Hi,
Access control lists are used to grant or deny permissions to users or groups in addition to those specified with traditional UNIX file access permissions.

control list (ACL) that applies to the file system; no assignment
means no authentication is used.
getacl - list access control lists (ACLs) for files (JFS File Systems only)
setacl - modify access control lists (ACLs) for files (JFS File Systems only)

You can search in forums OR www.hp.com OR google to find more..

ACL ... Access controll list.
This is used to set access to a file for a perticular user.
For example,
#ll myfile
-rw-r---- 1 root mygroup 11 Oct 10 10:12 myfile

Here the file permission is,
For root..... rw
for group(mygroup)... r
Now if there is a user (user1) who is NOT a member of mygroup need read permission for this file.
We can use the command to set acl.

#setacl -m u:user1:r-- myfile

To list the acl for this file ,

#getacl myfile

For more details,
#man setacl
