Update Password Page

All the above commands will get applied to the sign-in page and update the password page by default. On top of that, the update password page has one additional cmdlet to modify the page description

Set-AdfsGlobalWebContent -UpdatePasswordPageDescriptionText "This is the Contoso Update Password page."

Advanced Customization

AD FS in Windows Server provides built-in support for customizing the sign-in experience. For a majority of these scenarios, the built-in Windows PowerShell cmdlets are all that is required. In some cases, AD FS administrators may want to provide additional sign-in experiences that are not possible through the existing PowerShell commands that ship in-box with AD FS. In certain instances, it is feasible for administrators to customize the sign-in experience further by adding additional logic to onload.js that is provided by AD FS and will be executed on all the AD FS pages.

Customizing the AD FS experience by using onload.js

The theme that is shipped out-of-the-box is called Default. Export the default theme. The following cmdlet creates a custom web theme, which duplicates the default web theme

New-AdfsWebTheme –Name custom –SourceName default

To export the theme, use the following cmdlet. Locate onload.js under the script folder in the directory that is specified in the export cmdlet and add the custom logic to the script.

Export-AdfsWebTheme –Name default –DirectoryPath c:\theme

Update the theme with the modified onload.js. Use the following cmdlet to apply the update onload.js to a custom web theme.

For AD FS on Windows Server 2012 R2:

Set-AdfsWebTheme -TargetName custom -AdditionalFileResource @{Uri='/adfs/portal/script/onload.js';path="c:\theme\script\onload.js"}

For AD FS on Windows Server 2016:

Set-AdfsWebTheme -TargetName custom -AdditionalFileResource @{Uri='/adfs/portal/script/onload.js';path="c:\theme\script\onload.js"}

Apply the custom web theme to AD FS using the following cmdlet.

Set-AdfsWebConfig -ActiveThemeName custom

Additional Customization samples

Consider the below code snippet to accept SAM-account name as a login format on an AD FS form for Sign in and Update password page, the complete code is attached within the article. The original onload.js, the one that comes with the default web theme will execute on all ADFS pages and hence always make sure that proper logic to distinguish the current page context is handled.

Sign in Page

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 = 'contoso.com\\' + userName.value; // replace contoso.com with custom ADFS Name
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;
};
}

Update Password

if (typeof UpdatePassword !== 'undefined') {
UpdatePassword.submitPasswordChange = function () {
var u = new InputUtil();
var e = new UpdErrors();
var userNameValue;
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('[@\\\\]')) {
userNameValue = 'Contoso.com\\'+userName.value; // replace contoso.com with custom ADFS Name
document.forms['updatePasswordForm'].UserName.value = userNameValue;
}
if (userName.value && userName.value.match('[@]')) {
var matchresult = userName.value.match('[@]');
var firstat = matchresult[0];
var splitresult = userName.value.split(firstat);
userNameValue = 'contoso.com\\' + splitresult[0];
document.forms['updatePasswordForm'].UserName.value = userNameValue;
}
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;
}
var error = document.getElementById('error');
error.innerHTML = '';
return true;
};
}

How do I install the Password Update code above - do I just place anywhere in the onload.js? Does it work with ADFS 2016? Thanks for providing!
