This is a follow-up to my own post about users not being able to change
their passwords. Somehow (perhaps with an update to BIND ?) the permissions
on /etc had changed so that /etc belonged to group bin and had rwxr_xr_x
I changed it to belong to group "auth", like the etc directory under /opt/K
and make permissions rwxrwxr_x
Seems to have worked. I'll probably never know how it got messed up.
