O365-Connector: script o365_list_users fails

the script o365_list_users fails with the following message:
ValueError: No AD connection alias specified
The reason might be that the Univention Configuration Registry variable office365/adconnection/wizard is set to “defaultADconnection”.
This is correct, I can find this hint in the Description of the Variable.
The command manage_adconnections list the defaultADconnection as an alias correctly (status = initialized).
where can I define the connection as alias for the list_user script?
