[Samba] Samba4.2rc4 with winbindd in config cannot start samba process

Hi all,

 

I have tried to migrate a domain from Samba3 to Samba4 Ad and now using
samba RC4. Referring to release note document, I should use winbindd instead
of winbind. However, I cannot start samba4 daemon when using winbindd
parameters, but can start using winbind parameters.

 

Would you please help. Thanks. Below is the current config file:

   # workgroup = NT-Domain-Name or Workgroup-Name

   workgroup = ICS

   realm = icshk.local

Never having migrated an S3 domain to an S4 AD domain, I am not sure 
that you get a new smb.conf created for you, but I would be very 
surprised if you don't.

Go back to the smb.conf that the upgrade provided, you do not need and 
shouldn't add about 90% of what you added, the major mistake you made 
was this: 'vfs objects = full_audit', YOU HAVE TURNED OFF THE
DEFAULTS!!!!

With Samba 4.2, if you want to use the winbind daemon instead of the

I use the following (on the DC, Bind9-Backend): 

   workgroup = SAMDOM
   realm = samdom.example.com
   netbios name = circe
   server role = active directory domain controller
   server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbindd,
ntp_signd, kcc, dnsupdate
   idmap_ldb:use rfc2307 = yes
   dbwrap_tdb_mutexes:* = yes
   domain master = no
   # added as per
https://wiki.samba.org/index.php/Authenticating_other_services_against_AD
   kerberos method = secrets and keytab

It might also be worthwhile to check both the compilation and the 
provisioning settings. 

./configure --prefix=/usr/local/samba \
            --with-piddir=/usr/local/samba/var/run \
            --with-syslog \
            --with-quotas \
            --with-acl-support \
            --enable-cups \
            --with-ads \
            --with-shared-modules=idmap_ad

where the last two lines are for a member server.
You might not need all the lines, but this might be a good start.
Provided You want to set up a new domain, do the provisioning

samba-tool domain provision --use-rfc2307 --interactive --use-xattrs=yes

Check also the DNS settings. The wiki evolved quite a bit over the 
last year - it is now very reliable. Be sure to carefully execute 
all the necessary steps and do all the proposed checks in between.

I use the following (on the DC, Bind9-Backend): 

   workgroup = SAMDOM
   realm = samdom.example.com
   netbios name = circe
   server role = active directory domain controller
   server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl,
winbindd, ntp_signd, kcc, dnsupdate
   idmap_ldb:use rfc2307 = yes
   dbwrap_tdb_mutexes:* = yes
   domain master = no
   # added as per
https://wiki.samba.org/index.php/Authenticating_other_services_against_AD
   kerberos method = secrets and keytab

It might also be worthwhile to check both the compilation and the
provisioning settings. 

./configure --prefix=/usr/local/samba \
            --with-piddir=/usr/local/samba/var/run \
            --with-syslog \
            --with-quotas \
            --with-acl-support \
            --enable-cups \
            --with-ads \
            --with-shared-modules=idmap_ad
