Security :: How To Get Windows Domain Name And Username

Jan 19, 2011

My intranet web application uses Forms Authentication. How do i get the Active directory domain nameusername of the logged in user. The IIS directory security settings for the app are:

Anonymous User Access : Ticked
Integrated Windows Authentication : Ticked

I tried using the following but to no avail

System.Security.Principal.WindowsIdentity.GetCurrent().Name ----> returns NT AUTHORITYNETWORK SERVICE
Request.LogonUserIdentity.Name -----> returns The username used for anonymous access

ineed to pass this information to an external application for the current user to gain access to the system. Can i untick Anonymous user access in IIS and continue using forms authentication? what are the other options.

Security :: Getting Windows Username Using Windows Authentication?

Sep 3, 2010

I am developing one intranet website. Being an intranet application, one of the requirement is to have a single sign on feature.

It means that the windows PC username (i.e the "ctrl + alt + delete" username) is going to be the username for the system.

How do i fetch that username?

I tried the following two ways which are working in debug mode but not on live site.

System.Security.Principal.IPrincipal user = System.Web.HttpContext.Current.User;
Response.Write(user.Identity.Name);
&
Response.Write(Request.ServerVariables["AUTH_USER"].ToString());

Both the above method works when i run the page from visual studio.

However when i run the page from IIS or any other server, it gives me a blank value

Security :: Obtain Domain Username Without Requiring Authentication?

Oct 6, 2010

I'm bangin' my head against the wall here. I'm not even sure what I want to do is possible.
I have developed an ASP.NET app that will only be run on my local network (which incorporates a Windows Domain). It's running on IIS 7.5.I want to do this:

[Code]....

My problem is this: If I don't turn off Anonymous Authentication and ASP.NET Impersonation, I don't get the results I'm looking for. (if Anonymous is allowed, I get an empty string returned for username, and if ASP.NET impersonation is allowed, then "username" is always whatever account is associated with impersonation, like "Network Service"). If I turn those off and then turn Windows Authentication on, it works, but only after a dialog box presents itself asking for the Windows Credentials.

What I'm trying to do is NOT require the users to log in. Since they've already logged into the domain when they signed on their computer, I'd like to just allow them access to the ASP.NET application I've written, and identify who they are (based on their previous Windows login) using the line of code above. I don't need them to re-authenticate, because they're already authenticated from their domain login.I can't figure out what I'm doing wrong, or how to accomplish this. It seems the closest I've gotten to what I want so far, is to turn off all authentication EXCEPT for Windows Authentication. It works then, but only if the user first types in his/her username and password again in a dialog box. Is there any way to avoid having them type in their username and password again, but still be able to identify their domain username?

Obtaining The SecurityIdentifier (SID) From Just A Domain Username (c#)?

Jan 26, 2011

I wish to obtain the domain SID from a user account that has been used to access my web page, but...

In some instances, you dont have access to the HttpContext object to call HttpContext.Current.Request.LogonUserIdentity.User.Value

All the static function is able to accept is a user-name as a string, and a domain-name as a string.

If the domain is left blank, it is amused that the user account name is within the same domain as the IIS server that the process is executing upon. :/

Security :: Login Failed - "The Login Is From An Untrusted Domain And Cannot Be Used With Windows Authentication"

Feb 5, 2011

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.

Security :: Unable To Log In On Domain Which Redirects To Another Domain?

Jul 23, 2010

I have a domain: http://www.mydomain.com. This domain is redirected to http://mydomain.anotherDomain.com.

I user forms authorization, so when the user navigates to Default.aspx he is redirected to Login.aspx. Pretty standard stuff.

On FireFox the user can log in on both on http://www.mydomain.com and http://mydomain.anotherDomain.com.

But with Explorer http://www.mydomain.com doesn't work. I only get the Login.aspx page.

Can it have anything to do with that on http://www.mydomain.com I can't see the filename ('Default.aspx', 'Login.aspx')? How can I enable so the filename is included in the redirected domain?

Security :: How To Set IIS To Handle Both Domain And Non-domain Users

Jan 27, 2011

I have an intranet web application. There are 2 user groups, group A belongs to the domain and group B does not. If I set the IIS to enable anonymous access, Request.ServerVariables("LOGON_USER") always return nothing. If I disable anonymous access and set Integrated Windows authenication, a Windows login prompt will come up if group B's users want to access the website.

How can I setup IIS so that when domain user access the website, it will direct to the main page with Session("user_name") = Request.ServerVariables("LOGON_USER"). If a user is not a domain user, the website will direct him/her to a login.aspx instead of having the Windows authenication prompt, then set Session("user_name") = txtUserName.Text, and finally redirect to the website main page ?

C# - Getting Windows Username With JavaScript?

Jun 10, 2010

I have a site which is built in ASP.net and C#. Let's call it webapp. it uses a Form system to log on into it, and cannot be changed easliy.

I got a request to change the log in to some kind of windows authentication. I'll explain. Our windows login uses active directory for users to log into their windows account. their login name is sXXXXXXX. X are numbers. in my webapp, I want to take the users numbers from their active directory login, and check if those exist in the webapp database. if it exists, they will automatically log in. If it doesn't, they will be referred to the regular login page for the webapp system which is currently in use.

I tried changing my IIS to disable anonymous login and enabling windows authentication, therefore making the user browser to send it's current logged in user name to my webapp. I changed the web config as well from "Forms" to "Windows", which made my whole webapp obsolete as the whole forms system did not work.

My question is this - is there a different way for the browser only to send the username to my webapp? I thought maybe javascript, I just don't know how to implement that, if it's even possible. I know it's not very secure, but all this platform and system is built outside the internet, it's on a private network.

MVC :: ASP.NET Installers On Windows 7 As Domain User

Mar 12, 2010

A collegue of mine just spent 2 days trying to get ASP.NET MVC 1 installed on his computer. MVC 2 installed fine today, but 1 would still not comply. The issue was that he was running as a domain user (with both local admin privileges as well as Domain Admin privileges) but UAC was killing the installer because ASPNetMVC1.msi tries to run another MSI that silently fails if UAC is enabled. The fix was to disable UAC, reboot, and the install completed successfully and he was able to open MVC 1 projects again. I'm not sure if this is an MVC installer bug or a Windows 7 bug, but in either case a prompt should have been displayed informing the user of the error, or at the very least logging something to the log file (which we spent about an hour and a half analyzing for errors).
