Troubleshooting hybrid authentication issues
As we learned in Chapter 3, Securing a Hybrid Active Directory (AD) Infrastructure, there are four main AD DS integration points with Azure AD when using Azure AD Connect Sync to achieve cloud-scale identity and single control plane management. However, it’s not always as simple as installing an agent or application; you must ensure that the environment you are about to synchronize contains few errors and is well prepared and documented.
One of the tools provided by Microsoft to overcome some of the common issues to prepare your environment for synchronization is called the IdFix tool. The IdFix tool helps to identify duplicated and formatting issues within your on-premises directory, investigating AD objects and recommending remediation steps for identified anomalies prior to synchronization. Running the IdFix tool can be done directly from GitHub via this URL – https://raw.githubusercontent.com/Microsoft/idfix/master/publish...
