We have an enviroment with Windows 2003 Active Directory and Exchange 2003 Enterprise in a clustered setup. We have implemented RSA Secure ID for Windows to achieve 2 factor authentication. Most of our users use the full Microsoft Outlook 2003 client. Apparently RSA Secure ID for Windows is very problematic and we have many issues with it. The Exchange question is: Is there a way to authenticate to Exchange 2003 without using Active Directory Authentication? We are trying to find a two factor authentication method while bypassing Secure ID for Windows.
