After looking through the code for building custom credential providers for Windows 7, I managed to get my own tile to show up on the logon screen, and can logon as the desired user. However, I am trying to implement a system where an event (a Bluetooth device in range) triggers a logon/unlock, without needing to click on the tile.
I can set it to fill in the password automatically (maybe I will implement pulling the password from the device), but either way, I must click the tile first. If it is locked, I need to click "Other Credentials" before that, too.
How would I go about implementing the logon credential provider without displaying a tile on the logon screen? It would be nice if I could keep the existing password option focused, and bypass it the moment the device comes in range.
EDIT: I made some progress, but I still think I need to do this without a tile. If I set the *pbAutoLogon parameter to true, and fill in the username and password before that, then the following behavior occurs:
If the default credential is selected (lock/unlock), then I need to click on "other credentials". If I log off, both credentials are displayed by default.
If both credentials are shown, and my provider is enabled after that, then the logon is automatic.
If my provider is enabled first, then "other credentials" is selected, I still need to click on my provider, after which logon is automatic
You need to change your credential settings to log in automatically and then your provider needs to tell LoginUI that the credentials have changed.
One of the sample credential providers supplied by microsoft works in this way.

We have a working a custom credential provider,
and a working way to change password when user is logged in.
We are trying to handle the use-case of changing password when the
password is known as expired.
We managed to get the status in ReportResult:
STATUS_PASSWORD_MUST_CHANGE we save that the password must change.
Windows display a message to say, the user need to change his password,
but when clicking on OK, it fallback to logon screen, not our CPUS_CHANGE_PASSWORD scenario.
We have tried to force this scenario when enumerating credentials, but still, the LOGON UI is still drawn instead of the CPUS_CHANGE_PASSWORD one.
How can we do to redraw the UI with the correct Scenario after clicking on OK?
Thanks
When I try to connect to Dynamics 365 CRM with the Plugin Registration Tool I get the following permission error:
"You don't have permission to access any of the organizations in the
Microsoft Common Data Service region that you specified. If you're not
sure which region your organization resides in, choose "Don't know"
for the CDS region and try again. Otherwise check with your CDS
administrator. Parameter name: EMEA"
I have the System Administrator role
I can sign-in to the web interface and work with no issues
I'm sure of our region, tried to login with and without it ("Don't know" option)
Also tried with an application password as our organization uses multi factor authentication
Using the latest version of the tool on Nuget (9.0.0.9506 in the about dialog)
I can connect to my trial server the same way
We had a user who was able to connect with the same user roles set
This seems machine and account independent. Other users including the organization creator are getting the same error
We are directly connected to the internet, no proxies
One solution I've read suggested cleaning the cache files which don't appear on my system. And we get the same error on clean installations.
Solved by leaving the "Show Advanced" checkbox unchecked and not entering User ID / Password. Then a second dialog opens for credentials and 2FA authentication which just works.
You don't need an application password, as you'll be asked for MFA in the next step.
I don't know how our old teammate was able to sign in with the "Show Advanced" option selected. He was getting the same dialog and continue.
I have a squid proxy server with basic SQL db authentication. When setting it on a client machine, the user is prompted with a dialog that asks for the username/password.
When they are entered and the save box is checked, the prompt no longer appears in IE but chrome asks every time it is started.
My question - is it possible to preconfigure the username/password in registry or somewhere else? I have tried the
http://username:password#server:port
and variations of it with no success. When that string is entered the browsers ignore it completely and proceed with no proxy.
I looked into setting up ntlm on squid but it seems that if the client is on a different domain the user will still be prompted.
You can choose the below steps to enforce IE using the same connection during the whole authentication procedure.
Click Start, click Run, type regedit, and then click OK.
Locate and then click either of the following keys in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings
On the Edit menu, point to New, and then click DWORD.
Type ReleaseSocketDuring401Auth, and then press ENTER.
On the Edit menu, click Modify.
Type 0, and then click OK.

I want to implement a self reset password functionality for Windows 7 users. When the Logon screen prompts the domain users should be presented with a forgot password button which will open the password reset wizard. So the problem is how to add a command button to the standard windows logon screen?
I know about GINA in Windows XP as mentioned here:
Adding command button to Windows Logon screen
But this topic is 3 years old, and with Vista / Windows 7 Microsoft came up with "Microsoft Windows Credential Provider".
Those button are called "Tiles", and they are implemented in a Credential Provider. Anything you read about a Gina will not work in Vista or later.
Those tiles a created by the LogonUI.exe process, itself launched by Winlogon.exe. LogonUI.exe runs with high priviledges. You don't want to run anything there. Besides, any wizard you run will run under the system account. Security issues aside, anything that resets the password of the current user will not work.
But let's assume that you have a solution that can reset a user's password. Like a web site (or a local application) that :
Ask for the user's name
Ask some security questions
Connects to Active Directory to reset the password
Then here is a way to implement the functionality.
Create a user, a domain user if possible. Give it a name and a password easy to remember, like "reset" and "reset". Make shure that everybody knows the password.
Change the shell of that user to Internet Explorer, that you would be running in kiosk mode, pointing to your web application.
Now when someone wants to reset their password, here is what they will do :
Use the standard Windows Credential Provider, like they do every day, but with the user "reset" and the password "reset".
Instead of the normal Windows shell, they will be presented with your password reset web application.
The user resets their password and they are instructed to log off using CTRLATLDEL
They can log in with their own username and brand new password.
This idea can be improved upon if you are ready to write some code:
Instead of Internet Explorer, write a simple web application that wraps the web browser control. if the application is closed, or any other funny business, logoff.
Hack one of the Credential Provider samples to supply the well know password reset username and password, making password reset merely a click away
Change that password reset credential provider's image to reflect the password reset functionnality.
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.
