Howto setup of a directory server

[Arun Shrimali]

Dear All,  I am planning to setup a server with following features :

1. Authenticate  Unix and Windows users from an LDAP server (Fedora
Directory Server)
2. Map dedicated network drive for all the users under their username
using SAMBA.
3. Enable roaming profile
4. Control hardware of client m/cs
5. Authenticate LDAP for Squid proxy server also.
6. Local mail server which fetch mails from main server (external) for
defined users and make available on LAN.

Can anybody suggest me which combination packages is best for the
required setup and the best howto to setup the same.
