[Samba] Authentication incompatibility?

I've tried to build several different version of Samba and they all have 
the same problem as long as I use the client I build I can connect to 
the server I built. However the client I built can't connect to other 
Samba or windoze servers and other samba clients and windoze machines 
can't connect to the server I built. The error always points to the 
password being rejected.

I am compiling on an Athelon/64 that is running a 32 bit install of 
Linux. Is one of the "auto*" tools getting confused? Or is there 
something else someone knows about that might be causing the 
authentication process to be incompatible?
