I've got everything and up and running, better than expected tbh.
The only thing I still need to find a solution for is being able to submit or reset the password when creating / editing a new user.
Any ideas?
have a look into the request, which is done on user-update at the normal user-update-form
there are fields for:
newpassword: true
passwordgenmethod: spec or g
passwordnotifymethod: s or e
specifiedpassword:
confirmpassword:
