[Samba] AD Integration drives me nuts

Wed May 5 12:38:55 MDT 2010

Hi

This has keeping me up for days now and I can't seem to find a solution
in the various wikis, howtos and whatsoevers, so here's the plot:

I have a W2K3 R2 x64 Domaincontroller (VM on vSphere4) and a CentOS 5.4
x64 fileserver (also a VM on vSphere4, same ESX-host), running Samba
3.0.33-3.15.el5_4.1 (rpm installation out of the box).

All I want to do is to have Samba authenticate against my DC. I've been
setting up Kerberos, Winbind and Samba according to the Wiki-Page
(http://wiki.samba.org/index.php/Samba_%26Active_Directory).

Authentication seems to work (i.e if I logon to the server via ssh using
the AD-Account, everything looks fine and even the created homedirs are
assigned to the group "domain users") however, If i try to map a windows
share from a laptop running XPpro, Samba won't accept the user neither
for the homedirs nor for the datashare.

So the big question is: where did I screw up and/or what did i forget?

This is what my smb.conf looks like at the the moment:

[global]
        workgroup = PROTEC
        realm = BSR.PROTEC-ENTERPRISES.COM
        password server = dc01-v.bsr.protec-enterprises.com
        preferred master = no
        server string = Samba FileServer Version %v
        netbios name = SAMBA-V

        # logs split per machine
        log file = /var/log/samba/%m.log
        # max 50KB per log file, then rotate
        max log size = 50
        log level = 3

        winbind separator = +
        winbind enum users = yes
        winbind enum groups = yes
        winbind use default domain = yes
;       winbind nested groups = yes
;       winbind nss info = rfc2307

        security = ADS
        encrypt passwords = yes

        idmap uid = 10000-20000
        idmap gid = 10000-20000

        username map = /etc/samba/smbusers 
	# just to map the root account to the AD-Administrator account
	# as well as the AD-Guest account to "nobody"

	template shell = /bin/bash
;       template primary group = "Domain Users"

[homes]
        comment = Home Directories
        valid users = $S
        readonly = no
        browseable = yes

[Data]
        comment = New K-Drive
        valid users = @PROTEC+domain users
        path = /mnt/sambashares/filestore
        writeable = yes
        browseable = yes

And here's what's in the workstation-log (not that i understand any of
it...):
