/*
* Function: AFPUser_set_random_password
* Purpose:
* Set a random password for the user and returns it in passwd.
* Do not change the password again until AFPUSER_PASSWORD_CHANGE_INTERVAL
* has elapsed. This overcomes the problem where every client
* request packet is duplicated. In that case, the client tries to use
* a password that subsequently gets changed when the duplicate arrives.
