Net 1.1/2.0 and authentication against oracle

[Fabrice]

Hello,

I'm using two .net applications one in "1.1" et the second in "2.0".
VB.net is the used language

We have an oracle database with accounts and password.
I use the Microsoft provider.

I would like to activate authentication form against Oracle. Not to create a
new table with my users but check directly in oracle for users.

Do someone know how to do it or an Howto ?

thanks a lot
