Probably not, acording to 
http://www.microsoft.com/PIRACY/samguide/tools/cal_guide/winnt.asp but 
IANAL and havn't read the full NT licence aggreement

*CALs are Required *
Windows NT 4.0 Server can be used for any of the following, in which 
CALs are required:
(*Note:* that some of these functions are "basic" and will be a common 
use of Windows NT Server, while others are more specialized and thus 
will be less common)

    * File Services--i.e. accessing or managing files on the network.
    * Printing Services--i.e. sharing and managing printers on the network.
    * Macintosh connectivity--file sharing and/or printing sharing.
    * Remote Access Services--i.e. accessing a server from a remote
      location through a communications link, including the use of
      Internet Connection Services.
    * Message Queue Server--i.e. sending or receiving messages from
      Message Queue Server.
    * Transaction Server--invoking component-based applications managed
      by Transaction Server.
    * Terminal Server Functionality--using Windows NT Server to display
      or use Windows-based or Windows NT-based applications on a device.

No mention of Authenticating users here... But you must not share any 
files from them.

Obviously, I will need licenses for each NT server, but if all I am doing with it is authenticating users, do I need a CAL for each user?  This is going to be a 2500 user installation, so it makes a big difference to the total cost.  If I do end up needing CALS, I will have to use some other authentication mechanism.  
>As I understand it, I can configure Samba to act as a PDC, but not as a BDC. Since this will be a mutli-site deployment, that won't work.  I guess that leaves me with NIS or LDAP.  Does  anyone have any reccomendations/suggestions/horror stories?

Technology is a word that describes something that doesn't work yet.
