Migrating a Web Server to IIS 5.0

Integrating UNIX and Windows 2000 Server Security

Windows 2000 Server and UNIX handle their respective user accounts very differently, complicating security implementation in a mixed environment. If you plan a multistep approach to migrating from UNIX to the more secure Windows 2000 Server environment, you might find it necessary to use a mixed authentication scheme during the early stages.

Windows 2000 Server implements the Kerberos v5 authentication protocol, a mature Internet security standard, as the default protocol for network authentication. This provides a foundation for authentication interoperability with other platforms, such as UNIX. For more information about the Kerberos v5 protocol, see Security in this book.
