Licenses for the MS365 connector can be assigned by group membership. The group needs an assigned udm office365/profile object. If the office365/profile refers to a license name that is not available in azure, no license is assigned and a traceback appears in the listener.log: The traceback is from the MS365 connector version 4.7 on UCS 4.4, but the code is also present in UCS 5. Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/univention/listener/api_adapter.py", line 166, in _handler self._module_handler.create(dn, new) File "/usr/lib/univention-directory-listener/system/office365-user.py", line 75, in create self.connector.create(udm_object=udm_user) File "/usr/lib/python2.7/dist-packages/univention/office365/connector/connector.py", line 519, in create self.new_or_reactivate_user(udm_object) File "/usr/lib/python2.7/dist-packages/univention/office365/connector/connector.py", line 479, in new_or_reactivate_user self._assign_subscription(udm_user=udm_object, azure_user=user_azure) File "/usr/lib/python2.7/dist-packages/univention/office365/connector/connector.py", line 456, in _assign_subscription deactivate_plan_ids = selected_subs_sku.get_plans_id_from_names(deactivate_plans) AttributeError: 'NoneType' object has no attribute 'get_plans_id_from_names' Updating the office365/profile objects to only contain valid licenses fixes the issue. https://help.univention.com/t/22699 We should catch the error and log a helpful message for the administrator.
