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
Processing section "[IsrAlgorithmData]"
Loaded services file OK.

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,
