Meteor.loginWithPassword returns Error: Incorrect password [403] - authentication

Question

I would like to add programmatically few users and login with one of them in my meteor app. I could not find any methods to add users at server side; so I added two buttons at client side to generate users and login with one of them. I can create users (I see them in mogodb) but I cannot login, getting Error: Incorrect password [403]. What I am missing?
This is client.js code
Template.hello.events({
'click #createUsers': function () {
console.log("Creating users...");
var users = [
{ email: "dgra#gmail.com", username: "gra", name: "gra", roles: ['admin'] }
];
_.each(users, function (user) {
Accounts.createUser({
email: user.email,
password: "admin",
profile: { username: user.username },
profile: { name: user.name },
roles: user.roles
});
});
},
'click #logIn': function () {
console.log("logIn gra...");
Meteor.loginWithPassword("dgra#gmail.com", "admin", function (err) {
if (err) {
console.log("loginError: " + err);
}
});
}
});

I could not find any methods to add users at server side
You can add users from the server. As the docs point out, Accounts.createUser runs anywhere. Here is a working example:
server/initialize.js
var insertUser = function() {
var user = {
email: 'dgra#gmail.com',
username: 'gra',
name: 'gra'
};
Accounts.createUser({
username: user.username,
email: user.email,
password: 'admin',
profile: {
name: user.name
}
});
};
Meteor.startup(function() {
if (Meteor.users.find().count() === 0) {
insertUser();
}
});
A few points:
You can add only one profile object.
Accounts.createUser only takes the arguments shown in the docs, so you can't add arbitrary objects.
If you are trying to use roles, the example there shows the roles being added after the account is created.
In the code above, I only add the user if there are no users in the database. This is convenient for testing since the user will automatically be inserted after a meteor reset (no button pushing requred).
