MapViewer integrated in Apex - Securing MapViewer Cookie Issue

Question

Hello,
I'm trying to secure my Mapviewer accesses. My MapViewer is contained in an apex page. As said in documentation (1.8.2) I have to used cookie to pass username(or what I want to authenticate the user) to the database. For doing this I have to put a package in my map schema and to configure datasource to use it.
Package code(nothing special) :
create or replace
PACKAGE BODY web_user_info AS
w_name VARCHAR2 (32767);
PROCEDURE set_user(p_name IN VARCHAR2)
AS
BEGIN
INSERT INTO TABLE1 VALUES('set machin');
COMMIT;
INSERT INTO TABLE1 VALUES('set_user:'||p_name);
COMMIT;
w_name := LOWER (p_name);
END;
PROCEDURE clear_user
AS
BEGIN
INSERT INTO TABLE1 VALUES('clear machin');
COMMIT;
INSERT INTO TABLE1 VALUES('clear_user:'||w_name);
COMMIT;
w_name := null;
END;
FUNCTION get_user RETURN VARCHAR2
AS
BEGIN
RETURN w_name;
END;
END web_user_info;
Datasource definition :
<map_data_source name="cuc"
jdbc_host="localhost"
jdbc_sid="xxxxx"
jdbc_port="1521"
jdbc_user="xxx"
jdbc_password="xxxxxxxxxxxxx"
jdbc_mode="thin"
number_of_mappers="3"
allow_jdbc_theme_based_foi="true"
plsql_package="web_user_info"
/>
It works like that except that it return J2EE authentication(oc4jadmin). set_user and clear_user are well executed.
Cookie Issue :
To make this work with cookie information I have to add a attribute to the datasource definition :
web_user_type="LOGIN_USERNAME_COOKIE"
This cookie is present in my apex page, details :
Name     LOGIN_USERNAME_COOKIE
Value     the_name
Domaine (host)     localhost
Chemin d'accès (path)     /apex/
Sécurisé     non
Expire le     À la fin de la session
It doesn't work with my cookie, the clear_user is well executed but set_user is no more executed.
Did someone already get through the cookie authentication feature ?
