Security :: How To Access Network Share On Domain By Using An AD Account Credentials
Apr 23, 2010I've been researching and I've spent pratically all day on this. Here's my issue. The website uses forms authentication that we authenticate against active directory. I've been attempting to access files we have on a network share and push them down to the user (when they request them) in an http response. I keep getting "Access to the path <unc path> is denied".
Here's the code:
[Code]....
Things I've tried:1) When I add the "Computer" to the permissions of the folder it works and I dont even need to emulate a user (essentially just commenting out this code), but I'm not sure we want to explicitly give the computer access to some of our network shares 2) I've verified it's the correct username and password for the active directory account and that they have permissions on these network shares 3) I've fooled around with the WebProxy class with no luck (as I'm not entirely familiar with it) 4) I've tried impersonating the user by creating a windows token and passing the token as credentials (i've done this with similar websites) with no luck, plus this seemed a bit complicated for something I figured would be relatively easy.Its almost as if, the WebClient class isn't even using the credentials i've passed it.We've got it working now, but only by giving the "Computer" specific permissions on the network shares, which we'd like to avoid.
Security :: Impersonation With IIS And UNC Virtual Path Share
Oct 28, 2010It took me 6 hours to figure this one out and I'm wondering if someone can give me an answer why it has to work this way. I have two PCs, one is a webserver win2k 2003 and the other is the file server running Windows XP. Both PCs are on the same company domain therefore they can see each user. The share folder has NETWORK, NETWORK SERVICE, USERS (which include IIS authenticated users), a LOCAL account, and a specific User (which is me) that is given access to read. In my web application, I call a server.mappath. In IIS6.0, anonymous is disabled so users use integrated Windows Authentication. I can see this by verifiying User.Identity.Name.ToString(); Next, I also check WindowsIdentity.GetCurrent().Name.ToString();. In my first run, I set impersonate to true and thats it. Both User.Identity and both Windows.Identity show: mydomainsmith_B as an example.
When trying to access the UNC virtual path whcih has "Always use the authenticated user's credentials when validating access to the network directory" checked. This means , IIS6.0 will pass mydomainsmith_B credentials to the file server. I get an access denied which is verified by a thrown exception. I go back and check the file server and under the security tabs, I did add myself which shows smith_B under the security and for kicks, I'm also under Share tab.
Next, I try to authenticate using a "LOCAL" account on the file server. The local account is called username/password: temp/temp. So I set web.config to impersonate=true, userName=temp password=temp. Okay, so I go back into IIS 6.0 and for the virtual directory, I go to "Connect As" and set Username and password to: temp/temp and un-check "always use the authenticated user's credential". Finally, i reload the page. This time the page shows me:
User.Identity.Name: mydomainsmith_B
WindowsIdentity.GetCurrent().Name: temp
perfect, so now I'm impersonating temp. I click a button to access the UNC path and boom, it all works. So why doesn't my local PC authenticate ME, as MYSELF, which is on the domain, which is on the same domain. Why do I have to impersonate a local account to the file server? Why can't I just impersonate myself? Also, If I disable impersonation, it becomes NT AUTHORITYNETWORK SERVICE. This service also can't access the UNC path even when I have enabled the same security and same share settings.
Web Forms :: Can Access Network Share Folder With Impersonating
Sep 29, 2010I am stumped. i want my asp.net website to access a network share folder which is located at say, //hero/superman. I can do it manually.
I've done the following:
1. Included <identity impersonate="true" userName="IUSR_TEST" password="test" /> in my web.config.
2. Set anonymous access in IIS 5.1 with username IUSR_TEST and password: test in the account that is used for anonymous access. Checked integrated windows authentication.
3. Created a profile for IUSR_TEST in computer/management/local users and created the password: test for it. It is a member of guest.
4. Created a user account IUSR_TEST for the network share computer. gave it the same username and password.
4. On the network share computer, I've enabled access for the following people: ASPNET, NETWORK SERVICE, and IUSR_TEST.. all with full potential (for now) for the directory path in question //hero/superman which is really located on: c:herosuperman. I've given it full access.
But when I StreamReader fs = File.OpenText(Server.MapPath(@"\herosuperman est.txt"); I get the error "UnauthorizedAccess Exception". Access to the path \herosuperman est.txt is denied.
So what did I miss, what am I doing wrong. The key thing here are:
the webserver is on a domain. the network share computer is NOT on a domain, it is on it's own workgroup. This workgroup, lets just say is called "villains". So if I have to manually map the network drive to access the files, I must type: /villains/IUSR_Test and password: test to be able to map it on my webserver local computer.
MVC :: Error In Opening A Pdf File On Network Share / Access To The Path Is Denied
Nov 23, 2010I'm not able to open the file when I click on the link on page in MVC. I get the following message. I've added the impersonation in the code. I'm able to delete and save the file.
Access to the path '\servernamefolder1folder2folder3foder4filename.pdf' is denied. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.UnauthorizedAccessException: Access to the path '......same as above....' is denied.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

Security :: Accessing Network Share Via UNC / Virtual Directory ?
Oct 27, 2010A month ago I got everything working but now my code has changed and my server may have been misconfigured.
Basically, I'm running IIS 6.0 and Win2k 2003. The webserver will map a network path UNC share at: //wave/test
Also, I have webconfig set up to do: impersonate = true (no username/password defined)
the path //wave/test is another computer that runs Windows XP. Wave is the computer name, test is the folder name. So C: est is the folder to access. The current permissions under C: est on the file server is: Administrator, IUSR_WEB (read-only) and "Wave_user" (read-only)
Back in WinServer 2003, i've added a virtual directory and mapped to \wave est and applied a local username/password for Wave_user. I am able to see/browse all the files in IIS 6.0 and see the files/folders. I call the virtual directory alias: "Waves". Inside Authentication method for this virtual directory, i applied Wave_user and the local password of the local file-server PC , and checked enable anonymous access w/ integrated windows authentication.
Also, back in virtual directory, I set "Connect As" to wave est as username and password as the local password.
When I access the webapplication, using my current local PC credential, and try to access the network share, which in C# is the command: server.mappath@("wave"... i get a Server Error 401. in the browser.

Security :: No Impersonation - But Wrong Account Being Used To Access Files?
Aug 2, 2010I run a simple .aspx website on a Windows Server 2008 machine.There is no impersonation, and System.Security.Principal.WindowsIdentity.GetCurrent().Name returns NT AUTHORITYNETWORK SERVICE, which it the account which the application pool runs.I tried to test the security of the application and server by removing file permissions to the .aspx files. I was greatly worried when the website continued to run without problem (it should not have been able to read the .aspx files).By turning on file level auditing, I discovered that the .aspx files were being read by the machine$ account (if the machine is called Serv1, then the files would be read by the Serv1$ account, which seems to have access to all files on the local machine).Is this a security breach or is this behaviour by design ?

View 2 RepliesSecurity :: Impersonation Error / .NET User Account Has To Be Given Permissions To Access The Folder
Jun 18, 2010I wrote an asp.net 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 asp.net program would have the same credentials as myself because server-side code. Turns out I am wrong. When I go to use the asp.net 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 asp.net 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:
[Code]....
(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'.

View 4 RepliesAnonymous User Cannot Print To A Network Printer?
May 17, 2010I have an ASP.NET application where user is Anonymous when he connects to website. Also I have a printing server inside network. I want to let this user to print to the network printer.
In order to print I have to use File.Copy command. When I do this I get "Access denied". So I tried to impersonate the user with credentials of user that is inside domain and has the rights to print to that specific printer.
The problem is this user has to be Administrator, and I cannot let him be the Administrator. When this user is not Administrator then the printing is not working ("Access denied").
I tried to use Network Credentials but I don't know how to set credentials to command File.Copy. This command doesn't have any extensions or overloading for credentials.
Security :: Webservice Is Denied Access To Network Folder
May 27, 2010I wrote a web service sometime back, and uploaded to one of our network Server's IIS. The webservice needs to access a network folder, which was working perfectly fine till a month ago. Now, when we use the webservice in our .Net application, it fails with the exception message "Access to the path '\<networkMachine ><Folder >' was denied" (may be some group policies changed). But when I run the webservice from my local machine's Visual Studio debugger, it can access that folder. What could be different on the server's IIS w.r.t. my service? Why was it able to access the network folder before but not now? Please note that I can manually access that shared network folder from my machine, and also when I remote desktop to that <networkMachine> from windows explorer.
I saw in the task manager on the server that the IIS process w3wp.exe is running under 'NETWORK SERVICE' account. Though the network folder is not shared specifically with this account, but that has given read & execute access to 'Everyone'. Then what is the problem that it cannot access the folder. By accessing I mean creating a 'DirectoryInfo' object of the path '\<networkMachine ><Folder >' and reading all the subfolders -

WCF / ASMX :: How To Create A Folder On A Network Share
Mar 7, 2011I have a web application that uses Windows Authentication, not forms, and has identity impersonate = true.
From an .aspx page, the following code can create a folder on a network share successfully but fails in my .asmx page.
dirPolicyFolder.CreateDirectory(ConfigurationManager.AppSettings("PolicyApplicationsPath") & strFolderName
I have confirmed that the same user is logged in both examples, permissions on the parent folder are set correctly, and the logged user has propper right to do this.
If I change the path to a local one, the asmx page can create the folder.Why would this fail when running in the .asmx page?
Security :: Access Denied For Logged User (anonymous User Is Fine)
Jan 7, 2011I 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.
Security - Accessing Network Folder With Network Service Account
Aug 17, 2010My ASP.NET MVC 2 application runs under built-in local NETWORK SERVICE account. I want to set up access permissions for the folder which resides in another computer, but in the same domain. I located that folder right-clicked to open its properties form, clicked to Security tab and pressed Add button which displayed Add user form with correct domain name in the location field. I referred to the account with following syntax:
<domain name><server name>$
because I learned that NETWORK SERVICE account uses machine account when connected to other computers in the domain. However, the system couldn't find the account, so refuses to add the account. Without the domain name it adds a user, but that user seems to be local user, not web server's NETWORK SERVICE account. What am I doing wrong?
By the way, the above syntax worked when I created login for the sql server which is different computer from the web server.
Security :: Logon Failure Security Event 534 And Impersonation?

IIS 7.5, .NET, Impersonation, And Access To C:WindowsTemp?
Jun 7, 2010Summary: One of our web applications requires write access to C:WindowsTemp. However, no matter how much I weaken the NTFS permission, procmon shows ACCESS DENIED.Background (which might or might not be relevant for the problem): We are using OLEDB to access an MS Access database (which is located outside of C:WindowsTemp). Unfortunately, this OLEDB driver requires write access to the user profile's TEMP directory (which happens to be C:WindowsTemp when running under IIS 7.5), otherwise the dreaded "Unspecified Error" OleDbException is thrown.
