We use that with another server for quite a while by now.
I usually does a great job but in rare cases, reason unknown,
either the module or the OS are messing up ACLs. I have to
confess this is one of the real old Sun Samba (3.0.3?) versions
and I haven't tried the latest.
The only hint I got that the problem occurs mostly with
moving folders or accesses by Microsoft Office tools

acl_xattr: ignore system acls = yes

I added

	acl_xattr: ignore system acls = yes

but it makes things worse as I cannot even grant myself (the authenticated
user) full access anymore even though I already have the full rights inherited

Is there any additional data I can provide?
