ADFS Username Behavior

Problem

ADFS 4.0 on Windows Server 2016 tells users to log in with their full email address “someone@example.com.”  This generates many support requests, and complaints about too much typing.

Additionally, some extranet users may have email addresses not on the domain, and it’s unclear which email address they should supply.

This affects both the ADFS log in page, and the ADFS password change page.

Solution Methodology

ADFS Server 4.0 has PowerShell cmdlets to manage the content delivered to users during authentication requests: https://technet.microsoft.com/windows-server-docs/identity/ad-fs/operations/ad-fs-user-sign-in-customization

We’ll focus on the following

Get-AdfsWebTheme

and

Set-AdfsWebTheme

Of particular interest here is that we’re able to modify the JavaScript that runs on these pages.

Steps

Use PowerShell to manage custom ADFS Themes

  1. Export the Default ADFS Theme using this snippet:
     Export-ADFSWebTheme -Name "Default" -DirectoryPath c:\test
  2. Use your  favorite editor to open c:\test\script\onload.js
  3. Add the snippets from below (as desired) into onload.js
  4. Create a New ADFS Theme
     New-AdfsWebTheme -Name BetterDefault -SourceName c:\test 
    1. Set your new theme as the default (best for testing)
       Set-ADFSWebConfig -ActiveThemeName BetterDefault 
  5. Alternatively, you may update an existing theme with your code changes
    Set-AdfsWebTheme -TargetName "Default" -AdditionalFileResource @{Uri=“/adfs/portal/script/onload.js”;Path=“C:\theme\script\onload.js"}

Placeholder Text Solution

To update the “someone@example.com” placeholder on both the login and the password change ADFS pages, paste this code into your onload.js, and update your ADFS theme.

function UpdatePlaceholders() {
    var userName;
    if (typeof Login != 'undefined'){
        userName = document.getElementById(Login.userNameInput) 
    }
    if (typeof UpdatePassword != 'undefined'){
        userName = document.getElementById(UpdatePassword.userNameInput);
    }
    if (typeof userName != 'undefined'){
        userName.setAttribute("placeholder","Username");
    }
}

document.addEventListener("DOMContentLoaded", function(){
  // Handler when the DOM is fully loaded
  UpdatePlaceholders()
});

 

Formatting of the Username field

For single-domain organizations, it may be less than desirable to force users to enter the domain name as part of their username. To “fix” this requirement of entering usernames in a format of “domain\username” or “username@domain.com”, paste the following code into your onload.js.  Make sure to update your domain where appropriate.

Logon Username Format Solution

 


if (typeof Login != 'undefined'){
    Login.submitLoginRequest = function () { 
    var u = new InputUtil();
    var e = new LoginErrors();
    var userName = document.getElementById(Login.userNameInput);
    var password = document.getElementById(Login.passwordInput);

    if (userName.value && !userName.value.match('[@\\\\]')) 
    {
        var userNameValue = 'example.org\\' + userName.value;
        document.forms['loginForm'].UserName.value = userNameValue;
    }

    if (!userName.value) {
       u.setError(userName, e.userNameFormatError);
       return false;
    }


    if (!password.value) 
    {
        u.setError(password, e.passwordEmpty);
        return false;
    }
    document.forms['loginForm'].submit();
    return false;
};
}

Password Change Username Formatting Solution


if (typeof UpdatePassword != 'undefined'){
    UpdatePassword.submitPasswordChange = function () { 
    var u = new InputUtil();
    var e = new UpdErrors();

    var userName = document.getElementById(UpdatePassword.userNameInput);
    var oldPassword = document.getElementById(UpdatePassword.oldPasswordInput);
    var newPassword = document.getElementById(UpdatePassword.newPasswordInput);
    var confirmNewPassword = document.getElementById(UpdatePassword.confirmNewPasswordInput);

    if (userName.value && !userName.value.match('[@\\\\]')) 
    {
        var userNameValue = 'example.org\\' + userName.value;
        document.forms['updatePasswordForm'].UserName.value = userNameValue;
    }

    if (!userName.value) {
       u.setError(userName, e.userNameFormatError);
       return false;
    }

    if (!oldPassword.value) {
        u.setError(oldPassword, e.oldPasswordEmpty);
        return false;
    }

    if (oldPassword.value.length > maxPasswordLength) {
        u.setError(oldPassword, e.oldPasswordTooLong);
        return false;
    }

    if (!newPassword.value) {
        u.setError(newPassword, e.newPasswordEmpty);
        return false;
    }

    if (!confirmNewPassword.value) {
        u.setError(confirmNewPassword, e.confirmNewPasswordEmpty);
        return false;
    }

    if (newPassword.value.length > maxPasswordLength) {
        u.setError(newPassword, e.newPasswordTooLong);
        return false;
    }

    if (newPassword.value !== confirmNewPassword.value) {
        u.setError(confirmNewPassword, e.mismatchError);
        return false;
    }

    return true;
};
}

Forgot SharePoint Farm User Account Password

I had recently patched an inherited SharePoint 2010 Farm up to the December 2014 CU.  I’m currently prepping to migrate the farm to SharePoint 2013, but I needed to get it patched in the interim.

I successfully applied SP2, and the the December 2014 CU (14.0.7140.5000 – Much thanks to Todd Klindt’s SharePoint Admin Blog for the easy build number lookup), and all seemed well.

That is, until I had to change an extranet user’s email address.  These users don’t have mail accounts in our Exchange environment, but we do populate the mail attribute in AD with their corporate email address.  I made the change to the attribute in AD, and attempted to run the User Profile Synchronization (Central Administration | Manage Service Applications | User Profile Service Application | Start Profile Synchronization).

This action failed because the User Profile Synchronization Service was not running on the server! (Central Administration | Manage Services on Server).

I attempted to start the service but was prompted for the DOMAIN\SPFarm account! I searched all archives and documents, but found no reference to this password!  UH OH!!!!!

I finally found this post: http://joelblogs.co.uk/2012/09/22/recovering-passwords-for-sharepoint-2010-farm-web-application-and-service-application-accounts/

I had full administrative access to the server on which Central Administration was installed, so all I had to do was run a “one liner” in PowerShell.  Could it really be that easy?!

Here’s how easy it is:

&$env:windir\\system32\\inetsrv\\appcmd.exe list apppool 
 "SharePoint Central Administration v4" /text:ProcessModel.Password

I ran the command in my dev environment first (we always test foreign code outside of production, right?), and got this!

No Way.  That’s my Farm account password….in PLAIN TEXT! WHOA SCARY!

So, If you ever find yourself forgetting any of your IIS Application Pool Account Passwords, you now have the tool to recover it!

HOO-RAH!
