Cross Tenant Synchronization Attributes Missing

Question

We have setup cross tenant sync to one of our subsidiaries, users are coming over as expected, but not some of the attributes we were expecting to see. We currently use onpremisessamaccountname in one of our applications claims, but that attribute is not available with the synced users. Does anyone know if it is possible to sync it or do we have to look at having multiple claims based on user/group?

Hi @Kyle Adamski

Thank you for reaching Microsoft Q&A.

I understand that you are trying to use the onPremisesSamAccountName but the attribute is not available with the synced users in the Cross Tenant Synchronization.

In general default Entra Connect Sync rules, the attribute "SamAccountName" gets synced to Entra ID as "onPremisesSamAccountName".

When using cross-tenant synchronization, some attributes may not be available for synchronization. The onPremisesSamAccountName attribute is one of the attributes that cannot be synchronized by cross-tenant synchronization.
To sync the onPremisesSamAccountName attribute in a cross-tenant synchronization setup, you need to ensure that the attribute is included in the synchronization schema.

You may need to extend the schema to include the onPremisesSamAccountName attribute if it’s not available by default.
