Ich kann keine neuen persönlichen Kennungen anlegen - Projekt "mit LMU-Kennungsimport"
In projects with the addition "with LMU account import", new personal accounts can no longer be created, but only existing LMU user IDs can be imported and equipped with additional permissions. As a master user, click on "Account | import" in the IDM portal menu to do this. See also How to give an LMU account further permissions for LRZ services?
If you are not offered an account for the new user to import when you click on "Account | import", then this user either does not yet have an account managed by the LMU or has an account in another department or faculty. In this case, you will have to set up an additional account (possibly a guest account) for him/her via your IT Operations Team at the LMU. See also Why can I no longer create personal acoounts?
