Your enterprise environment is presently using Active Directory Domain Services (AD DS).
You have been tasked with configuring directory synchronization with your Office 365 E5 subscription.
You need to set up support for Single Sign-on (SSO) and you want to confirm that all of the domain user names in use meet the formatting standard and will not cause any issues with the synchronization.
What should you do? (Choose the best option)
A) Make changes to the default configuration of Azure Active Directory (Azure AD) Connect sync
B) Confirm the synchronization settings in the Synchronization Rules Editor
C) Run Azure AD Connect sync with the defaults
D) Run the IdFix tool
E) Run the Synchronization Rules Editor and create a custom rule
Correct answer: D
The correct answer is (D) Run the Office 365 IdFix tool – the tool is used to search for problems in your directory and then fix the errors in the GUI.
Common errors detected by IdFix include illegal characters, duplicate entries / values, format violations, length limitations, to name a few.
While you can make changes to the default configuration in Azure Active Directory (Azure AD) Connect sync and / or run Azure Active Directory (Azure AD) Connect sync with the default settings, neither of these options would address any potential issues that might be found where there are the formatting exceptions and where these may cause issues with the synchronization.
The Synchronization Rules Editor is used to see and change the default configuration. It is configured with the default rules and you can add custom changes to the rules, such as flow, precedence, scoping, and so on, but this will not address the issue with any potential issues that might be found where there are the formatting exceptions and where these may cause issues with the synchronization.
