Security :: Impersonation Of User Accessing File Server From Outside Domain Failing

Dec 23, 2010

I have a machine in MyDomain on which i have deployed the website and file server as virtual directory. For file server i have created an application pool with identity as UserName and Password. And file server directory setting as Integrated Windows Authentication instead of Anonymous Access. When i am accessing file server from outside the domain then it is asking for user name password. After providing the credentials it open the file. Now i am trying to access the file server from wbsite using the machine outside the domain.Before accessing i am impersonating the current user with user which is present in identity. But after redirecting to the file server url it is again asking the credntial. why it is asking the credential if i have already impersonated the user.

Security :: Impersonation With Domain Account Without Joining The Domain?

Sep 28, 2010

My feeling says it's not posible but anyway I am curious if there is at least a workaround for accomplish this.Basically I am working at my client site and my machine is not connected to the domain.What I want to do is running a web application locally under a domain account, and using the webdev server.The webapp uses the default authentication, windows authentication that is.I tried using impersonation with domainuser & password but I got the following error Could not create Windows user token from the credentials specified in the config file. Error from the operating system 'Logon failure: unknown user name or bad password.I have to mention that the username and the password are correct.

Security :: Get Remote User From A Non-domain IIS Server?

Jan 27, 2011

Can I get who the remote user is on IIS Server that is not part of the domain without challenging/prompting the user? I am thinking not, but wanted to see if anyone had a different answer. I added the server to my intranet zone but that didn't cause IE to send any user information. Or maybe it did but since the IIS server is not part of that domain it can't do anything with the user information. I am looking at the ServerVariables in the Request object.

Security :: Run Batch File On Another Server Different Domain?

Feb 4, 2010

I have a batch file on another server on a different domain or network that I need to run from an ASP page. I found a simple enough script that opens a CMD prompt, goes to the location of the batch and runs it. If everything is on the same machine, it runs fine.

The issue I've run into now is that the batch file is on a file server and the ASP page is on a IIS server. The File server is on a internal network (separate domain) and the IIS server is on an external network (or different domain), both servers are hosted here.

When I try it and look at the event logs I can see a failure audit and its trying to login with the machine name.

Security :: User Be Logged In For Impersonation To Work?

Jun 4, 2010

My Windows Server 2008 server hosts an 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?

Security :: Active Directory User Impersonation With Forms Authentication

Aug 31, 2010

I've written a small ASP.NET 3.5 application to allow users to update selected account attributes on their own. Everything works fine when I use Basic Authentication, but because the dialog that is presented is less than ideal, I'd like to use forms authentication to give the users more instruction on how to log in. My problem is that in order for the user to update their account information, I have to have the application impersonate them for the update actions. I've scoured the internet trying to find a solution to my issue, but nothing fits or works. I have tried setting the web.config:


I also tried using the LogonUser method to create a user token and backend the authentication that way, and it doesn't work either.

Security :: Impersonation / Getting Error / Login Failed For User 'NT AUTHORITYANONYMOUS LOGON

Aug 16, 2010

I'm running IIS 6.0 on a Windows 2003 server and running an ASP.NET 4 application which connects to an SQL Server 2005 database on another server. I have my Default.aspx page set to Windows authentication with anonymous access disabled.

When I load up the page it asks for a username and password (as expected), I enter my credentials and it comes up with the following error:Login failed for user ''. The user is not associated with a trusted SQL Server connection.

If I add the following to my web.config file: <identity impersonate="true"/> then I get the following error:

Login failed for user 'NT AUTHORITYANONYMOUS LOGON'.

And if I add the <identity impersonate> tag set to true and with my username and password included it connects successfully.

I can't leave this in there as I want each user to connect as themselves, so why is the server not using the credentials that I enter when prompted to connect to the database ?

Security :: Impersonation Error / .NET User Account Has To Be Given Permissions To Access The Folder

Jun 18, 2010

I wrote an application that I'm trying to run on a godaddy domain I bought. I need to read a file in a folder that I did not give read access to so that your average user cannot see in the informaion in that folder. I assumed that the program would have the same credentials as myself because server-side code. Turns out I am wrong. When I go to use the application it throws an access denied error saying that the ASP.NET user account has to be given permissions to access the folder.

After talking to two different tech support people at godaddy I've come to the realization that they are either dumb or lazy (or a combo of the two).I came across some code that you can put into the web.config file that would allow the application to impersonate a user, which would work great to use myself as the impersonated user. However it seems that godaddy cannot give me the name of the server that my domain is on (that's understandable) so I don't know what to put in the identity tag to get this to work.

Here is the code I found:


(of course I filled in the username and password with the correct info)

When I went to use it again it threw this error:

System.Web.HttpException: The current identity (PHX3username) does not have write access to 'C:WindowsMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files'.

Web Forms :: File Upload Failing On One Server?

May 7, 2010

I have a web form that allows the user to upload a file to the web server, that file is then read into a database. This process works on my local pc, my dev box and one of my qa servers.

Security :: Accessing User Id Immediately After User Signed Up

Jan 8, 2011

On our website users can sign up. The sign up controls (converted to a template) has the usual text boxes and then the create user button. When pressing this button the account is created. After reloading the website, the user can see his credentials in his 'my account' tab. Question: How can we access the newly created user (especially his userid) right after the create user button was clicked? Right now this does not work, we can only start accessing this after the page has been reloaded. But surely the account is created the instant the button was pressed. I have tried this:

MembershipUser myObject = Membership.GetUser();
UserID = (System.Guid)(myObject.ProviderUserKey);

But it looks as if the user is not yet logged in at this stage. Can this somehow be forced so that we can access the newly created userid right after the user has clicked the create user button?

Security :: User Details Access In Different Domain

Mar 9, 2010

Im working on an application that has a login section that accepts a username and password. On successful login a userid is returned and encrypted with TripleDesKey. The user details are then stored in a session object. We already have a class library that performs encryption and decryption using a key in the web.config file. I basically want to be able to access the user details of the currently logged in user in a page accessed from the main site that may be in a different domain, but is effectively part of the same site, so I wont have access to the session object from the main site. so basically a user logs in, I have the user details stored in a session object, I also have access to the encrypted userid also in a session object. If a user then clicks a link to another page that is in a different domain, how do I persist the userID?

I suppose I could I tag the encrypted userid to the querystring, but security could be an issue here (even though the id is encrypted, someone could still modify it)

Security :: Detect Multiple User Logging Into The Same Domain In One Browser?

Jul 12, 2010

Two users using the same machine, same browser.

User 1 logs in the domain.
User 1 changes some data without saving it.
User 2 logs in the domain in a separate tab.
User 1 switches back to his tab and saves the data.
User 1 actually saved the data into User 2!!

This is caused by the following mechanism:

Different tabs in the same browser seems to share the same session id. We are storing user auth in cookie and the cookie is shared between tabs (same domain)

Therefore, when User 1 request to save, it is recognized as User 2 since the cookie has been updated to User 2.

So I'm wondering if there's any other methods to prevent this from happening, other than:

1. Use cookieless session so the session is embedded in uri.

2. Always include a hidden field in page to indicate which user owns the page.

Security :: Logon Failure Security Event 534 And Impersonation?

Oct 4, 2010

I have an app that uses impersonation to gain access to a database (on server separate from IIS). The app connects to the database using a trusted connection and seems to be working just fine. However, we get these logon failure events in the security event viewer:


It must have something to do with impersonation because the login failure is for the domain account which my app is impersonating under. But again, the app is working fine so I'm having a hard time figuring out how to stop these logon failures.
