i've got vsftpd install on an ubuntu server 9.10

i can use chroot to restrict users to their own home directories but i also want to give them access to a group shared folder

for example, users foo1 and foo2 are local users in the group foos i want foo1 to have access to /home/foo1 and /svr/foos and foo2 to have access to /home/foo2 and /svr/foos

other notes: using pam and enforce local user ssl already tried mount --bind but it does weird permissions when you try to mount bind multiple users to the same
