[Samba] ADS Kerberos Authentication without winbind problem

>> Further to this problem I have found it impossible to get any syntax to succesfully mount a Samba 3.0.2 share 
with Kerberos authentication using the BSD "mount_smbfs" (on Mac OS X), where this does work without problems 
when the local UNIX account is a Winbind account. Again I see the behaviour where a ticket is obtained by the 
client but somewhere this is not being associated with the local account on the Samba server.
So again I ask, does anyone know how to get the Samba server and client system to treat a Kerberos ticket
such as "user at TESTLAN.BBC.CO.UK" as being associated with local UNIX account "user"?
Is anyone else running Samba as a AD member server without winbind?

	thanks Andy.

Hello list,

Due to problems with winbind on Solaris I cannot use winbind. Instead I need to get Kerberos authentication from 
ADS working with a Samba member server with local UNIX user accounts.
So to briefly describe my configuration, I have an account in AD and a duplicate account locally on my Samba server 
which has been initialised with "smbpasswd -a user password". My Samba server has successfully joined my AD domain
and can successfully obtain Kerberos tickets.

This does work in principal but I have the following problem, in order to get Kerberos authentication I have to use 
syntax like this on the Windows client

net use \\bbcwwp-sun24\share /user:bbcwwp-sun24\user

This works perfectly, but because my AD domain is called TESTLAN if you try and access the samba share by either 
of the following methods:

from windows explorer directly accessing the URL "\\bbcwwp-sun24\share"

or from command line "net use \\bbcwwp-sun24\share"

They both fail, presumably because its assuming that the user account is "TESTLAN\user" which will not work 
(I tried this syntax manually and it didn't work). Although they fail I have verified that the client is still 
obtaining a ticket for the Samba server "HOST/bbcwwp-sun24".

Given that I don't expect my users to be using "net use" in order to access data on a Samba share I basically 
don't have a working solution at present. Is there anything I can tweak in the Samba config to get round this? 
Any help much appreciated,

	thanks in advance,  Andy.
