Security :: Login User Into Windows From The Service
Nov 22, 2010
Is it possible to remotly login into Windows using ASP? What I'm trying to accomplish is, that I could remotly call a ASP page on my server (Apache on Win Vista) that logs in a user on that system. For example remotly I start a Wake-On-Lan to start the computer (server). It boots up to the user login screen where I would have to enter my password to login to the desktop. Because the service is already running at that time, I would like to open a ASP page from my client that I could pass the windows user/password and the ASP-service would login the user on the server machine.

On my Intranet page I want to be able to recognize the user by their Windows Domain login. I am using VB 2010 and ASP. I have several VB books but none of them cover this. If it isn't too much to ask could someone show me the way. I have a strong SYS ADMIN background and am pretty sure this will involve LDAP but that is about as far as I am.

I am using Login control and validationg the user against SQL datasource. below is the code:
Protected
Sub Login1_Authenticate(ByVal sender
As
Object,
ByVal e
As System.Web.UI.WebControls.AuthenticateEventArgs)
Handles Login1.Authenticate
e.Authenticated = IsValidUser()If IsValidUser() =
True
Then
Response.Redirect("Orders.aspx")End
If
End
Sub
Here is IsValidUser
Private Function IsValidUser() As Boolean
Try
Dim sql As String = String.Empty
Dim RecCount As Integer = 0
sql = "Select count(*) from UserLogins where UserName='" & clsDB.RemoveQuote(Me.Login1.UserName.Trim) & "'"
sql = sql & " AND UserPass='" & Me.Login1.Password.Trim & "'"
RecCount = clsDB.ExeScalar(sql)
'If Invalid ==> 0 means no record is being returned by Query
If RecCount = 0 Then
IsValidUser = False
'MessageBox.Show("Invalid User Name/Password.", "Invalid", MessageBoxButtons.OK, MessageBoxIcon.Stop)
Exit Function
End If
If RecCount = 1 Then
IsValidUser = True
Exit Function
End If
'Error handler
Catch ex As Exception
End Try
End Function
Here comes the problem validation code is working fine and it validates the user and redirects the user to the "Order.aspx" page
For example: I type
Login Name: Nashy
Password: 1234
Order.aspx page has a textbox which supposed to display the current user login name and i am usiong the following code for that
textbox1.text=Web.HttpContext.Current.User.Identity.Name.tostring()
when i test it on my local PC it shows the current user like this DOMAIN ashyMastrew.. what i want that the textbox should disply "nashy" not my current windows login name. and when i deploy it to the server and access it from other pc textbox does not show anything.

I've set up a system with forms based authentication and using the asp:Login control. When I put in an invalid password I get the approriate invalid password message. However when I put in a valid password, it does nothing...just returns to the login page again. I'm triple checked the login info. There is no error message, and the invalid attempts counter doesn't increment. When I put a break point in the Login_LoggedIn event of the Login form, it hits it, but User.Identity.IsAuthenticated is false. I'm not 100% sure it should be true at this point, as I'm pretty new to .NET but it seems kind of odd.
My user database is stored in a sqlserver 2005 db that already existed. I've added a new connection for it.In the authorization I have
<authorization>deny
users="?"/><authorization>

I need to create an application with Forms Authentication and/or Windows Authentication. If the application is set to use mixed authentication (Forms + Windows Auth) and the user don't have a Windows user account, the login will fail and he must be redirected to a forms login page. How can I do this?
Are there any different way to provide mixed authentication?

I am writing two ASP.NET apps. One is a web service that provides xml data and the other is a web client that will use the service to display and manipulate data. I would like for the web service to do the membership authentication and authorization. Is there any way to simply point the login controls in my client application to the web service instead of to a database. I assume I would have to provide the necesarry methods in my web service interface, which would then use the membership provider database I created and pass the results back through to the client.
Is this possible? I have seen many articles on security provisioin from a web service but none has really been what I am looking for. I was hoping that, since my service and my client are both written in ASP.NET, there might be some built functionality that would benefit me.

I've a Gmail account, assume that me@gmail.com. Now I want to login (as admin) in my website through this account. I know I can use OpenID etc. for that purpose but I want to limit it for just me only. Can I do this? I don't let anyone else to know which service I used to login and what is my address and etc. (Note: My website contains just one and only one login form, for just me, only!)

I have to invoke SSIS packages from web service in the most secure way. I think that windows authentication will be secure but i am not sure. I do not have much knowledge about how to achieve this and the information on the internet is very distributed.

In the IIS, it shows that the web app (i'm using) is using an application pool that uses NETWORK SERVICE account for identity. But when I debug/run my web app, User.Identity.Name shows that my windows user login instead. I checked my web.config file, and it does not have Impersonate enabled. In fact, I set it to false, and it still shows the same.

I was wondering what the following error means: Login Failed. The Login Is From An Untrusted Domain And Cannot Be Used With Windows Authentication. Initially, when my application was much simpler, I had no permissions and roles and my authentication mode was set to "windows". Afterwards, however, I added authorization, changed the authentication mode to "Forms" and ever since, when I try to login, I get the error above.

I have a web application that uses a SQL database which contains all the standard asp membership tables.Within my Web application I use the standard asp.net membersip logic for adding new users, roles, etc...The point here is I dont use any custom providers for anything.Now on that same machine that is hosting my web application I am writing a Windows service in c# .net.As part of one of the method calls to the windows service application I was curious if I would be able to use any type of membership classes that would connect to my existing database and perform the same functionality as does the ASP.NET membership classes.

I've created a page to add users, using the CreateUserWizard, I use the Login Control to login.
I have setup the config file to use my SQL server, not express
<remove name="LocalSqlServer"/>
<add name="LocalSqlServer" connectionString="Data Source=xxxx.xxxx.xxxx.xxxx;Initial Catalog=aspnetdb;Persist Security Info=True;User ID=xxxx;Password=xxxxxx" providerName="System.Data.SqlClient" />
I go to the create user page, add a user.
I can SEE the user on the database using Server Management Studio...
I go to signon and get "Your login attempt was not successful. Please try again."
I have not customized the login control in any way. (OR the createuserwizard)
HOW can I tell where the Login tool is going to get userid and password info?
How can I tell if it is not finding the user or the password does not match?

I am using Visual web Developer 2010 Express.
I want to create a small intranet web site with a login page that will authenticate against groiups of users in Active Directory. So for example if someone in Group A logs in they can get to web page X and if someone from Group B logs on they can get to web page Y. Is it possible to do this with the login controls without writing code? I thought it would be a fairly standard thing to do.
