Windows Authentication C# MVC3 - asp.net-mvc-3

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

Azure Portal Login automatically uses Windows Account

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.

IIS 7.5 onwards - Windows login via a web page

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.

How to log off in the dynamic crm

I log in the dynamic CRM and I want to use a another account to log in again. How to log off the CRM system?? I have cleaned the cookies and it doesn't work.How to do it?
If you are using CRM Online, you can use the "Sign Out" link in upper right hand corner of the page.
If you are running On Premise you will have to take a few extra steps as CRM is looking for your Active Directory credentials. An easy way would be to change the security settings in Internet Explorer so that you are prompted to enter credentials.
Security Settings -> Local Intranet -> Custom Level - Uncheck Automatic login with current username and password

For those using Safari for OSX login to Dynamics CRM on Premise, if you didn't use Keychain to store password for this site, you will clear the connection when you turn off Safari.
But if you use Keychain to store, you need to use Keychain Access and manually remove password related to Dynamics CRM. Then turn off your browser. You authentication cookie will be killed. When you reopen Safari and browse Dynamics CRM, if will prompt and ask for password again.

ASP.NET change logged-in user using Windows Auth without logging off PC?

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.

How to change users in TortoiseSVN

I was setting up another user to use our SVN repository. He didn't have a username/password, so I logged in with my credentials. We now have a username/password for him.
How do I get TortoiseSVN to logout and forget the old password so I can enter the new username/password?
Open Windows Explorer.
Right-click anywhere in the window.
Click TortoiseSVN → Settings.
Click Saved Data.
Click Clear beside Authentication Data (see below).
Check the authentication items to clear.
Click OK.
All saved Authentication Data for all projects is deleted.
You will have to re-enter credentials to reconnect.
There are several ways to do it, through settings or by deleting the cache.
Deleting the cache is the most versatile method. First, locate it:
On XP, it was located here:
C:\Documents and Settings\%USER%\Application Data\Subversion\auth\svn.simple\
On Vista, it was located here:
C:\Users\%USER%\AppData\Roaming\Subversion\auth\svn.simple\
Then look in those files with Notepad, and delete the one with your credentials.
If you want to remove only one saved password, e.g. for "user1":
Go to the saved password directory (*c:\Users\USERNAME\AppData\Roaming\Subversion\auth\svn.simple\*)
You will find several files in this folder (named with hash value)
Find the file which contains the username "user1", which you want to change (open it with Notepad).
Remove the file.
Next time you will connect to your SVN server, Tortoise will prompt you for new username and password.
When you use Integrated Windows Authentication (i.e., Active Directory Single Sign-On), you authenticate to AD resources automatically with your AD credentials. You've are already signed in to AD and these credentials are reused automatically. Therefore if your server is IWA-enabled (e.g., VisualSVN Server), the server does not ask you to enter username and password, passing --username and --password does not work, and the SVN client does not cache your credentials on disk, too.
When you want to change the user account that's used to contact the server, you need use the Windows Credential Manager on client side. This is also helpful when your computer is not domain joined and you need to store your AD credentials to access your domain resources.
Follow these steps to save the user's domain credentials to Windows Credential Manager on the user's computer:
Start Control Panel | Credential Manager on the client computer.
Click Add a Windows Credential.
As Internet or network address enter the FQDN of the server machine (e.g., svn.example.com).
As Username enter your domain account's username in the DOMAIN\Username format.
Complete the password field and click OK.
Now when you will contact https://svn.example.com/svn/MyRepo or a similar URL, the client or web browser will use the credentials saved in the Credential Manager to authenticate to the server.
After struggling with this and trying all the answers on this page, I finally realized I had the incorrect credentials stored by windows for the server that hosts our subversion. I cleared this stored value from windows credentials and all is well.

Replace the line in htpasswd file:
Go to: http://www.htaccesstools.com/htpasswd-generator-windows/
(If the link is expired, search another generator from google.com.)
Enter your username and password. The site will generate an encrypted line. Copy that line and replace it with the previous line in the file "repo/htpasswd".
You might also need to Clear the 'Authentication data' from TortoiseSVN → Settings → Saved Data.
