Little documentation about ACL at  Solaris 10 :)
(-) The following example shows you how to substitute an ACL on the file named file1. The ACL permissions are configured as follows:
 
- The file owner has read, write, and execute permissions
 - The group has read and write permissions
 - The other users have read-only permissions
 - The user named user1 has read, write, and execute permissions on the file
 - The ACL mask has read and write permissions
 - The user named user1 has read, write, and execute permissions
 
# setfacl -s u::rwx,g::rw-,o:r--,m:rw-,u:user1:rwx file1Or using this command :
# setfacl -s u::7,g::6,o:4,m:6,u:user1:7 file1(-) Command copies the ACL entries from the file named file1 to the file named file2
# getfacl file1 | setfacl -f - file2
