[Samba] Issues with FLOCK on NFS Share

[Georg.Biberger at partner.bmw.de]

Hello,

When I run "cat /etc/passwd | grep 'qqeda11'", on my linux box, I get:
qqeda11:x:79846:65600:Project Account for EDA:/home/qqeda11:/bin/bash

When I run "wmic useraccount where (name='qqeda11' and domain='MUC') get name, sid" on my windows box, I get:
Name     SID
qqeda11  S-1-5-21-43206524-2104247658-1151357142-1581344

so the user is an AD user, but also an unix user. I think this is a legal construct.
Is there another way to tell samba to use the correct mapping? What about modifying winbindd_idmap.tdb manually?

Georg
