different port number), but I can't get the authentication to work at all: when I go to the blog while logged in to my Web Application, Page.User.Identity.IsAuthenticated is always still "false".
I'm really not sure how to even start debugging this, since the forms authentication is handled before any of my code runs.

I have 2 applications. One on asp.net webforms [URL] which should provide authentication, user logs in and I can use the cookie to authenticate on my asp.net mvc app located at [URL]. All I'd like to do is able to access the cookie so I can get the userId that was stored in it using the FormsAuthentication.
They use normal authentication provided by microsoft;
<authentication mode="Forms">
<forms domain="test.com" loginUrl="Default.aspx" protection="All" path="/" requireSSL="false" timeout="45" name=".ASPXAUTH" slidingExpiration="true" defaultUrl="Default.aspx" cookieless="UseDeviceProfile" enableCrossAppRedirects="false"/>
</authentication>
This cookie should be accessible to any submain on [URL] right?

I have developed the authenticated rss feed using the basic http authentication for my site.I also have the admin module for the site which uses the Asp.net Forms Authentication .Both are in the same project.When i turn on the forms authentication module to None in my web.config.My rss feed authentication works fine(the browser pop up the dialog box for the username and password) and upon entering the username and password the rss feed gets displayed.But with forms authentication turn on when i click the rss feed link i am getting redirected to the administrator login page.
If i set my authentication mode to none than the feed works like dream but the admin module do not work as it uses forms authentication.
How can i resolve the conflict for that one.I am using the asp.net mvc filter on my feed contoller to pop up the dialog box for the username and password.

I'm developing an internal booking sytem. Users log in to the sytem and can view existing bookings and search for bookings. They can also create new or edit existing bookings. When completing such actions I need a confirmation prior to completing the booking or updating the recorded. The confirmation is based on a reauthentication of the user.... in otherwords he needs to enter his passord again.
How can I achieve this? The system is internam and I'm using Forms Authentication. I an also using roles as som of the admin forms can only be viewed by administrators.

I have a scenario with three applications:
1) Portal: where user executes login
2) Site1: after login at "Portal" user is able to use Site1
3) Site2: after login at "Portal" user is able to use Site2
I just need to execute a validation in Site1 and Site2, to validate if they (users) did login at Portal1.
Something like (in site1 main page page_load).
{
if (notFromPortal)
{
//redirect to Denied.apx
}
}
How can I do this in a simple way? With cookies? Does somebody have a url with sample?
My security requirements are almost zero. I just wanna prevent that user put a url from Site2 in browser and see a Site2 page.

This could be very straight forward for some of you, but I got caught up. I am doing very simple test - browsing from IIS Manager to see the default page or "under Construction", however I am being challenged to provide my login credential . When I provide my login credential, I am able to see the default page. I wanted to see the default page without providing my credential since Enable anoymous access + basic authentication I am simply wanted to see the default page asit is working on other servers except this one. I have included screen print to make sure may question is clear.

In rails I could do something like this to make sure a user is authenticated before accessing an action in the controller:
before_filter :checked_logged_in, :only => [:edit, :update]
I was wondering if ASP.NET MVC had something similar or if there was a framework out there that could essentially do something like the following:For certain methods with actions that take a certain parameter, I want to point the action to a method, check to see if the user owns that object, and if so, proceed to the controller action. If not, I want to redirect him to another action where I can show him he has invalid credentials. So basically I am looking for a sort of "before_filter."

I have to invoke SSIS packages from web service in the most secure way. I think that windows authentication will be secure but i am not sure. I do not have much knowledge about how to achieve this and the information on the internet is very distributed.

We use Sharepoint to control our websites. We build the sites, then load them into the sharepoint server. My question is if I use windows authentication, how can I get my role security in my web config file to coencide with the asp.net controls that use the Forms authentication. Is there a differenence? Our security uses a session variable for security but there is no where to set up their permissions except in active directory. I hope this makes sense because I would like to implement the LoginView with Role groups but how can I give them the role="administrator"? Do I have to go into active directory and give them these permissions(would take awhile due to the size of the company)? Or do I have to set up priveladges in the web.config file for each user(difficult I think)?

I'm writing a simple Intranet application using windows authentication. I want to restrict access to Safe/UCantSeeMe.aspx. I am aware of the AuthorizeAttribute, but this only works on methods. I also found a good post on doing this with the MVC pattern, but I'm not using MVC. This can be done with roles in forms based security. I read on MSDN that using windows based security means roles are based on groups, but it doesn't go into any detail. how can I restrict access to Safe/UCantSeeMe.aspx?

We are using membership provider for LDAP authentication. It is working as it should.
But what all configuration settings I have to do so that
all the future requests to this application run under the security context of the Logged in user account not through the some default user set in IIS.
We need to have this working because all the permissions on the database are based on the logged in user.
We are using form authentication for LDAP authentication. And having impersonation = true in web.config.

I have an application that has a user Login Control (provided by ASP). I am just now working with the integration of a dataBase created in MS visual studio 2010, to a developed website created in MS visual web developer 2010. My main goal is to create an authentication ticket that enables a user to be able to see a dataBase information only after that user has been successfully authenticated.
Up to now I'm able to see the dataBase when i run the website even if I'm not log-in, how i can create a home page that tells the user to log-in and once that user has successfully log-in it redirects the user to another page where the user can see the database and how I can add information to that dataBase only to specific members

I have the same exact problem here [URL] I have a multi-project solution with role based security. I login with admin and hit logout. Then, I can login with a user that has a different role and access an admin page by typing the address. Once I try to do something on that admin page that postbacks then I get kicked out and redirected to the login page. If I don't write in redirect to login page in logout page, I have to hit logout twice for logout to work properly. Also, it works fine if I close the browser and run a new browser.
Web.config:
<authentication mode="Forms">
<forms name="AppAuth" path="/" loginUrl="login.aspx" protection="All"
timeout="5" slidingExpiration="true" defaultUrl="default.aspx"></forms>
</authentication>
[Code]....
Something else I am wondering is if there is a way to redirect a logged in user to default page instead of login page when they try to access a page they don't have a permission for access.

I understand that we can easily secure the menu pages by enabling SecurityTrimming and putting role information in web.sitemap.
But my problem is that we have to use a 3rd party authentication piece. The ASP.NET application gets the UserId and roles from the authentication module.
I need to show/hide ASP.NET pages based on the incoming user's roles.
Is it possible somehow to use web.sitemap with these roles?
Or should I come up with my own way to map a web page to role/s?

I am developing a small website in vs-2005.
Here I am using forms authentication and I have used an access database. I have put the db in App_Data folder and declared the connectionstring in web.config. The problem I am facing is that when I request any page without logging in the browser displays the requested page. At the bottom of the page there is a script error when I check the details it says Sys is not defined. Has this something to do with this issue??
In web.config file I have added the following lines in the <system.web></system.web> section.
<authentication mode="Forms">
<forms name=".ASPXFORMSDEMO" loginUrl="Default.aspx" protection="All" path="~/" timeout="30"/>
</authentication>
<authorization>
<deny users="?"/>
<!--<allow users="*" />-->
</authorization>
On login button click after comparing userid & password I am using the foll stmts:-
If code = 0 Then ' code 0 means match for userid and pwd
FormsAuthentication.RedirectFromLoginPage(txtuserid.Text, False)
Else
Response.Redirect("~/Default.aspx")
End If
