    Testing Entra ID Claims and Single Sign-On Enterprise Apps

    There is a class of Enterprise App in Entra ID (previously known as Azure Active Directory) that provides SSO (Single Sign-On) for apps outside of Microsoft 365 provided by other vendors.

  • Decommission ADFS When Moving To Azure AD Based Authentication

    I am doing a number of ADFS to Azure AD based authentication projects, where authentication is moved to Password Hash Sync + SSO or Pass Through Auth + SSO. Once that part of the project is complete it is time to decommission the ADFS and WAP servers. This guide is for Windows 2012 R2 installations…

  • RC4 Kerberos and AD FS Issues

    It has become common place to consider the position of the RC4 cipher in TLS connections, but this is not something that you can take from a TLS connection (HTTPS) and assume the same for Kerberos connections. If you do disable RC4 for Kerberos then there are some things to consider, especially is you have…

  • ADFS Adapter Issues With Upgrading MFA 6.3.1 to Version 7

    Upgrading the ADFS Adapter is not straight forward, though the readme notes for the upgrade make no mention of issues! To upgrade MFA Server 6.3.1 to 7 (so you can remove .NET 2 as a requirement, as that goes out of support soon) then you need to download the MFA installer to each MFA server…

  • How To Change Your Office 365 App Password

    If you are enabled for Multi-Factor Authentication (MFA) in Office 365 then you will need an App Password for some applications that do not support MFA. The user interface for creating a new App Password is well hidden in Office 365 (its not on the Password page for example). Post updated in 2016 to take…

  • Continuing Adventures in AD FS Claims Rules

    Updated 20th April 2017 There is an excellent article at http://blogs.technet.com/b/askds/archive/2012/06/26/an-adfs-claims-rules-adventure.aspx which discusses the use of Claims Rules in AD FS to limit some of the functionality of Office 365 to specific network locations, such as being only allowed to use Outlook when on the company LAN or VPN or to selected groups of users.…

  • Intermittent Error 8004789A with AD FS and WAP 3.0 (Windows Server 2012 R2)

    This error appears when you attempt to authenticate with Office 365 using AD FS 3.0 – but only sometimes, and often it was working fine and then it starts! I’ve found this error is due to two things, though there are other reasons. The full list of issues is at http://blogs.technet.com/b/applicationproxyblog/archive/2014/05/28/understanding-and-fixing-proxy-trust-ctl-issues-with-ad-fs-2012-r2-and-web-application-proxy.aspx. I found that this…

  • Changing AD FS 3.0 Certificates

    I am quite adept at configuring certificates and changing them around, but this one took me completely by surprise as it has a bunch of oddities to consider.

  • OWA and Moving Mailboxes to Office 365

    Lets imagine a scenario where you are using an on-premises Exchange Server and users’ use Outlook Web App, and then you move some mailboxes to the Office 365 cloud with Hybrid Coexistence enabled. The user might not know their mailbox has been moved and so yesterday they went to https://mail.company.com/owa, but today they need to visit…

  • Publishing ADFS Through ISA or TMG Server

    To enable single sign-on in Office 365 and a variety of other applications you need to provide a federated authentication system. Microsoft’s free server software for this is currently Active Directory Federation Server 2.0 (ADFS), which is downloaded from Microsoft’s website. ADFS is installed on a server within your organisation, and a trust (utilising trusted…

  • Changing ADFS 2.0 Endpoint URL for Office 365

    If you are configuring single sign-on for Office 365 then you will need a server running Active Directory Federation Services 2.0 (ADFS 2.0). When you install this you are asked for a URL that acts as an endpoint for the ADFS service, which if you are publishing that endpoint through a firewall such as TMG…
