Interesting timing - we just went live this past weekend and are currently working through an open ticket with IBM regarding user imports in MAS 9.1.
The process is significantly different (and more complex) compared to MAS 9.0. One critical point we discovered is that you must export the Full User details, not just the visible columns. Exporting only the visible columns, modifying fields like email or status, and then attempting to import can result in unintended consequences - in our case, it actually deleted the user. We have an active ticket open with IBM on this behavior.
When exporting the full user details, the system generates multiple rows per user (depending on group memberships and entitlements). This makes the import files much larger and requires breaking users into smaller batches to stay under the 500KB file size limit for import.
Additionally, password handling has changed. You can no longer directly update user passwords via import. For our ~400 users, we handled go-live by forcing password resets and email notifications using these three fields set to 1:
-
FORCEPASSWORDCHANGE
-
IDPAUTOPASSWORD
-
IDPEMAILPASSWORD
That approach worked, but it required careful batching due to the multi-row-per-user structure.
Overall, the process in 9.1 is considerably more cumbersome than it was in 9.0. We're working through it with IBM, but the user import/export workflow is definitely more complex than previous versions.

Hi guys,
First time posting in techxchange.
I found this thread, because we use the import user function as well, and are about to upgrade to 9.1.x.
When searching for information about this I found an article about the new template for importing users.
Maybe this can help you out, too?
