automatic user creation

Hello,

I want to have in a Drupal 7 installation a new user account automatically created each time a new node of a certain content type gets created.

This content type contais an email field from where I will take the account email information. For the username, I just tried to create a combination of first and last name fields also available in the same content type.

I used Rules framework with the following configuration.

Event : After saving new content

Condition : Content is of type (and I choose my content type described above)

Action : Create a new entity
