kdewallet : how to add application into access control ?

[Bruno Costacurta <cob1@biz.tiscali.be>]

Hello,

I installed kdewallet but every time I started application using it (ie. 
kmail) I have to re-enter its password. 
How to add kmail into allowed access control to avoid this cumbersome 
procedure ? kdewallet manager propose an Access Control menu but it seems 
impossible to add an application.

Thanks.
Bye,
Bruno
