That is correct.

I'm not sure what this means.  Sorry for my ignorance.

Even if I have a configuration problem, I shouldn't expect the core dump 
should I?

Here's the result of 'testparm -s'...

Load smb config files from /etc/samba/smb.conf

Am I "missing an idmap configuration option that maps the other windows 
domain controller that is providing the account information (login 
name/password) to a local 'home' directory."

Thanks for the help Craig,
