Hello Developers, as we are going to use the nopCommerce Platform as an internal eshop, we are requesting a posibility/solution for the following: 1. User authenticates via outlook web app (OWA) 2. User clicks the link for nopCommerce in the left navigation. (we have already implemented a link in the left navigation pane for the usage of nopCommerce.) 3. User doesn't need to authenticate again for the usage of nopCommerce. Authentication: OWA -> nopCommerce. Our Exchange Server 2010 is on Windows 2008 (x64) Platform. Is it possible for you implementing in nopCommerce to use the credentials entered before in OWA. Single-Sign-On would be really essential for us. Thank you all. Cheers.
