Finally, I found the problem.
I tried to set ACL in a host belongs to a cluster. But I didn't enabled ACL in the main cluster member (the CFS server - cluster file system-). 
With ACL enabled in this member is everything OK :)
Thanks to Spider Boardman, Anne Majeske and Joe Senuils because their help
--Original Message:
When I set ACLs on a file with the command:
   % setacl -d -u user::rw-,group::r--,other::r--,user:jdoe:rw- foo
I have this answer:
   %setacl: Warning: ACL processing is disabled for file: acl
I think ASL is enabled, because if I type
   %sysconfig -q sec
the answer is 
   sec:
   acl_mode = enable
Where is the problem?
