Identity and Access Control (Analysis Services - Multidimensional Data)
SQL Server Analysis Services requires all users to be authenticated by the Windows operating system. Because Analysis Services does not have a provision to generate and maintain user credentials, as SQL Server database engine has, Analysis Services might allow anonymous connections. However, this is an operating system distinction that maps multiple possible users into one user defined as anonymous. This page provides links to help you locate the information that you must have to work with specific security packages, anonymous connections, and the Kerberos protocol.
