NWA 7.3 : Looking for "security roles" (Policy Configuration) ...

Hi guys,

We deployed a simple application in our new SAP NW 7.3 JAVA instance; by calling the application, we receive "error 403 : Error: You are not authorized to view the requested resource."; this was fixed wihtin NW 7.x by adding a user/group within security roles of the selected component ( Visual Admin => Security Provider => Policy Configurations => select component and than security roles );

where to do this within NWA 7.3 ?

any ideas;

Thanks

Oliver
