Here is what to do to undo acl's:

                setacl -d d:u::,d:g::,d:c:,d:o: dir_name

-----------------------------------
This command will find ACL files recursively
on your JFS file system.  The command is:

    find / -aclv "user:*:r??"

TEST that worked:
 root@server [/data/files/]

 >--> find . -aclv "user:*:r??" -exec cp -p {} /tmp/ACLtest \;

 -----------------------------------------------------
 >--> ll /tmp/ACLtest/
