Single Sign-On to Microsoft Exchange 2007 in a Clustered Environment
Users of the SAP NetWeaver Portal can take advantage of Single Sign-On to Web based Microsoft backend systems such as Outlook Web Access using SAP's SSO22KerbMap Module. In Exchange 2007, Client Access servers support Integrated Windows Authentication for Exchange 2007 virtual directories. As a result the SSO22KerbMap Module can now be installed on a Client Access server rather than on a backend server as with Exchange 2003 environment. Exchange 2007 now also offers the possibility to cluster mailboxes, a feature that will likely find a large adoption. We thus investigated a setup that consists out of a Client Access Server and CCR cluster (Cluster Continuous Replication).
