Samba 2.0.7 PDC and MS-Exchange/SNA Server

[Fabricio Bianco Abreu]

Products belonging to Microsoft BackOffice family (e.g. MS Exchange Server,
MS SNA Server and MS SQL Server) may use WinNT domain controllers
information about users and domain groups to implement access methods for
their own services.

Given these cenarios:
- MS Exchange may assign mailboxes to a certain domain user; 
- MS SNA Server may assign rights to a certain domain group access a pool of
logical units.

I REALLY need to migrate a full MS Network to a linux/unix/samba
environment. Six NT machines are providing login, profiles, file, Exchange
and SNA services to about 400 Win95 workstations. 

Questions are: 
- Are these products able to use Samba 2.0.7 Domain Controller
functionalities concerning users and groups??
- Would MS Exchange Server perceive Samba 2.0.7 as a NT DC and perform
authentication to its mailboxes users?? As I see it, it resembles the login
process.
- Would Win95 workstations share files and printers on a user level base (in
opposition to share level sharing) having Samba 2.0.7 for domain controller
??

I am not interested on User Manager or Server Manager stuff. It is not an
issue if I have to use a Samba box to administer user information on such
domain.

Sorry for my lame English.
