[Samba] winbind and authentication with local accounts

[Philipp Braband]

Hi Rob,

thank you for your answer. 

>Depends on where you're talking about your users authenticating
My users should authenticate when they try to access a samba share. I don’t want to reconfigure every mapped samba share on the clients, because of this I want to use the "old" local accounts (like "peter", not "SAMBASERVER\peter").

I already tried "winbind use default domain = yes" and after winbind restart authentication failed for every user. I think the problem is that the users in the Active Directory have the same names (and UIDs) as the local users (because they are mapped with "idmap backend = ad").

Cheers,
Philipp

Now, after switching, they are forced to use SAMBASERVERNAME\peter. If they use only “peter” winbind tries to authenticate them against the AD which fails. Is there a way to “teach” winbind to try to authenticate every user locally if they dont use DOMAIN\peter ?
