star acl problem

Hello! Today I started to use star on SLES8. I wrote backup to tape with following command: /usr/bin/star c --file=/dev/st0 -acl -H=exustar ./ But when I try to restore sometimes star can restore acls: backup:/BACKUP/test # star -x -acl -H=exustar --file=/dev/st0 star: current './' newer. star: Invalid argument. Cannot set ACL 'user::rwx,group::rwx,group:belbank:rwx #effective,mask::r-x,other::---' for 'apps/belbank/BACKUP/client/'. star: Invalid argument. Cannot set ACL 'user::rwx,group::rwx,group:belbank:rwx #effective,mask::r-x,other::---' for 'apps/belbank/BACKUP/client/1/'. Any ideas?
