Currently, when Just In Time Provisioning is leveraged, the only data that comes through is a first name, last name, and email address. When Entra AD is leveraged it is possible to bring additional attributes from Entra (i.e. Manager, Department, etc) which could be directly mapped to fields within BrightSpace.
We are currently developing an interface to facilitate these extra pieces of data (aside from doing bulk imports manually) but it would be really nice if this could just be fixed on your end.
