I would like to happen is then an new user on the master db i created that the username and password is also added to the slave db.

Answer 1

You can do this with either a TRIGGER or STORED PROCEDURE.

In your case i guess you could use something like this (not tested):

CREATE TRIGGER `user_update` AFTER INSERT ON `User` 
FOR EACH ROW 
BEGIN
    INSERT INTO `mydb`.`UserLogin` (`id`, `UserName`, `Pass`) 
    VALUES (new.UserId, new.UserName, new.Password);
END$$
