Good question @cdenesha. Apple School Manager and the Roster API only returns the person's Full Name, Managed Apple ID and optionally grade level in addition to some system identifiers. We do not receive any username fields nor do we receive any actual email addresses (might be a good feature request for Apple if this could be helpful information for your deployment).

Because of the nature of the dataset from the Roster API, we have been iterating workflows based upon the very critical Managed Apple ID.

As previously stated, JSS 9.93 will peel of the @school.edu for creating usernames and it will insert the Managed Apple ID as the email address verbatim when creating a new user (since email address is a required field for new users). As a part of our next release, we will extend the import logic as it relates to Managed Apple IDs and Email addresses.

In 9.96, a new user will still truncate the username (same as 9.93). Additionally, the Managed Apple ID will be inserted into the email field. The difference is that if there is an "appleid" subdomain, that will be automatically removed when populating the email field.

Example:
Johnny Appleseed has a Managed Apple ID of jappleseed@appleid.school.edu. Upon importing, no matching user is found. The new user for Johnny Appleseed would have a username of "jappleseed" and an email address of "jappleseed@school.edu".

In this example, you could see how a school might create Managed Apple IDs based upon user email addresses and then always insert the "appleid" subdomain. Upon importing into the JSS, the user might match (based upon available criteria) and append to an existing user. Alternatively, a new user would be created and the JSS would essentially revert to the proper email address by removing the "appleid" subdomain from the Managed Apple ID. Of course, this assumes that your email address username and your directory service username match.

Note: In the long term, Student ID numbers or Global Unique ID numbers (from SIS) will likely be the best matching solution. Until now, there haven't been many compelling reasons to append this extra detail to users throughout all of the various systems at play. Once those ID numbers actually propagate from SIS to directories and into the JSS, they will offer a much more accurate matching solution for Apple School Manager.

I'm having major issues with the different ID'S and matching them up in Powerschool. Has anyone got ASM import working yet?

We haven't, and we're finding that PowerSchool has assigned the same ID (which would end up being the "person_id") to some teachers and students. Has anyone else seen this?

I haven't, and have decided not to until it all works properly. Please see this comment for my primary concern.

How can we change Apple Classsroom so it displays student name instead of their email address.

Edit: Seems like it is displaying student names and the teacher was reporting something different.
