Seems that since the admin account is created with the initial database setup it doesn't include the salt value. So when the config file gets changed to use store_salt=true it breaks the admin's ability to login. Seems like the best work-around if you want to use salts stored in the database is to leave that value as false initially, login as the admin, set the value to true, create a new user, then change that new user's group to the administrator group id and delete the original administrator. From then on, all new users will have salts in the database, and everyone will be able to login.
