Security :: Get Current Windows Logon User?
Mar 22, 2010
I have created an intranet site in win 2008 server. Enabled Windows Authentication and disabled Anonymous. I want to get AD logon username(current win logon user).I used HttpContext.Current.User.Identity.Name and also tried User.Identity.NameI am accessing the site from client machine. I am not getting the client's logon user instead getting the server's logon user. But I want client's logon user only.I just want to get username. I dont need any login screens or bla blaWhen I run in my development system(XP), its working fine.
When I deploy to windows 2008 server, I am getting problem(Getting only the server's logon user instead of getting the client's logon user).So, problem in the server settings. So, any settings I need to set to get this worked?I enabled Windows Authentication for my site in IIS management window. Disabled Anonymous authentication.

I'm using forms authentication in my application but i want to get the active directory domain anme and user name of the logon user. is that possible. The IIS Directory security settings are Anonymous Access allowed and Integrated windows authentication ticked. I tried the following but to no avail
Request.LogonUserIdentity.Name (this is returning the machine name and user name used for anonymous access)
System.Security.Principal.WindowsIdentity.GetCurrent().Name -> returning NT AUTHORITYNETWORK SERVICE

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 have created an Intranet site using windows authentication based on role membership. It is working great. My Web.config is shown below.
<authentication mode="Windows" />
<roleManager enabled="true" defaultProvider="AspNetWindowsTokenRoleProvider" />
<authorization>
<allow roles="D820Developers, D820IT, D820Staff, D820Providers, D820Supervisors, D820Directors, D820Interns" />
<deny users="?"/>
</authorization>
Now my user wants the capability of being able to login to the intranet site as another user. For example, IT guy needs to login on a user's system to set some data.
I have created a standard MS Login Page. However when I try to login on the page I get the message
Your login attempt was not successful. Please try again
I do not have a database (aspnetdb.mdf) storing user information but login against the active directory. Can you use the login form with windows authentication without a database?

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 ?

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:
[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.

I'm in the middle of moving a web application from IIS6 to IIS7. I've enabled "Windows Authentication" and added <deny users="?" /> to the authorization section of my web.config file. When the app was running on IIS6 my users where able to access the web app without logging in because their windows login was automatically recognized. This does not seem to be the case in II7. I can not get a value for "Current.User.Identity.Name" in my ASP.Net code.

I am trying to make a Contact form exclusive for Members. So as my first field (ID=username) I would like some VB script so that when the page loads it can identify the user that is accessing the page and display it in a read-only text ready for submission by email (with the email address and text area, don't worry about these because I know how to add these).
(here is my Contact us page code, nothing special but I'll give you it just in case)

The thing is that I'm creating a community fanpage, I have the membership database installed and I have created user profiles for the users, and it works fine. The thing I can't seem to find anywhere is how to capture the current logged on users username and save is as the author of a post in the database. Like right now, I'm writing a post, and when I click Post it will say it's written by Jeanz91 because I'm the user who's logged in. How do I get my site to do that?

I create two pages, the first one is the login page with user name and password textboxes - (not asp login control) , when clicking login button I check the login authentication, if it is true redirect to default page. in the default page if !IsCallBack then i check httpcontext.current.user.identity.isauthenticated
if it is false i redirect the user to the login page. but my problem is that the httpcontext.current.user.identity.isauthenticated is always false.
Below the section of authentication in web config

I was/am struggling with security for my first MVC applicaiton. It worked out great for me, but not for my users. I wanted to use Windows Authentication (and I seem to have that working). But when I was still trying to implement it, I was on one of our users computers where they were logged in. I navigated to the main Index page and used the supplied MVC login link and *MY* credentials. So now every time that user navigates to that page, it logs her in as me. We are using IE8, I have deleted all the cookies, passwords, forms information I can fine through Tools|Internet Options|Tool|Content|AutoComplete.

I am having a problem with security in a web application I am building using Visual Web Developer 2008. I am using Forms Authentication:
<authentication mode="Forms">
<forms name=".MYAUTH" timeout="20" enableCrossAppRedirects="true" />
</authentication>
And a SQL Server database with ASP.NET Membership and Roles. I am using the LoginView control with the AnonymousTemplate and LoggedInTemplate to manage the user's interaction with logging in and out. The problem I am having is that I am authenticating the user against the database:
If Membership.ValidateUser(_userName, _txtLoginPass.Text)
Then returns True and:
FormsAuthentication.SetAuthCookie(_userName, False)
sets the cookie correctly:
FormsAuthentication.Decrypt(FormsAuthentication.GetAuthCookie(_userName, False).Values(0))
{System.Web.Security.FormsAuthenticationTicket} CookiePath: "/"
Expiration: #1/21/2010 1:42:27 PM#
Expired: False
IsPersistent: False
IssueDate: #1/21/2010 1:22:27 PM#
Name: "jaymo "
UserData: ""
Version: 2
but when I check
HttpContext.Current.User.Identity.IsAuthenticated it always returns False.
If done this before and it worked fine. I cannot find any mistake I might have made or where something might have changed between ASP.NET 2.0 and 3.5.

We have an SharePoint site no login (anonymous) with a search module using AJAX. Now the users complains that the module isn't working. When I check the code (not developed by me), I find that the code only runs if "HttpContext.Current.User.Identity.IsAuthenticated=true". Could that ever return true on an anonymous site?
