When I create a new user, that new user automatically assigned to have admin right in purchase inventory module. 

I have other module that have 3 access right. Admin, Technical, and User. I want technical and user access right is read only towards product template regardless of any right from purchase inventory module

I already add below access right in the csv security

access_product_template_for_technique,model_product_template,model_product_template,my_module.group_parameter_technique,1,0,0,0
access_product_template_for_utilisateur,model_product_template,model_product_template,my_module.group_parameter_user,1,0,0,0
access_product_product_template_for_technique,model_product_template,product.model_product_template,my_module.group_parameter_technique,1,0,0,0
access_product_product_template_for_utilisateur,model_product_template,product.model_product_template,my_module.group_parameter_user,1,0,0,0
access_sale_product_template_for_technique,sale_model_product_template,sale.model_product_template,my_module.group_parameter_technique,1,0,0,0
access_sale_product_template_for_utilisateur,sale_model_product_template,sale.model_product_template,my_module.group_parameter_user,1,0,0,0

But technical and user still can create and edit product template

When I change purchase right from admin to user, that user is read only towards product template.

My goal is I want technical and user access right is read only towards product template regardless of any right from purchase inventory module
