USER RELATED CONFIG SETTINGS
There different settings related to users:
user.model = Kwf_User_Model
Change this setting to use a custom user model. Your own user model has at least to extend
user.form.self = Kwf_User_Form user.form.grid = Kwf_User_Form
With these settings you can change the form used when editing users. Using that you can add new fields to a user.
selfis used when the user edits himself (link in the top right)
gridis used in the user management grid, use a different form if the user should not be able to change settings himself
user.passwordValidator = Kwf_Validate_Password3of4
Using that setting you can change the validator used on passwords. Set to false to have no validator at all.
The default is fairly strict (and relatively secure)
