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.
