I believe ZFS uses "NFSv4" Acl's while Ext3 (or UFS) uses Posix. Supposedly the NFSv4 ACL's are closer to Windows. My experience was that ZFS gave more headaches than UFS in conjunction with Samba- with ZFS a perm such as "660" (i.e. user and group can read and write, but not rights to anyone ELSE) sometimes got interpreted by Samba as "everyone is denied" which trumped the user and group "allow" ACE's.

What does getfacl show on the file?

What do you see for the permissions and effective permissions under Windows? Are there "Deny" ACE's? Does windows complain about permissions being ordered incorrectly?

I believe that Centos 5.x/RHEL5.x DOES enabled ACL's on Ext3 file systems by default.

They have different ACL models. We'd need to see level 10 logs
containing these errors to be able to tell what is going on.
