Domino 8 webmail authenticatin

We are using Domino 8.0.1 on a Windows 2003 server. We have implemented webmail and it works great except for the authentication process.

Domino asks the webmail user to authenticate twice, once against /mail and once again /inotes.

How can I configure Domino so that webmail users only need to authenticate once?
