I have this ldap scheme.

dc=company, dc=com
    - ou=users
        - uid=aaaa  
            - ou=car 
                - brand=audi  
                - brand=chevrolet  
        - uid=bbbb  
            - ou=car
                - brand=ford  
                - brand=audi  
                - brand=chevrolet 
        - uid=cccc  
            - ou=car
                - brand=ford   
                - brand=chevrolet 
        - uid=dddd  
            - ou=car
                - brand=ford  
                - brand=audi  

I need to get only users who don’t have ford car. It is possible to do it in one request ?

Thank you
