User Access Control

Hi,
Do we have any way to limit or Control the access of all ldap users through CDS to internet websites(porn,gambling,gaming etc…) and local CLD Applications like Konsole,Linguist,Games,Kuser,wicd and other systems level configurations and settings.In this case i want that CDS should be able to control all LDAP users(rather then going to each CLD to do settings ).Is this possible to impose restrictions on users instead os system ? .
Detailed and early reply will be much appreciated.

Thanks
Raj

At the moment it is possible to use a proxy service.
The proxy service does not support filtering by site name, can only blocking ports for the user.

In the future, will add additional capabilities, including filtering using LDAP.
