[Samba] ACL Question [Repost]

I experience similar symptoms with both 3.0.10-as-found-in-fedora-core-3
and samba-3.0.11. One difference is that I haven't been able to make
smbcacls get as far as denying permission. Shouldn't this command work?

smbcacls //localhost/research research1.txt -a ACL:AD\\MarketingGroup:ALLOWED/0/RWX -U AD\\administrator
Failed to parse ACL ACL:AD\MarketingGroup

Note that when I remove the -a to just list ACLs, it works fine, so a 
parsing error doesn't make much sense here:

[root at ADSambaFP1 ~]# smbcacls //localhost/research research1.txt ACL:AD\\MarketingGroup:ALLOWED/0/RWX -U AD\\administrator

Yes, I can use getfacl and setfacl successfully and yes, ACLs are enabled
in Samba and on the ext3 file system in question (POSIX ACLs).

Thanks for any information.
