A really interesting guide is ready to download from Microsoft: Building Security and Directory Solutions for UNIX Using the Windows Server 2003 Active Directory Kerberos and LDAP Services.
This guide provides prescriptive guidance to enable Microsoft® Windows Server™ 2003 to be used for authentication and as an identity and authorization data store within heterogeneous Microsoft Windows® and UNIX environments. The guidance covers evaluating, planning, building, and deploying a security and directory infrastructure based on Windows Server 2003.
Really interesting, expecially because there are not too much guides about Windows interoperability with other OS that comes directly from Microsoft... check it!
