Has anyone successfully configured the above to enable Single Sign-On? I would love to move away from Exchange but SSO is a corporate requirement.
I looked at this in some detail and concluded that the NTLM support on Outlook 2007 was only for encryption, it was not using SPA. I couldn't find a hidden registry setting or whatnot to switch it.
If you have a corporate support arrangement with MS, maybe ask them? Many people would love an answer. Even a trace of outlook using SPA with Exchange over IMAP would be interesting to see.
IMHO, clearly Dovecot is setup properly, Outlook Express works, Thunderbird w/ SPA works, etc. I believe MS has deliberately decided not to make SSO work in Outlook over IMAP specifically because that is a must have feature for enterprises, so it only works over MAPI and thus only with Exchange.
