Reads the submitted data from the password assistance form.

The following form fields are read as HTTP POST parameters: key username password1 password2 The key is used to retrieve the password assistance session. If the key is missing, or if the password assistance session has expired, the password assistance form will be shown instead of this form. If the password assistance session is valid, and if the username matches the username, for which the password assistance has been requested, and if the new password is valid, ILIAS assigns the password to the user. Note: To prevent replay attacks, the session is deleted when the password has been assigned successfully.
