Error when using LDAP Views within Rules
I solved the problem by another way : 

Within Rules :
First action : create a new entity (user) set the account name, set the account email with a fake value in the email.
Second action : unblock user (if blocked, the user account will not be synchronized from LDAP)

Then , when the account is created, the Drupal account is automatically synchronized from LDAP and get the good email.

(In LDAP configuration , be sure to configre LDAP User / BASIC PROVISIONING TO DRUPAL ACCOUNT SETTINGS/ Drupal Account Provisioning Events to  "Create or Synch to Drupal user anytime a Drupal user account is created or updated."
