The Official Samba 3 HOWTO and Reference Guide
http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/

Samba-3 by Example
http://www.samba.org/samba/docs/man/Samba-Guide/

Both contain very useful information about what you need. PDF versions 
are also available.
These books come with the Samba packages, too.

(One of the list members directed you to samba 4, but I don't think that 
the advice is appropriate. Please note that samba 4 is still in *alpha* 
stage.)
