Question

I’m new to Drupal6 and spent long time searching how to implement the following feature without success: I use Drupal as front-end/doc board for a web-app. I want to mirror all user account creation, update and deletion on this web-app, i.e. send user name and password.

I started coding a little module implementing hook_user (http://api.drupal.org/api/function/hook_user/6), but I am still wondering on several question concerning this hook:

1) I can’t find a doc concerning the $account fields, and thus don’t know how to retrieve the user name and password.
2) The insert operation informs that “The user account is being added”. Is that triggered when the user query an account or when his/her pending account creation has been approved?
3) User management on the ‘slave’ webapp is done through a URL interface. I only know the header("Location: http://webapp/users/add?user=martin&pwd=bla") PHP primitive, but I fear this will make a redirection, instead of just hiting the target page and continue code flow. Any suggestion?

Maybe some of you already programmed such a module, or would have links for more documentation?
Thanks in advance,
Martin

Here is the final piece of code that works. Note that the password is retrieved md5ified, so the slave webapp must be able to do so as well:

function mirror_registration_user($op, &$edit, &$account, $category = NULL) {
 $cmd = 'http://www.example.com/register?name='.$account->name.'&pass='.$account->pass;

 if($op == 'insert'){
$cmd .= '&op=insert';
drupal_http_request( $cmd );
 }
 else if($op == 'delete'){
$cmd .= '&op=delete';
drupal_http_request( $cmd );
 }
 else if($op == 'after_update'){ // 'update' is a "before update event"
$cmd .= '&op=update';
drupal_http_request( $cmd );
 }
}

Remark: in our case, registration requires admin approval. In this case, there’s an ‘update’ event. The ‘insert’ event is triggered as soon as the user queries an account.
