EntLib - Security -> Specify connectstring per role?

Hi group,

Im using:
Visual Studio 2003
ASP.Net 1.1
Enterprise Library (june 2005)

I've implemented security as described in Enterprise Library (EntLib) and I'm running into a problem

Example:
Roles:
- Operator
- Guest

Users:
- PersonA
- PersonB

Tasks
- Add record
- View record

Task Based authorization
- Role: Operator is allowed to execute Task: Add record
- Role: Guest is allowed to execute Task: View record

PersonA is member of Operator
PersonB is memebr of Guest

It all works great :)
HOWEVER BOTH USERS USE THE SAME CONNECTIONSTRING!?!?!?! :eek: :eek: :eek:
Is it possible to specify a connectstring to a role????

TIA
