Hi
Is it possible to add to Entra ID Connect to sync an attribute like employeeID that exists in both in prem AD and Entra ID without adding a custom extension attribute?
Thanks

2023-10-02T12:23:34.26+00:00 Thanks, but as employeeID is already an attribute on Entra ID the questions was if it is possible to sync without using extensions. Feels a bit stupid to create a custom umployeeID in Entra when there already is one existsing

Since employeeID attribute is not a default attribute in Entra and is stored in the additional properties, you wouldn't be able to map it directly otherwise.
