Ok - sorry that my question said 0775 and I knew that if I chmod 777
whatever that would make it _rwxrwxrwx but - and perhaps my problem is
really samba - I have the shares marked distinctly with force create
mode 0777 and the damn files & folders are created with _rwxr_xr_x (what
would appear to be 0755). Thus, it would seem that the permissions are
given to each user from their profile - which really isn't a profile
since they are all /bin/false for a shell (perhaps that is my problem).

This is very frustrating...

I think that I finally now understand umask - it is subtractive and not
additive - that my be my problem after all. I'll have to check it out
tomorrow.

Thanks,

Craig
