I've run mkpasswd but the real question I believe is what domain should 
I run mkpasswd for? As I stated above I have run it for the Windows 
domain that I log into. However, again, my home directory is served by a 
Linux box using Samba but that link box does not participate in the 
Windows domain that I log into rather it just runs in it's own workgroup.

I know about SMBNTSEC. I have SMBNTSEC set on.

I will have to try those getfacl's when I get to work later. I will post 
them. However, which directories should I do this for? I mean my home 
directory's share point is \\<server>\<share>. I map this to my H drive 
then I mount H: /home/defaria.

Thanks for acknowledging my post...

Just a little note here but a proper signature delimiter is two dashes 
followed by a space. You lack a space.
