Mac OS X Homedirectories Mac (X/9) & XP H: Drive mapping

Hello, Could someone tell me how to configure Mac OS X 10.3.3 server to: 1) Allow single login for home directories from client to server 2) Map the H: Drive (home directory) on Microsoft PCs 3) Make the user profile store all data on the Server (Profile) Is there a step by step to setup an LDAP server? Complete setup line by line. Any one do this and get it working? Home directories is my focus! Thank you!
