Thanks.

The root of the issue is this automatically generated entry in your
idmap.ldb:

# record 12
dn: CN=S-1-5-32-544
cn: S-1-5-32-544
objectClass: sidMap
objectSid: S-1-5-32-544
type: ID_TYPE_GID
xidNumber: 10
distinguishedName: CN=S-1-5-32-544


What we need to do in your case is to remove that record, so it becomes
regenerated as an IDMAP_BOTH.  We also need to remove the generation of
that record from provision. 

The issue is that as a GID, you of course can't own a file.  The ntvfs
file server papered over this issue (didn't deal with file ownership at
a unix level), but the smbd file server needs to correctly set posix
permissions. 

I hope this clarifies things.  If you can please file a bug, I'll try
not to forget this.

Thanks,

Andrew Bartlett
