i want to be able to assign the group "readers" read access to guests/c1 but it says access denied. but it shows r-x acsess. can anybody help. i want to be able to control who has read access and not just give it to everybody.

What user are you when trying to give this level of access? If you are root, you can do:

chown root:readers /guests/c1
chmod 770 /guests/c1

don't want to change the default group. i already have r-x access, but i get access denied. don't understand why.
