group permissions based on folder perms

grcunningham · 05-26-2005, 09:06 PM

I'm using Samba on SuSe 9.3 as a PDC and for file sharing, works great. Here is my issue:
user jim: member of docs, finance, busmgmt
the rights for all files in these shares are 770, only the owner or those in that particular group should have access to those files
if jim creates a file in the docs share, I want the group set to docs
if jim creates a file in the finance share, I want the group set to finance
etc...
right now it sets the group to the particular users primary group, which is users...this gives everyone in the company access to all new files..real bad!
is there a way that I can have the group set for all new files to the group that owns the directory?
thanks, Gary

maybe you want to work with a SGID bit ? (set group id bit)

lhope this will help you:
