Typically I just adjust who is a member of the group by editing the 
group using vi /etc/group, the Group has full rwx access to the share 
folder.  I don't see listings like your examples in /var/log/secure, but 
there are entries for ssh authentication, etc. Where do I look in the 
samba config file to find that listing?
