I have implemented the NTLM in my Portal.
I have also implemented an iView which displays the Web Outlook's Calander.
The problem is that authentication is needed before seeing the calander. How can I implement SSO, so that the user won't have to type his UserName and Password. Note that the UserName and Passwod the portal receives at the NTLM stage are identical to those the user needs to
authenticate in front of the exchange. The problem is how to "tell" it to the exchange...
