New user/Group always has OpenXChange Account by default

When i am creating a new user or group and not choosing any template, the attribute
isOxUser is set to OK

In this example you can see that even a group is using this via default


Is there a way to disable this default? So that it is set to "isOxUser=Not?

We have created some templates where that setting is set to “not” but when not choosing a templae an OX Account will be created.

maybe it is because of a user template?

maybe there is a default one? when creating a group or a user and selecting “none” as template, even then its an OX account, so seems like there is something in a plain user profil which is creating an ox account but i dont know where to change that (if possible)
