[Samba] Samba 4 WBC_ERR_DOMAIN_NOT_FOUND

[steve]

Hi everyone

Ubuntu 11.10
Version 4.0.0alpha18-GIT-23a0343

Added a user called steve2. The first time I used winbind, no problems: 
wbinfo -i steve2 gave me the info I needed for user and group.

But now it doesn't work:
wbinfo -i steve2
failed to call wbcGetpwnam: WBC_ERR_DOMAIN_NOT_FOUND
Could not get info for user steve2

I can logon OK:
smbclient //localhost/home -Usteve2
Password for [SITE\steve2]:
smb: \>

Looking through the archives I found this:
Workaround:
1. Run sudo dpkg-reconfigure -plow libpam-runtime
2. Deselect "Winbind NT/Active Directory authentication"
3. Select OK

but I only have this:

PAM profiles to enable: │
│ │
│ [*] Unix authentication │
│ [*] Likewise Open │
│ [*] GNOME Keyring Daemon - Login keyring management │
│ [*] ConsoleKit Session Management │
│ [*] Inheritable Capabilities Management

IOW I can't do the workaround.

Any ideas anyone?
Thanks Steve.
