How to link the same user's accounts (same email) instead of duplicating it? about loopback-component-passport HOT 5 CLOSED

To achieve what you want you should look at overriding the profileToUser(provider, profile) function.

The default one does the following:

If you replace it with a function that looks like this:

function profileToUser(provider, profile, options) {
  return {
    firstName: profile.name.givenName,
    lastName: profile.name.familyName,
    email: profile.email,
  }
}

The passport component will properly match the player with its email and not duplicate the account.

var generatedEmail =
(profile.username || profile.id) +

var email = provider === 'ldap' ? profileEmail : generatedEmail;
var username = provider + '.' + (profile.username || profile.id);
password = utils.generateKey('password');
userObj = {
username: username,
password: password,
};
if (email) {
userObj.email = email;
}
return userObj;
} else {
password = utils.generateKey('password');
userObj = {
password: password,
};
// if profileMapping exists, map each provider field to the appropriate user field
options.profileMapping.forEach(function(field) {
userObj[field.userField] = stringToRef(profile, field.providerField);
});
}
return userObj;
}

this is not working fine, suggest something else to do this manually when new user registered.
