Overview

Build reliable Kerberos based single sign on for Active Directory without guesswork or fragile configurations. Kerberos runs behind every serious Active Directory deployment, yet many teams treat it as a black box until tickets fail, users lose access, or attackers abuse trusts and delegation. Troubleshooting in the middle of an outage is the worst way to learn how it really works. Kerberos Authentication for Active Directory: The Complete Guide gives architects, administrators, and security engineers a clear, practical path from protocol basics to full enterprise design. You get protocol level understanding that is always tied back to real Windows behavior, SPNs, delegation settings, browser SSO, hybrid access, and hardening. Understand Kerberos fundamentals in Active Directory, including the KDC role of domain controllers, ticket flows, PAC contents, and how group membership becomes access decisions. Design directory structures and trusts with Kerberos in mind, including multi forest and cross domain access patterns, selective authentication, and isolation strategies. Deploy and maintain service accounts, SPNs, managed service accounts, and keytabs for web front ends, databases, SMB file servers, and line of business applications. Use unconstrained, constrained, and resource based constrained delegation safely, including S4U2Self and S4U2Proxy behavior on Windows and how to avoid common abuse paths. Configure browser based SSO with SPNEGO and Integrated Windows Authentication, and diagnose token and header issues that break authentication for intranet applications. Integrate Kerberos into hybrid and cloud connected environments, including directory synchronized identities, cloud backed proxies performing constrained delegation, and identity based access to cloud file services. Work with encryption types, armoring with FAST, and claims and compound authentication, so that security policies, cipher choices, and ticket lifetimes match your risk and compatibility needs. Implement certificate based Kerberos and smart card logon with PKINIT, including mapping certificates to accounts, hardening configuration, and handling break glass accounts safely. Defend against Kerberos focused attacks such as golden and silver tickets, Kerberoasting and AS REP roasting, delegation abuse, and ticket based lateral movement with concrete prevention and detection steps. Build effective monitoring by focusing on Kerberos relevant event IDs, SIEM queries, and detection patterns for suspicious ticket issuance, PAC anomalies, and dangerous delegation activity. Troubleshoot real incidents with a structured approach that uses command line tools, ticket cache inspection, and network traces to isolate SPN issues, clock skew, ticket size errors, and policy conflicts. Run Kerberos in production over time with routines for KRBTGT rotation, service account reviews, platform changes, and forest or domain controller recovery. This guide includes full design patterns, step by step SSO rollout plans, and verification checklists for new applications and services so you can standardize how Kerberos is deployed and validated across your environment. Throughout the book you will find working PowerShell, shell, and configuration snippets that map directly to real world tasks such as querying SPNs, tuning encryption types, inspecting tickets, configuring delegation, and validating smart card and hybrid scenarios.
