Security :: Access Denied For Logged User (anonymous User Is Fine)
Jan 7, 2011
I deployed a website where a logged user or an anonymous user can select data and download a XML file. The website generate the XML file in the server and then deliver it.
It works fine in my development environment, but after deployment, the anonymous user can download the file, but the logged user receive this error:
System.UnauthorizedAccessException: Access to the path 'd:HostsLocalUserheringerwebsiteUpload20110107094051.xml' is denied.
It is weird that as anonymous i can do it.
The website server help states this:
"Grant write, modify, delete access rights on website's folder
Your website executes under unique user account that by default has full control over the website's folder.
So your application can create, open, read, write and delete files and folders inside of your root folder.
There is no need and no way to change this permissions.
If, when running ASP.Net application, you still unable to create file or update it, you have to check your Web.Config file for "<Identity impersonate..." tag and remove it.
The only exception is when the application tries to modify a file or folder in "Application_Start" event of Global.asax file. This is by design that user authenticated only after the Application_Start even. Before the user is authenticated your website runs under an identity of Application Pool which is "Network services". That account doesn't have access to the folder of your website.
To make it work you eather have to move the code that tries to modify files or folders out of the "Application_Start" event of the Global.asax file or inside the event you'll need to impersonate your user by code."
But i am not using impersonate and the tag is not in my web.config.
i am working in asp.net and csharp, we have 10 user, but certain user only need to put dataentry. how to enable and disable based on the user to access certain form ,like add, modify view options.
I would like users to upload a profile picture when they register, and to then show that picture in a picture box control when they are logged in based on that specific user.
Our users are only only allowed to log into our site from one location at a time. If they attempt to login from a second location, how do I log them out of the first location?
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.
the Web Part for anonymous user and authenticated user is displayed differently. I faced this problem twise. First time when used Silverlight control in the Web Part and second time when used devexpress control in the Web Part. In both cases problem was with displaying for anonymous user. Silverlight control didn't display. Devexpress control lost it's styles. Both controls had properties that pointed to files. Silverlight control property pointed to the XAP file, and Devexpress control property pointed to the CSS file. It seems to me, that for anonymous user the Web Part cannot find this path or doesn't allow to link to other files.
I have been creating a website using the SQLMembershipProvider. I have been using an administration account to create the back-end system for generating the users fine for about 2 weeks. I now have more users created and I can log in fine. However, when I log in as the newly created users, they can get to the page they are after, but if they refresh the page or redirect to another page, they get redirected to the login page. I have checked permissions, iis recycler, session state and security setting in my web.config (posted below) but nothing has fixed it. It cannot be IIS because it does it on my development machine as well as on the actual webserver and it works fine for the admin user.
I have used membership provider to implement my system. The system administrator can list the users. What I want to do is, administrator should be able to sign-in as the selected user. I can sign out administrator by FormsAuthentication.Signout but how can I sign in as the selected user? Passwords are hashed so I can not retrieve the passwords.
I've successfully made a custom membership provider that connects, queries, and updates my custom Oracle database. I found a good sample on MSDN. I also found documentatio on the provider itself. However, I cannot find anywhere example calls you have to make for the different actions within the web pages themselves. Where can I find that?
For example
How do I check if a user is already logged in? What do I do when a user hits the login button? How does each page get the user that is logged in? etc.I am not using the asp login control. I have custom form, custom data, and custom graphics.
All I'm trying to do is pull the current user's login name from Active Directory. I've tried User.Identity.Name.ToString, which returned nothing at all. I tried Environment.UserName.ToString, Which returned "NETWORK SERVICE" which is not the firstname.lastname username that I was expecting.
I have one application for collection centres in the city in which ADMIN will have access to all pages in it.In which I have added functionality for admin to see Online users/offline users collection and there collection center name.How can i see the users online automatically when they will be logged in on application.Like we all see in google talk, yahoo messanger, etc like that onlyI also want to keep the option like whether to view only online user or offline users etc.I have tried the following code for getting the Ip address for the computer..But I am unable find how user should be shown as active
ip=Request.ServerVariables("HTTP_X_FORWARDED_FOR") ; if (!string.IsNullOrEmpty(ip)) {
If a user who is logged in wants to delete his own account, why does login status still show him loggedIn even when user has been actually deleted.What I want is when user deletes his account he should get logged out also at the same time ....How do i log him out ?
[Code]....

I'm using the defualt membership provider, i created a table and used the gridview on the logged in user page to show his information such as address e-mail phone zip code etc,, how can i do this without writing a code?
i have a login form where it validates 'username' and 'password' against a datbase table. After a user logs in, i would like to show their details such as image, name, etc in a detailsview.
In my application, I have users request accounts, and then an admin goes in to approve or reject the account. When the admin approves the account, the create user wizard is used. After the user is created, I set the new user's role, and update a few other items in my database for user tracking, and send out an email to notify the new user of their account status. Here's the kicker: Once this new user is created, the admin, is now logged in as the new user. How is this happening? And how do I stop it? Here is my CreatedUser code, scrubbed of non-pertinent code. [Code]....
My 3.5 app uses Forms Authentication. I create an authentication cookie (ticket) with an expiration date of one day. The cookie's IsPersistent is set to True. I do not use any session variables. Session timeout is the default 20 minutes.
Here's the problem:
When the session times out in 20 minutes, the user is redirected to the logon page even though the authentication cookie has not expired.
Why does this happen? I thought the session and the cookie were independent of each other.
I new to ASP.net and have created the registration form and login using the wizzard. This data is now stored in the relevent tables provided by asp. I also have created an extra table with profile information like address, phone number etc and a USer ID field that links with the aspnet_users table.
I am trying to display the details of the user when they log in so for example...
User logs on, clicks profile page, profile information can be added and viewed.
Now the problem is I am using a Select statement to get the data but when I do a Where statement im not sure what to put to basically say where userid = current user id logged on.
a user loged in and he wants to delete his user. how do i make a delete query that refers to his userID how do i get the user id of the current logedin user?
My Windows Server 2008 server hosts an ASP.net application that uses impersonation. The application works as long as the user being impersonated remains logged on to the server. However, when the user logs off, clients can no longer view the web pages. They get a cryptic error instead. How can I configure the server to work without the impersonated user remaining logged on?
I want to capture when a user logs in and his username. I am using a login control inside a anonymous temp[late of a login view control. on the logedin event of the login I have this code:
Dim log As Login = CType(sender, Login) If Not log.UserName = "bcweed@live.ca" Then Dim mil As MailUtility = New MailUtility mil.ClientLogin(log.UserName) End If
but log.username is always empty and so is the page.user.identity.name and the page.user.identity.isauthenticated always returns false this even thouhgt this is the LogedIn event of the login and also I "just loged in" I really did.. is there a way to capture this is the global.asax?
Im using forms authentication on a site. I have a requirement where I have to log the username of the user that is currently logged into the computer. It is not a public site. It is an intranet site at work. I have tried several different methods but they all return the username of the user that is logged into the site. The methods I have tried are below. Note: I would perfer to log the username without the domain.
