I would like to catch the raw plaintext password if a user created or change his password. First i tried to handle this with signals.post_save at the User class, like this:

dispatcher.connect(update, signal=signals.post_save, sender=User)

The problem is, in the User model exists e.g. 'last_login'. So the save method called every time, the user logged in :( And with post_save i get only the hashed password and not the plaintext source password.

I found a simple way to trigger a user password change. I hacked directly into the django.contrib.auth.models.User.set_password() method. See the sourcecode.

There exists a discussion in the django-users thread about this.

from django.contrib.auth.models import User

# Save the original method
old_set_password = User.set_password

def set_password(user, raw_password):
    if user.id == None:
        # It's a new user. We must save the django user account first.
        user.save()

    #
    # Do something with the user obejct and the given raw_password ;)
    #

    # Use the original method to set the django User password:
    old_set_password(user, raw_password)

# Replace the method
User.set_password = set_password

Its not clear how to make use of this snippet? What is required in order to integrate into Django (and the Admin site)?
