Hello,
 I want to create a folder like Share - Main folder and user 1, user 2 and
user3
 subfolders. I want give full permission in the Main folders for all users in
the
 group and user1 have write permission in user1 subfolder but user2 have read
 permission in user1 subfolder and vice versa. I have given chmod -R 755
 permission to the Main folder. User1 and User2 are part of group1.  But once I
 login to the Main folder, I get access to all the subfolders ie user1 can
enter
 user2 subfolders. Is there a way out?
