Simple authentication against a PDC

[Matthew Miller]

Hi,

This may not be the best forum for my question, but I'm at a loss for 
resources...

I'm working on an application that needs to authenticate users against a PDC 
in our domain. Basically, I just want a true/false value as to whether a 
username and password is valid or not.

I'm still waiting for my copy of ORA's Samba book to arrive and I'm 
wondering if I can get some pointers on how to accomplish this.

Thanks for any suggestions.

Matthew
