Is it possible to auto login to IIS using an AD username and password when on the intranet (for example, someone has logged into the AD when logging on to their desktop) AND for them to access the same site when not on the intranet using a login page? Because IIS has to disable anonymous access in order for Windows authentication to work it is not possible to have a login page for users 'off site'?
If you are using Windows Authentication and you have anonymous access disabled as you say, then AD users should be able to access the site without being prompted to log in, and remote users who have not authenticated with AD will get a Windows dialog box that pops up in the browser and prompts the user to enter their AD credentials.

I'm looking for a way to auto-login a user that's logged in with an Azure AD user account into a web application.
What I've got so far: A web application that uses an Azure OAUTH workflow to login to the application. The user is forwarded to Azure's login page and after a successful login, he will be redirected to the web application with an oauth code that later used to get the user's identity.
Now I've got a new situation: Windows PC are part of a Azure Active Directory and the users all use AD users. Is it possible to use NTLM/Windows Integrated Authentication to auto-login when they open the page.
I looked for a way to enable NTLM/WIA for the OATUH flow to avoid that a user has to re-enter the credentials that he just used to unlock his pc.
Is there a way to do this?
In Internet Explorer, when I go to any site that is authenticated via Azure AD, the login page automatically chooses to log me in with my Windows Account. This functionality would typically be great, but I need to use different credentials (my clients).
How can tell IE to NOT automatically log me into Azure AD with my windows credentials?
When I use any different browser, the expected functionality exists and I am prompted to enter the login credentials I want. Also, the solution can not be "just use a different browser". Client uses IE for everything and won't allow users to install different browsers.
I am running Windows 10.
Thanks in advance
Opening IE InPrivate window should allow you to login with any user you need.
Use Ctrl+Shift+P or Settings Icon->Safety->InPrivate Browsing.
Is it possible to have automatic user authentication from Active Directory when open Internet Explorer without user enter username/password.
As right now. I have windows authentication, where users after open internet explorer, they have to enter he/she username and password from AD. So since the application has the same credential that the PC. I was wondering, how could i do so user don't have to log in when open internet explorer to use the web application.
I am thinking something like single sign on type of deal.
If your users already log in with their AD credentials your problem is almost resolved.
Your users have to add the site to the local intranet zone (so they aren't prompted for credentials) in their Interner Explorer Configuration. Also check in internet explorer security zone settigns that the following is enabled:
User Authentication -> Set Automating Logon Only In Intranet Zone
I am trying to understand concepts of windows authentication, forms authentication and their differences. I am confused. Can someone help me in clarifying this.
Thanks.
Windows Authentication provider is the default authentication provider for ASP.NET applications. When a user using this authentication logs in to an application, the credentials are matched with the Windows domain through IIS.
There are 4 types of Windows Authentication methods:
1) Anonymous Authentication - IIS allows any user
2) Basic Authentication - A windows username and password has to be sent across the network (in plain text format, hence not very secure).
3) Digest Authentication - Same as Basic Authentication, but the credentials are encrypted. Works only on IE 5 or above
4) Integrated Windows Authentication - Relies on Kerberos technology, with strong credential encryption
Forms Authentication - This authentication relies on code written by a developer, where credentials are matched against a database. Credentials are entered on web forms, and are matched with the database table that contains the user information.
Windows Authentication refers to authenticating against Windows user accounts on the box that the application is running on.
Forms authentication is a stand alone method of authenticating in .NET forms that you can hook up to some other system, such as a database.
It's pretty simple. Windows Authentication makes use of the Windows Login system.
http://en.wikipedia.org/wiki/Integrated_Windows_Authentication
And with Forms Authentication the user will need to provide a username and password manually.
http://www.asp.net/web-forms/tutorials/security/introduction/an-overview-of-forms-authentication-vb
The Forms Authentication also allows you to choose where you access the login data from. It could for example be stored in your own local database. While Windows Authentication is only going to use your Windows login data. This data usually comes from Active Directory, if your network is built using an enterprise/buisness/domain setup.

Windows Authentication-- The user will be authenticated on the IIS server against the credentials he provided when logging into his system. If the authentication fails then a pop up form will be displayed in the Internet Explorer asking for his credentials i.e. username and password.
Forms Authentication-- A default Login Page will be available like Facebook login, where user will be authenticated instead of automatically getting the credentials from the system credentials i.e. the current user of the Windows system. If the user requests a secure page and has not logged in, then ASP.NET redirects him/her to the login page. Once the user is authenticated, he/she will be allowed to access the requested page. Here IIS does not come into effect for authentication, it completely depends on the web application.
How do I change who is logged in (allow for another user to login) to an application that is using Windows Authentication without having the PC user log off?
You would be better served to use forms-based auth against AD with impersonation. Pass-through authentication is uneven and introduces a number of issues you don't even want to begin to deal with.
To clarify: Do you want to be logged in to Windows with one account and then be able to view a web site that uses Windows Authentication with a different user?
Maybe you can run the browser under a different account with runas.
Right-click on your browser icon, choose "Run as...", and provide the other user's credentials.
You could prevent IE (I assume) from automatically passing NTLM credentials. But then you'll get a login dialog.
You can change the "automatically login behavior" by doing the following in IE:
Tools -> Internet Options ->
Security tab -> Intranet zone (I
assume)
Then click "Custom level..." and
scroll to the bottom to User
Authentication -> Logon.
Select the "Prompt for user name and
password" option.
FF has similar options by going into "about:config" and change the "network.automatic-ntlm-auth.trusted-uris" setting.
