| 4489889 (OS Build 14393.2879) | Addresses an issue in Active Directory Federation Services (AD FS) that causes a duplicate relying party trust to appear in the AD FS management console. This occurs when you create or view relying party trusts using the AD FS management console. Addresses a high Active Directory Federation Services (AD FS) Web Application Proxy (WAP) latency issue (over 10,000ms) that occurs while Extranet Smart Lockout (ESL) is enabled on AD FS 2016. This security update addresses the vulnerability described in CVE-2018-16794. |
March 2019 |
| 4487006 (OS Build 14393.2828) | Addresses an issue that causes updates to a relying party trust to fail when using PowerShell or the Active Directory Federation Services (AD FS) management console. This issue occurs if you configure a relying party trust to use an online metadata URL that publishes more than one PassiveRequestorEndpoint. The error is, "MSIS7615: The trusted endpoints specified in a relying party trust must be unique for that relying party trust." Addresses an issue that displays a specific error message for external complexity password changes because of Azure Password Protection policies. |
February 2019 |
| 4462928 (OS Build 14393.2580) | Addresses interoperation issues between Active Directory Federation Services (AD FS) Extranet Smart Lockout (ESL) and Alternate Login ID. When Alternate Login ID is enabled, calls to AD FS PowerShell cmdlets, Get-AdfsAccountActivity and Reset-AdfsAccountLockout, return "Account not found" errors. When Set-AdfsAccountActivity is called, a new entry is added instead of editing an existing one. | October 2018 |
| 4343884 (OS Build 14393.2457) | Addresses an Active Directory Federation Services (AD FS) issue where Multi-Factor Authentication doesn't work correctly with mobile devices that use custom culture definitions. Addresses an issue in Windows Hello for Business that causes a significant delay (15 seconds) in new user enrollment. This issue occurs when a hardware security module is used to store an AD FS Registration Authority (RA) certificate. |
August 2018 |
| 4338822 (OS Build 14393.2395) | Addresses an issue in AD FS that shows a duplicate Relying Party trust in the AD FS management console when creating or viewing Relying Party Trusts from the console. Addresses an issue in AD FS that causes Windows Hello for Business to fail. The issue occurs when there are two claim providers. PIN registration will fail with, "400 Internal Server Error: Unable to obtain device identifier." Addresses a WAP issue related to inactive connections that never end. This leads to system resource leaks (e.g., a memory leak) and to a WAP service that is no longer responsive. Addresses an AD FS issue that prevents users from selecting a different login option. This occurs when users choose to log in using Certificate Based Authentication, but it hasn't been configured. This also occurs if users select Certificate Based Authentication and then try to select another login option. If this happens, users will be redirected to the Certificate Based Authentication page until they close the browser. |
July 2018 |
| 4103720 (OS Build 14393.2273) | Addresses an issue with AD FS that causes an IdP-initiated login to a SAML relying party to fail when PreventTokenReplays is enabled. Addresses an AD FS issue that occurs when OAUTH authenticates from a device or browser application. A user password change generates a failure and requires the user to exit the app or browser to log in. Addresses an issue where enabling Extranet Smart Lockout in UTC +1 and higher (Europe and Asia) didn't work. Additionally, it causes normal Extranet Lockout to fail with the following error: Get-AdfsAccountActivity: DateTime values that are greater than DateTime.MaxValue or smaller than DateTime.MinValue when converted to UTC can't be serialized to JSON. Addresses an AD FS Windows Hello for business issue in which new users aren't able to provision their PIN. This occurs when no MFA provider is configured. |
May 2018 |
| 4093120 (OS Build 14393.2214) | Addresses an unhandled refresh token validation issue. It generates the following error: "Microsoft.IdentityServer.Web.Protocols.OAuth.Exceptions.OAuthInvalidRefreshTokenException: MSIS9312: Received invalid OAuth refresh token. The refresh token was received earlier than the permitted time in the token." | April 2018 |
| 4077525 (OS Build 14393.2097) | Addresses issue where an HTTP 500 error occurs when an AD FS farm has at least two servers using Windows Internal Database (WID). In this scenario, HTTP basic pre-authentication on the Web Application Proxy (WAP) server fails to authenticate some users. When the error occurs, you might also see the Microsoft Windows Web Application Proxy warning Event ID 13039 in the WAP event log. The description reads, "Web Application Proxy failed to authenticate the user. Pre-authentication is 'AD FS For Rich Clients'. The given user isn't authorized to access the given relying party. The authorization rules of either the target relying party or the WAP relying party are needed to be modified." Addresses issue in which AD FS can no longer ignore prompt=login during authentication. A Disabled option was added to support scenarios in which password authentication isn't used. For more information, see AD FS ignores the "prompt=login" parameter during an authentication in Windows Server 2016 RTM. Addresses issue in AD FS where Authorized Customers (and relying parties) who select Certificate as an authentication option will fail to connect. The failure occurs when using prompt=login if Windows Integrated Authentication (WIA) is enabled and the request can do WIA. Addresses issue where AD FS incorrectly displays the Home Realm Discovery (HRD) page when an identity provider (IDP) is associated with a relying party (RP) in an OAuth Group. Unless multiple IDPs are associated with the RP in the OAuth Group, the user won't be shown the HRD page. Instead, the user will go directly to the associated IDP for authentication. |
February 2018 |
| 4041688 (OS Build 14393.1794) | This fix addresses an issue that intermittently misdirects AD Authority requests to the wrong Identity Provider because of incorrect caching behavior. This can effect authentication features like Multi Factor Authentication. Added the ability for Microsoft Entra Connect Health to report AD FS server health with correct fidelity (using verbose auditing) on mixed WS2012R2 and WS2016 AD FS farms. Fixed a problem where during upgrade of 2012 R2 AD FS farm to AD FS 2016, the powershell cmdlet to raise the farm behavior level fails with a timeout when there are many relying party trusts. Addressed an issue where AD FS causes authentication failures by modifying the wct parameter value while federating the requests to other Security Token Server (STS). |
October 2017 |
| 4038801 (OS Build 14393.1737) | Support added for OIDC logout using federated LDPs. This will allow "Kiosk Scenarios" where multiple users might be serially logged into a single device where there's federation with an LDP. Fixed a WinHello issue where CEP/CES based certificates don't work with gMSA accounts. Fixes a problem where the Windows Internal Database (WID) on Windows Server 2016 AD FS servers fails to sync some settings, such as the ApplicationGroupId columns from IdentityServerPolicy.Scopes and IdentityServerPolicy.Clients tables) due to a foreign key constraint. Such sync failures can cause different claim, claim provider and application experiences between primary to secondary AD FS servers. Also, if the WID primary role is moved to a secondary node, application groups will no longer be manageable in the AD FS management UX. This update fixes an issues where Multi Factor Authentication doesn't work correctly with Mobile devices that use custom culture definitions |
September 2017 |
| 4034661 (OS Build 14393.1613) | Fixes a problem where the caller IP address is nog logged by 411 events in the Security Event log of AD FS 4.0 \ Windows Server 2016 RS1 AD FS servers even after enabling "success audits" and "failure audits". This fix addresses an issue with Azure Multi Factor Authentication (MFA) when an ADFX server is configured to use an HTTP Proxy. "Addressed an issue where presenting an expired or revoked certificate to the AD FS Proxy server doesn't return an error to the user." |
August 2017 |
| 4034658 (OS Build 14393.1593) | Fix for 2016 AD FS server in order to support MFA certificate enrollment for Windows Hello For Business for on-premises deployments | August 2017 |
| 4025334 (OS Build 14393.1532) | Addressed an issue where the PkeyAuth token handler could fail an authentication if the pkeyauth request contains incorrect data. The authentication should still continue without performing device authentication | July 2017 |
| 4022723 (OS Build 14393.1378) | [Web Application Proxy] Value of DisableHttpOnlyCookieProtection configuration property isn't picked up by WAP 2016 in 2012R2/2016 mixed deployment [Web Application Proxy] Unable to obtain user access token from AD FS in EAS Pre-auth scenarios. AD FS 2016 : WSFED sign-out leads to an exception |
