Hmm, what do you mean ? delete_s() and add_s() are not
functions that I made but the API for LDAP with Python
('s' for simple). I'm sure the rootdn and rootpw are correct,
because, as I wrote, nearly all of the calls are OK.

I'm calling the simple_bind_s() function at initialization.
Do I need to call it everytime I use a function ?
(just before add_s()  AND just before delete_s()) ?

Thanks,
Luc
