No profile information in account approval form

We have enable new account approval in Drupal. That is, a mail is sent to the site admin when a new user validates its email address. In that mail there is a URL (e.g http://mysite.com/admin/user/accounts/pending/create/) where I can see a form to accept or reject the new account. In that form, the profile fields for firstname and lastename are empty, even if the user fill them in the registration form.

I think the problem is in _ldapprov_profile(). The form is created by ldapprov_create() that take the account information from the db. The fistname and the lastname are stored in $data['first_name'] and $data['last_name']. _ldapprov_profile() invoke _ldapprov_register_form($data) that call _ldapprov_profile(), where the $edit argument of _ldapprov_profile() contains the $data array. The problem is that _ldapprov_profile access to $edit using the names of profile fields to retrieve the corresponding array values but, for example, the profile field for firstname is realname and not first_name meanwhile the profile field for lastname is surname and not last_name. _ldapprov_profile() is not using the good keys.
