Hello Norberto,
In your first example, I think the name of your apps in the apps.py config file
conflicts with the core Django auth module and it could explains the second
exception you get.
When you use a custom model in Django, the "migrate" command always create
additional table for group and user_permissions but they are never filled in
throught the admin site. According to me, Django creates these tables but they
are useless. Why ? I don't really know... Maybe it's depending on the table
creation process.
If you want to use group and permissions with your custom model, it will be
stored in auth_group, auth_group_permissions and auth_permissions tables.
Sorry, my answer doesn't really help you but that's is my understanding of
custom user model process at this time.
Sylvain.
