Hi, There is a link for the Video to show how you can enable the Odoo Accounting feature for community versions. https://www.youtube.com/watch?v=Oj3XywS0bEk 

Hello,

If you want it by code,

Try this code in XML

-----------------------------------------

<record id="base.default_user" model="res.users">
    <field name="groups_id" eval="[(4,ref('group_account_manager'))]"/>
</record>

or

If you want to do it from Interface, 

Go to users, and there you can find an Inactive User "Default User Template"

add that user in the group you want. next time you creating user, the user will be taken the defaults settings from this template user.

Thanks & Regards
