Group Based Directory Access

[Christian Kleinfeld]

Can anyone complain me if it's possible to use a Groupbased
Access to Sub-Directorys ?

At the moment we are using the following Directory Structure
wit .htaccess but thats a problem because some Groups can see
more then allowed.

Example says more then one thousend words.

/ # Serverroot
/public
/internal
/internal/prod_desc1
/internal/prod_desc1/tech
/internal/prod_desc1/plan
/internal/prod_desc2
/internal/prod_desc2/tech
/internal/prod_desc2/plan

So we want that Group Customer_prd1 cann see /internal/prod_desc1/tech
but not the main directory >/internal/prod_desc1/<.

And now we want the following Authorzition shema..

+-----------+---------+---------+---------+---------+
+ + Group 1 + Group 2 + Group 3 + Group 4 +
+-----------+---------+----------+--------+---------+
+ Section 1 + X + X + + X +
+-----------+---------+----------+--------+---------+
+ Section 2 + + X + X + X +
+-----------+---------+----------+--------+---------+
+ Section 3 + X + X + X + X +
+-----------+---------+----------+--------+---------+
+ Section 4 + X + X + X + X +
+-----------+---------+----------+--------+---------+

does anyone know a Apache Module or seperate Product which cann
fullfill our Requirements ?
