Security :: Logon Failure Security Event 534 And Impersonation?
Oct 4, 2010I 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:
[Code]....
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.

View 3 RepliesSecurity :: .NET Impersonation / How To Do The DB Connection
Mar 13, 2011We are in the process of building ASP.NET windows auth application. Where user need to interact with other internal system using the same single sign on. To interact application DB the system relies on App Pool account, for this we are every time doing the imporsanation to before every DB call. We can not have all useres added to DB, or create an SQL account. Which requires password and user to store in Web Config. We can encrypt it again you encrypt with what and etc ..So we have one windows account wihich same windows account used for our app pool as well.
I would like to know from the team is what is the best way to do the DB connection in this case?What is the implcations if we imporsanate the DB calls based on the app pool account ? Is it a best practice? I have read it creates its own thred and stuff, Do we need to worry ?
Security :: Impersonation In SharePoint?
Apr 13, 2010I noticed impersonation is turned on by default in MOSS web configs. I tried disabling it but the web app returns an error. So my question, is it possible to disable impersonation in MOSS? If it is possible are there any special considerations I should be aware of?
If you're interested in why I need to do this...I need to have a custom web part (developed with SmartPart) talk to a separate SQL server using the application pool rather than the current user (Kerberos is enabled). If I set the authentication mode to NTLM I get NTAuthority/ANonymous login errors from my SQL connection. If I turn Kerberos on, the currently logged in user's credentials are passed. If I hard code the user id and password in the connection string it seems to ignore it and default to whichever security model is in place (NTLM or Kerberos).

Dec 27, 2010I am trying to use impersonation on an IIS server while I access Active Directory data. The following code works fine on the localmachine but when I put this same code on an IIS server I get an error: System.DirectoryServices.DirectoryServicesCOMException: An operations error occurred.
If I remove the top 4 lines and add my ID and passcode to the DirectoryEntry, everything works fine. I would prefer to not have my id and passcode anywhere on the web. Any ideas on how to fix this? Dim impersonationContext As System.Security.Principal.WindowsImpersonationContext
Security :: .NET Impersonation In IIS 6 Is Not Working?
Sep 2, 2010I am using impersonation in my ASP.NET application to access network resources. It works fine when I run on my computer, however when I setup the site on IIS6, it does not work. Is there some extra configuration, I need make in IIS for it?1. I created an account "TestUser" with the privilege as "act as operating system" on a server that has the resources which I want to access.2. The impersonation works fine on my computer, when I run from visual studio. My computer is on the network under same domain where the "TestUser" is created.

Security :: Impersonation With Forms Authentication?
Mar 1, 2011I have been looking for code samples on how to do impersation with forms authentication for the current logged on user. I have found samples on the internet and this site and most seem to refer to windows authentication not forms. I am wanting to run specific blocks of code under the current user's credentials to access lists of files on servers on the internal network and display them in the page.I found this article on MSN for using impersonation in various ways, http://support.microsoft.com/kb/306158 and I was able to use the section of code where it describes how to Impersonate a Specific User in Code. This works quite well with forms authentication but requires a service account in AD with login and password. One the same page is a sample of how to impersonate the authenticated user in code, but this only seems to work with windows authentication. As have all other samples I could find, such as the article here,http://www.codedigest.com/codedigest/9-identity-impersonate-at-code-level-in-asp-net.aspx. But trying those with forms authentication results in the error "Unable to cast object of ype 'System.Security.Principal.GenericIdentity' to type 'System.Security.Principal.WindowsIdentity'" Since there is no windows identity with forms authentication.Can anyone point to an article that describes how to do impersonation with forms authentication at the code level?

View 2 RepliesSecurity :: 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.
Security :: Trying To Set Up Impersonation For A Vrtual Directory In One Of My Sites
Jan 10, 2011 I am trying to set up impersonation for a vrtual directory in one of my sites. If I set the impersonation to
<identity impersonate="true" userName="Domainuser" password="password"/>
it works perfectly.However, if I set the impersonation to
<identity impersonate="true"/>
and then go into the Properties of the Virtual Directory and set the Network Directory to Connect As my domain user it does not work.
Shouldn't the impersonation look at this user account? Or is it looking at my Anonymous Access account?
Also, do I need Windows authentication enabled for this to work?
Security :: Impersonation Settings On IIS To Enable System
Dec 9, 2010I have a Win7 Pro laptop that I do my development on and it is in Domain1.I have a Win2003 server that has a shared folder on it and it is in Domain2. I have an impersonation routine in my code that allows IO to occur between my laptop and the server, it works.When I move the code to my Win2003 hosted servers the impersonation does not authenticate to the shared folder.Is there some kind of domain policy, IIS or Windows 2003 setting that prevents impersonation from occurring (there no impersonation in my web.config, only in code)? I saw in the security faq something about running the -ga command in order to grant the
permissions. What is this referring to exactly?

View 5 RepliesSecurity :: 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 3 RepliesSecurity :: Application Within A Sharepoint Web Part Using Impersonation But Need Windows Identity
May 12, 2010I currently have a client with a SharePoint site that wants to incorporate an (already written) ASP.NET application within a webpart in the SharePoint site. The ASP.net application currently uses an IIS impersonation account to connect to the SQL database.
Some added functionality the client is requesting would require me to grab the user's windows login identity to use the SharePoint UserProfileWebService to query the PropertyPages for that specific user. Because the (already written) ASP.NET application uses impersonation, when I grab the WindowsIdentity.GetCurrent().Name, I get the impersonation account and not the actual user's account.
Is there a way to keep the current setup (impersonation account on IIS to connect to SQL) and still grab the logged in user's credentials? Or would a better way about this be to change IIS to consume the Windows Identity of the logged in user and encrypt the connection string in the web.config?
