Hi

I have updated a samba AD memeber server to 3.0.23b in an environment, where
all Usernames are available in the AD and in NIS.

With 3.0.21b if I create a file with windows on a samba share
and open the security dialog, samba shows the DOM\USERNAME
string as owner of the file.
With 3.0.23b only the SID+RID of the user is shown.
The SID is the SID of the Samba-server.
If I add the domain-user USERNAME2 with the security dialog, this user
ist shown as
DOM\USERNAME2 until I reopen the security dialog.
Then I see alos the SID-RID
If I stop winbind and do the same procedure I get
Unix User/USERNAME1 for the owner of the file in the dialog
If I give another user USERNAME2 access to this file
and reopen the security dialog, the entry is not shown.

To make it work with samba-3.0.21b
we had this setting in smb.conf (winbindd running)

With this settings in the Windows file-dialog all
users appear DOM\USERNAME
and in Unix teh ACL's show the correct NIS Unix Users

    idmap uid = 10000-10000
    idmap gid = 10000-10000
    winbind use default domain = Yes
    winbind trusted domains only = Yes

Is it possible to make this work again with 3.0.23b?
(I know that the zero uid and gid range might be brain damaged,
but with this settings it works fine on both sides)

Greetings


Hansjörg
