Implementing and troubleshooting authentication and authorization protocols: a John Craddock Masterclass

Environments are no longer constrained by network boundaries, and we need to embrace disparate systems, and implement the appropriate authentication and authorization protocols to support our ecosystems. Only through a deep understanding of the protocols will you be able to validate and troubleshoot your systems.

International identity guru John Craddock’s new 5-day hands-on Troubleshooting Masterclass complements and follows on from his acclaimed Microsoft Identity Masterclass, and provides you with a thorough grounding in the different protocols, and shows you how to configure, test and troubleshoot.

All too often issues can take days to fix, whereas with the correct tools and techniques, they could have been resolved in minutes. After this class, you will be in an exemplary position to dramatically reduce resolution times.

About John Craddock’s Troubleshooting Masterclass

The primary identity provider is Azure AD but you will learn how to integrate your applications with other identity providers. You will work with a range of troubleshooting tools including Fiddler, Wireshark, Postman and browser development tools to hone your troubleshooting skills. You will learn how to work with and troubleshoot the following protocols:

  • WS-Federation
  • SAML-P
  • OpenID Connect
  • OAuth 2.0
  • REST API access
  • Windows Kerberos authentication and Kerberos Constrained Delegation

The course begins by introducing all concepts swiftly and factually before diving deep. For some, the intros will be a revision and consolidation exercise, for others, the intros may reveal new concepts. If you need more explanation about any of the topics while you’re on this Masterclass, your job is to ask – there is no such thing as a silly question! See the course outline for what you’ll learn, day by day.

Hands-on labs

This Masterclass includes more than 25 hands-on labs to strengthen and augment your learning. They will consolidate your knowledge and will enable you to discover a variety of troubleshooting tools and techniques. All the labs run in the cloud, and this hands-on environment (which you will also be able to access for two months from the start of the class) is perfect for troubleshooting.

Sharing and discussions

Your growing skills as a troubleshooting ninja will be greatly enhanced during class discussions. We discuss the practical tips and tricks that you already know, and those you have learned in class. Some of the more complex hands-on exercises you will do are augmented with a ‘tips and tricks pdf guide’, and also a quiz which becomes a discussion point for sharing experiences and expertise.


  • You will have access to the hands-on lab environment for two months from the start of the class.
  • We will give you a build document that shows how to build the labs in your own VM, and will supply you with all the Masterclass websites and scripts.
  • A comprehensive course manual is also provided – both a hard copy and a pdf – and it will be an invaluable ongoing reference source.

Who is the course for?

Specially developed to complement his Identity Masterclass, John’s new Troubleshooting Masterclass is for experienced administrators with hands-on system administrator’s skills who want to learn how to implement and test authentication and authorization protocols, and how to troubleshoot and resolve hard-to-fix situations.

If you haven’t already attended John’s Identity Masterclass, you should be familiar with Azure AD concepts and terminology, and know how to:

  • Create and manage users, groups, OUs and group policies in on-premises AD
  • Perform basic server/DC troubleshooting (for example check if a service is running, and
    restart it)
  • Add a DNS record
  • Add an URL to a browser’s Intranet zone
  • Create and manage users and groups in Azure AD
  • Register OpenID Connect and OAuth 2.0 applications in Azure AD
  • Run Azure AD PowerShell commands
  • Perform basic network and protocol tracing using Wireshark and Fiddler

Some of these skills may have been gained by attending the Identity Masterclass, but the expectation is that you have used these basic skills in a live production environment and now you want to delve deeper. If you have these pre-requisite skills, the Troubleshooting Masterclass can be done independently.

The Troubleshooting Masterclass is designed to complement John’s Microsoft Identity Masterclass, and there is very little overlap.

  • The Troubleshooting Masterclass focuses on configuring and troubleshooting authentication and authorization for resource access. John will explain the management aspects of Azure AD only briefly.
  • Some troubleshooting skills are covered in the Identity Masterclass,but this Troubleshooting Masterclass goes to a much deeper leveland covers more complicated scenarios.
  • The Troubleshooting Masterclass uses Azure AD and an on-premises AD as the primary sources of identity.  The only minor overlap with the Identity Masterclass hands-on is when we configure some aspects of Azure AD and Azure AD Connect.

John recommends that students do not to take the Identity Masterclass and the Troubleshooting Masterclass back to back. He says: “After taking the Identity Masterclass a student should go back to apply the techniques they have learned before returning to do the Troubleshooting Masterclass.”

If you want to resolve issues quickly, this Troubleshooting Masterclass is a must!
