Freshdesk azure integration problem

Hello,

We trying to make integration users from Azure( active directory) to freshdesk, and we trying to make automate user creation.  But when we done everythink, we get error “cannot be logged in as this user is not part of this organization”. We trying to find solution, but we dont have time, we want to start using grown plan and we have 370 users, and we dont want to create users with hand. 

Thanks i will wait for your respond.
