I'm writing a module in drupal to support remote authentication. Basically, our drupal site will have its login/logout controlled by a parent site for the company.
This is working for new users. ie: users of the main site who have not yet been to the drupal site. Their user account is automatically created with data retrieved from the main site.
However, when the user logs in again (second time - so they now have a "uid" in the "users" table) when they come back from the remote login page, the user hook is called with op = "load" , uid = 0, and the account is set up for an anonymous user. This I don't understand.
The code goes basically like this:
--
if ( ! mymodule_user_exists( $username ) ) {
user_external_login_register( $username, "mymodulename" )
}
$account = user_external_load( $username );

Any hints appreciated. -Matt
