Greeting Jeremy Allison,
I can't have better answer than for the creator of this feature. :-) I
must apologize, the result of the testparm don't give warning or error
(on Samba 3.0.20). My mistake was that the word 'owner' was not reconize
in smb.conf.
In conclusion this feature did not resolve my ACL(EA) entry problem with
Samba.
Robert
