[Samba] Where is the default 'smb.conf' located?

[Joseph Phillips]

I compiled and installed the latest samba 3.0.0rc1.  I see that the binary
executable was placed in the default location of /usr/local/samba/sbin/smbd.

However, I cannot located the default smb.conf file.  I was expecting that
the 'make install' script would have copied this file somewhere onto my
system.

Where is the default 'smb.conf' file located?
