[Samba] Samba 3.0.2 & Exchange 2003 / Active Directory?

[Book, Jesse]

	My dilemma is this.  My company is in the midst of doing some moves.  Our 
network will be merged with another section of the company.  They are 
completely MS servers, while all my servers are running linux / samba.  Our 
new CTO told me that the company IS moving to Exchange 2003 (in ~ 6 months), 
and said that he is open to use linux for authentication, file servers, print 
servers, etc IF I can point him to other companys who have this setup.  
	I am currently running samba 3.0.2 as a PDC authenticating a mix of win98, 
win2k, and XP clients (I've been told we're moving completely to XP for 
clients), but I have not dealt with any integration with Exchange.  The 
googling I've done so far hasn't turned anything I can give the CTO. 

*	I was wondering if anyone was using Samba 3 with Exchange 2003 using the 
Samba server to authenticate Exchange users?

*	If you have this kind of setup, what problems did you run into during 
setup/implementation.

*	If you know of anyone that has done this, and has written about it, please 
forward the article / URL to me.

Thanks for your time, Any information would be extremely helpful
