Onderwerp: [Samba] WinbinD no longer available in Samba 4.7.6


Using Samba 4.7.6 (from standard repository) on Ubuntu 18.04.

After recent update, winbind failed to update, until I
disabled it (it
didn't start anyway). When run as

# winbindd -d 9 -i

it prints in the end:

server role = 'active directory domain controller' not
compatible with
running the winbindd binary.
You should start 'samba' instead, and it will control starting the
internal AD DC winbindd implementation, which is not the same as this

smbd currently is listening on 139 and 445 ports - thus, I assume, it
serves winbind itself. However, it isn't available any more
for PAM. How
shall I use Samba internal winbind implementation? When I initially
installed and set up ADs, wbinfo worked fine. Currently, it says:

# wbinfo -P
could not obtain winbind interface details:
could not obtain winbind domain name!
checking the NETLOGON for domain[] dc connection to "" failed
failed to call wbcPingDc: WBC_ERR_WINBIND_NOT_AVAILABLE

How do I make winbind available (that means available for
PAM,a s well)?
I suggest reading :
Short version: samba-ad-dc is starting winbind, so dont start it manualy.
For pam support install : libnss-winbind libpam-winbind
Configure nss_switch.conf and run pam-auth-update

And set these to to no, when your done testing.
         winbind enum users = yes
         winbind enum groups = yes
See your users: id username or getent passwd username.

None are returned, with 'yes' or 'no' settings. And

As far as I see, the recommendations from the above document are met.

But winbindd refuses to start (I cited its message), and no other 'winbind' process is running, either.

How do I make samba 4.7-provided winbind run?

Are there possibly missing some winbind settings (the smb.conf has been generated by domain upgrade process).
