How can i filter the query with Drupal user id ?

Hi,

I have Drupal 6.x ad Alfresco 3.3 Community. Users have same login & password in Drupal and Alfresco.

With Drupal CMIS API module, connexion is ok and i can see all the containers : spaces and files.
But, this connexion use the default user (in the CMIS connexion string).

Can i "filter" results by the user id (or an Organics Groups id) ?

Thanks for answers.
