Automatically sync users from one Azure AD to Azure AD
Can we have an inbuilt Azure AD functionality to sync user from one or multiple azure ad to a central Azure AD (shared tenant) so that it removes the overhead burden of creating and deleting user in central Azure AD.
You already have the concept ready it's just you need to provide an in-house functionality. (https://docs.microsoft.com/en-us/azure/active-directory/app-provisioning/scim-graph-scenarios)
Also the available functionality like whitelisting the complete domain in B2b is not of great help because users leaves the home tenant and we don't have any sign of it also we need additional attribute like (Phone No. / Country / Designation) etc.
