First I was hoping using the IP address check I will be able to do that but due to proxy many user will have a same IP address.

Security :: Prevent Multiple Concurrent User Logins For The Same UserName

Jun 2, 2010

My application is windows authenticated. The application pulls JUST the userName from the current windows account. Then I provide site access to this user depending on his account privileges. If his userName belongs to the admins list he is directed to admin screens. If his username belongs to users list he is directed to users screens. I handle this security in C# and some SQL tables(No membership provider and no Active directory security in the app).

I need to be able to prevent multiple concurrent logins for the same userName.

Security :: Multiple Logins And Login Types In Default .NET Membership Provider?

Sep 8, 2010

What do you think about an ability of having multiple logins and login types to be attached to the same user? Let me explain this by showing how database schema can be re-factored to support this model:


Remove [Password], [PasswordSalt] columns from [Users] database tableAdd [Logins] table with one-to-many relationship between [Users] and [Logins] tables.This will allow one user to have multiple credentials attached to his or her account of different types such as Username&Password, Windows Live ID, Open ID from different providers

You will be able to restrict allowed login types and OpenID providers in web.config

So.. do you think it is a good idea to add support of this model into ASP.NET 4.5/5.0 membership service?

Preventing Multiple Logins?

Nov 24, 2010

I'm using the "cache tecnique" to prevent multiple logins. Reading in this forum I have read the following code:

Global.asax

[Code]....

Login.aspx
[Code]...This code works fine, If the user is already logged the second login is not permitted. But....

But if I make the logout (destroing all my session variables) and I try to login a second time... it's not possible, I read that the user is already logged!!I have also tried to clear the cache after the logout but nothing changs, even if it is illogic because the code must work even if I don't do the log off...

How To Allow Multiple Logins With Forms Authentication

Feb 16, 2010

I have a problem with membership authentication. I have two websites, website1 and website2, and both of them uses forms authentication with SQL membership provider (SQLEXPRESS). I have two scenarios:

Case 1:don't publish the website1 and try to login website1 with user1 -->Works ok
don't publish the website2 and try to login --> it displays the previously logged in user (Website1 user)-->Perfect

Case 2:publish the website1 and login-->works ok
publish the website2 and try to login--> it does not show up the site1's logged in user (No idea why)

then login into website2 and open website1-->it does not show up the website2 logged in user or any user...It looks like something wrong with cookies....

my web.config looks like this:<authentication mode="Forms">
<forms loginUrl="~/LogOn/LogOn" timeout="2880" protection="All"/>
</authentication> [code]....

Security :: Restricting Access To Folders And Pages?

Nov 16, 2010

I'm using user membership and roles. Below is my web.config for subfolder restriction.

[Code]....

The way I have above, no one can access this folder, mySub, except Administrators, Editors, and Members. However, here's what I want. I want to allow all and any user to the default.aspx page of this mySub folder and denied any other pages if they're not Administrators, Editors, and Members. One last thing, also denied access to addWord.aspx if they're not Administrators and Editors. I know I can list all the pages and give them various permission but I do not want to list all the pages. What's the best and easist way to accomplish this?

Security :: Restricting Access To An ASPX Webform?

Dec 11, 2010

I have seen an existing post which explains how you can restrict access to an ASPX page using:

[Code]....

This works as in it keeps those who are not a member of Administrators AD Group from being able to view the webform but for some reason when I implement the above it locks even the Administrator user out which is not what I wanted at all.My web.config is as:

[Code]....

As you can see I have tried to restict it also through the web.config file but neither approach has worked.

Security :: Restricting Access To One Page Not The Whole Website?

Jan 29, 2011

I'm trying to restrict access to one page on my website. However, the code I'm using doesn't seem to work for this purpose. I can get the code to work by removing the following out of the web.config.

<authorization>
<deny users="?" />
</authorization>

This works fine by preventing access to the page unless a password is entered. However, I've realised that if I type the page name into the browser this will by-pass the login page and allow access to the page I want to lock down.

Feb 16, 2011

I currently have an app which using Active Directory for authentication. In other words, the IIS virtual directory is setup Active Directory authentication and I do no have to deal with it at all. If you are on the domain, you can get in.

Some customers now also want to add a feature where they can log in using a standard userid/password combo. The scenario being a contractor coming in for a few days with their laptop and need access to the app. There is no point of creating an Active Directory account for such a person.

Security :: Multiple Roles For Multiple Page Access?

Jan 20, 2011

I'm planning to make a page that has about 10 different pages for varying use, for example, stats, data entry, reports, logistics, audit, sales, promo, etc etc. I'm anticipating there will be many combinations as to what pages a user may have access to, for each page, a user ought to be authorized to either enter new data, edit data, print and/or just view.

My questions are :

1. can membership & roles be used, once user is logged in, to display links to all the areas of the web app he is allowed access to?

[code]....

2. besides having access to a particular page, a user should, as mentioned before, be authorized to either enter new, edit, print and/or just view data.
3. Is there a preferred/better method to handle this besides using membership & roles?
