Why a small mistake in HR can have big consequences
You can build the finest automation, but if the department or start date is wrong, someone still ends up with the wrong access. That is why reliable user management starts with the data Entra ID bases its decisions on.
The user object in Microsoft Entra ID has dozens of properties, the Entra ID user attributes. Most of them are for the address book: phone number, street, postcode. A small group does more. Those fields are read by features that act on them: a dynamic group that adds someone, a licence that is assigned, a workflow that starts on a date, an approval that goes to the manager.
That makes them the input of your entire automation. A rule such as user.department -eq "Finance" is exactly as good as the department field. If it says "Financien", "Fin." or nothing at all, someone falls outside the group, without an error message. How to write such rules is covered in dynamic groups based on HR attributes. This article is about the fields themselves: which ones matter, where they come from and how to check that they are right.
We deliberately leave two fields aside here: the userPrincipalName and the email address. How to build those and what to do when someone changes their name is covered in account naming.
