Integrating AD into Linux/Unix environment

[Laurie Zimmerman]

Hi,
 
I have been assigned with the task of introducing Active Directory 2003 to
an established Linux/Unix environment.  Currently file and print services
are provided by Samba 3.0 on Linux and clients (Windows/CentOS) are
authenticating to OpenLdap.  Documentation is plentiful for migrating from
Windows to Unix or integrating Linux into Windows AD environment but not the
other way around.  AD is being implemented because executives want Exchange
Server.  I know Kerberos 5 should be involved in this implementation, are
there any good white papers out there for this scenario?
 
Any help much appreciated!
