!!How to use this stuff
Right! Onto the juicy stuff. First off, you need to make sure your ext2/3 partitions are mounted with the `acl' option. If they aren't, you will get this:
+<verbatim>
cyan /# setfacl -m u:rgh:rwx tmp
setfacl: tmp: Operation not supported
+</verbatim>
-So, make sure (acl) is in the options list.
+So, make sure (acl) is in the options list in /etc/fstab for the patitions you want to use acls on
.
+EG:
+<verbatim>
+ /dev/sda7 /tmp ext3 defaults,acl 0 2
+</verbatim>
!!!ACL Basics
An ACL for use with the command line looks like [[gu]:<group|user>:perms.
So, to give group `techies' rwx access to /techie_folder, you would type:
+<verbatim>
setfacl -m g:techies:rwx /techie_folder
+</verbatim>
To see the results:
+<verbatim>
getfacl /techie_folder
+</verbatim>
You'll get something like this:
+
!# file: techie_folder%%%
!# owner: root%%%
!# group: staff%%%
user::rwx%%%

other::r-x%%%
The -m just means you are modifying the ACL directly from the command line, as opposed to from stdin later. man setfacl reveals all!

!!!ACL's with Samba
Samba 3 supports using libacl to support full ACL access to Samba shares. You need to ensure it's compiled into Samba (it probably is) and install libacl. Then it seems like you don't have to do anything more. See http://www.bluelightning.org/linux/samba_acl_howto/ for a small howto.
