I don't blame you. And I don't think you can use them on a machine 
that's a member of a domain, but I could be mistaken there. They're 
local accounts, but definitely with a twist. I was pleasantly surprised 
that ssh didn't choke on them, but I didn't really suspect it as a root 
cause for file permission issues, or I would have mentioned that in my 
very first message.

Bingo. I had just such an account already. It works as expected, i.e. 
correctly.

Could we "fix" it by allowing the user to set their default group? As I 
said in my original message, changing the group from None to Users in 
/etc/passwd solved my problems.

Of course, if we don't really understand these accounts, then we don't 
know why that solved my problem, or if the same thing would work for 
someone else. Hmmm. Never mind.

Attached. Your gut seems to be working today...
