Okay, thank you, I think I finally get how this works:
When figuring out what groups jarboed is in, first /etc/groups gets hit 
for secondary groups.  *After that, winbind gets hit to see if jarboed 
is in any other groups.*  When "winbind use default domain = no" in 
smb.conf (the default) winbind doesn't bother checking because there is 
no domain associated with "jarboed", but when "winbind use default 
domain = yes" in smb.conf, winbind will hit the PDC to determine what 
groups MY_DOMAIN+jarboed is in and tack on the additional 
MY_DOMAIN+Domain Users, etc, groups to the list of secondary groups for 

And for system accounts that don't exist on the PDC (mostly all of 
them), winbindd_getgroups just spits up the error that there is no such 
domain user (like "root") to be in any groups?
