Does ADO In An Web App Always Use The IIS Service Account To Connect To SQL Server
Mar 8, 2011
I have an ASP.NET web app where I use an ado sql connection to connect to a database on a SQL Server. The ado connection string is provided with a user login that has sufficient rights to read/write to the database. I originally pushed out the web app in its own IIS web site, using its own application pool and everything worked fine.
However, I am now trying to include the web app under an already existing web site. Everything seemed to work fine until I tried any functionality that called for an INSERT or UPDATE to the database. It turns out the user connecting to the DB didn't have sufficient permissions. Finding this strange, I did some research and found a forum post that suggested the IIS Web Site service account needed read/write permissions in the SQL database in order for an app to perform INSERT/UPDATE. Is this true?
I tested it out, and yes, indeed it worked, only with the Application Pool Identity account. The deatails of my scenario are as follows:
The web app's first IIS Web Site had an application pool Identity that ran under NETWORK SERVICE, which already had a login for SQL SERVER The already existing web site's application pool Identity runs under a domain account. This site already runs another web app that connects to the same database using LINQ (developed by someone else). I am relatively new to web development and am more familiar with ADO, so that is the route I chose.The domain account mentioned above formerly had no SQL Server login/user mapping. I set it up as a dbowner, and viola, the new web app worked under the existing web site.
While I found a way for it to work, we would rather not create a SQL login for this Identity account. We want the login provided in the web app's ADO SqlConnection to be the one to actually connect, because isn't that the point of it?
In our database we have an SQL server account that has the correct roles to access some of the databases.All of our PC and Servers are in domain using Windows Account. Now there is ASP.NET web application, we want the users in the domain to browser some data in the sql server. But we do not want to grant direct permission to every person, so is it possible to connect to sql server and run some T-SQL without granting permission to users using one specify account?
I have an ASP.Net app, that runs using windows authentication. The connection to the SQL Server is usually done by creating a sql server account and using that in the connection string.
However, in this specific very restrictive hosting environment, we have been asked to use a specific WINDOWS/active directory account to connect to the SQL Server.
note it is not the windows credentials of the user of the website, we need to connect to the SQL server with - it is one specific windows/AD account.
I have a web service in which i am making connection to the database to get data..now i want that the app pool account should be used to make the connection and not the current user's credentials..can somebody tell me step by step what changes do i need to make like setting impersonation=true etc.
when I call the web service from the windows service. But I can visit this web service through IE and I also wrote another console application to call the web service and it works fine, too.
The exception infomation is below:
A socket operation was attempted to an unreachable network 127.0.0.1:8888
I try many methods, like turn off the firewall and anti-virus software, set the web services proxy property to null. but still cannot solve this issue.
Is it possible to run a web service as a particular user/service account in the same way a Windows service can?I have a service account used for connecting to the DB and want to run the webservice under this account as the users using the webservice won't have DB access.The way I see to do it is to include the Impersonate option in the Web.config file, but is there any better way to do this?
Can a user connect to my web site using an Orkut account ? Just like Google Friend Connect or Facebook, but with Orkut.
The idea is, the user goes to my web site, I have a "Connect using Orkut" button there, on click takes him to the Orkut login page, once s/he logins and grants access to my app, get's redirected to my web site with the Orkut ID as a parameter. The same procedure that works for Google Friend Connect and also Facebook Connect....
I haven't seen an example of this with Orkut. Can it be done ? Is there an Orkut Connect or similar ?
A sample in c# would be excellent, but I would be happy with a sample in any language.
In some sites specially online shops, users can pay from thier bank account or cridit card.how can we implement online payment. what is the proccess of online payment? is there any API or Dll for this.
I have created a web service that authenticates with username and password, works fine. Basically this one, http://msdn.microsoft.com/en-us/library/ff649647.aspx
Now I also want to connect to this web service using client certificates, works fine http://msdn.microsoft.com/en-us/library/cc948997.aspx
But I would like to when authenticated via client certificates, connect that certificate to a user in the membership database. So that I can use Roles.IsUserInRole(...) and such.
I thought that, well if I implement a Custom certificate Validator http://msdn.microsoft.com/en-us/library/ms733806.aspx then I could check for example subject and map that against a created username in the membership database.
But in the class X509CertificateValidator public override void Validate(X509Certificate2 certificate) I don't have the same ability as when the user is authenticated like
app.Context.User = new GenericPrincipal(new GenericIdentity(username, "Membership Provider"),roles); within public override void Validate(X509Certificate2 certificate)
and if that is not possible, can this be solved differently? Bottom line, how do I connect a client certificate to a user account in the membership database. Is there a MSDN article on how to do this?
I have a web application. This application needs to perform a search on folders located on 2 different machines. I can use impersonation for this. But -
a. I don't want to use network service account b. I want to impersonate just the search part of the code. c. Specifying encrypted user name / password in web.config is one option. But this would be the last option.
Can I use a custom service account for the application pool for this? If yes, then how to impersonate a specific part of code using this?
I am looking for a code which does authentication using service account username and password. I mean username and password which has permission to access the active directory and then authenticate the actual username and password provided by end-user. Googled everywhere but could not find any suitable code.
First, I felt I had a clear understanding of how the Network Service account work. It is the default account ASP.Net runs under and has very limited access. I have verified in the Application Pool that ASP.Net is running under the Network Service Account. I have a UNC file share that is located on another server, let us say "\myservermyfiles". I have logged on to "MyServer" and right-clicked on the shared folder "myfiles" and just for the sake of testing, went to the Shared Tab->Permissions and added the Network Service account and gave it "change and read" access. I then went to the Security Tab, added the Network Service account and gave it all permissions. For some reason, I am still getting an "access denied" exception. I know impersonation is an option at some point, but I would really like to know why my ASP.Net application cannot copy a file to this share just for my own personal understanding given the fact that I gave the Network Service account the proper access. Like always, I will continue to research.
I'm new to WCF web services never done anything with them before and I'm being asked to create a page to connect to a WCF web service I have no idea where to start and I've searched the internet with no success. Does anybody have an example of an asp.net page connecting to a WCF web service? I've set up the WCF web service on my server but do not have a clue on how to actually connect or query it to get my XML data back.
The WCF web service is set up as it's own URL and only has 2 files within the root one being the web.config. I somehow need to query this URL and get some XML data back from it.
I just finished setting up the environment for an ASP based web app on a Windows Server 2003 machine, IIS 6.0, ASP.NET 4.0., with custom service account.This is not a domain based setup, so I have created mirrored logins on both servers (WEB server and SQL Server 2005). Everything works just fine except the fact that every time I try to browse the main page, a login pop-up window will request login password confirmation. I tried many things so far. Making sure IIS is in NTLM Authentication mode, checking access rights for the local login I created, workarounds I found on MSDN, etc.
This happens only if I change the Directory Security to not allow anonymous access (Authenticated Access - Integrated Windows authentication only). If I keep both, or only anonymous, everything works fine.Is this the intended behavior? Am I doing something wrong here?I already tried everything I found on MSDN regarding these types of errors. If I do not enter a password for three times in a row, the error says "HTTP Error 401.1 - Unauthorized - Access is denied due to invalid credential."
Public Function HelloWorld() As String Dim orgcon As New OLEDBConnection("Provider=Microsoft.jet.oledb.4.0;data source=c:dataDB.MDB") Dim OrgDA As New OleDbDataAdapter("select * from organization order by orgname", orgcon) Dim Orgds As New System.Data.DataSet OrgDA.Fill(Orgds, "Organization") Dim hwstring As String hwstring = orgds.tables(0).rows(0).item(3).tostring Return hwstring End Function
The flash just gives me an error that there was an error opening the web service. For some reason I can´t debug it in vwd.
I have a website project in VS 2005 using VB. From it I connect to a web service that sends an email. This was running just fine until my department moved locations (and along with it the server hosting the service). Now my project can't connect to the service. I deleted and added the web reference again and VS found it and it's methods just fine. I can browse to the service in my browser successfully.
The emails are no longer getting sent and there is no error raised. I tried debugging and when I step into the call to the service then I get the error "Unable to automatically step into the server. Connecting to the server machine '[mywebservice]' failed. ...". I do not need to debug that service; I was only confirming that the project wasn't connecting.
When the project is loaded onto our virtual server for testing it runs as expected.
How can I get my project to connect to the web service from my localhost as it was before the machine was moved?
I am looking to incorporate web service into my application but am running into a problem. The following line of code in FwkComm.js document generates the following error: Microsoft JScript runtime error: 'FwkService' is undefined.
Every month I have to email out links to demo music tracks that I make. I have like 30 labels and it takes me ages to write out an email to each one. I dont want to purchase my own domain name yet so is there a free email provider that I can sign up to that will allow me to use .net library to automatically send out messages?
I have an existing windows .net application that has an access database as the backend.
I want to place the access database on a web server and it was suggested that I create a web service in order to communicate with the database.
I've been looking at some tutorials but am still confused about the basic config needed. Here's some questions I have:
1) Does the web service need to be created inside my current project by right clicking on the solution and choosing to add a new web site...and then selecting web service?
2) If it's set up like this, what files do I place onto the web server?
3) Where does the database reside? Do I need to place the database inside the web server that I create?
4) My current project has existing sql that gets data and I'm uncertain how to re-write in order to retreive the data. e.g. which part goes into the client and which part goes to web service pages? here's an example of a procedure that currently exists...I'm getting data to populate a dropdown:
I've got an ASP.NET website, and its connecting to a database I've created on SQL Server 2k8 and I'm using windows integrated security on my connection string between asp.net and SQL Server. What account should I give permissions to my database inside SQL Server? Should I give NT AUTHORITYNETWORK SERVICE permission to my database? Right now, I right clicked the network service account, and went to properties, and then I checked my database under "users mapped to this login:" and then in the "database role membership for" diaglogue I then selected public and db_owner. Is that right?
I have created an asp.net web application on windows server 2008. I have created a website in IIS 7 with an application pool. The application pool has the identity "NETWORKSERVICE". I have a web reference in my application with a certificate.
When I create a new web application and add the code below and add the web reference, and run the web application from the solution (and not from a website in IIS), the web service works fine. I think the local administrator has permissions and the network service account not.
public static PartsService MyCompanyPartsService { get { if (_partsService != null) return _partsService; _partsService = new PartsService(); _partsService.PreAuthenticate = true;
My 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.
Code: Dim objstrSupUser As String = "" 'Load the user from the membership provider Dim strUserName As String = ctlLogin.UserName If ctlLogin.UserName.IndexOf("(") > 0 Then objstrSupUser = Regex.Match(strUserName, "(([^)]*))").Groups(1).Value
