[Samba] CTDB upgrade to SAMBA 4.8.3

[Micha Ballmann]

I'm sorry you're right:

my "local" smb.conf on each client:

[global]
  clustering = yes
  include =registry

net conf list (output registry):

[global]
         security = ads
         netbios name = sambacluster
         realm = DOMAINNAME.de
         workgroup = DOMAINNAME
         idmap config *:backend = tdb
         idmap config *:range = 3000-7999
         idmap config domainname:backend = ad
         idmap config domainname:range = 10000-999999
         idmap config domainname:schema_mode = rfc2307
         idmap config domainname: unix_nss_info = no
         domain master = no
         local master = no
         preferred master = no
         os level = 0
         restrict anonymous = 2
         winbind cache time = 10
         winbind enum groups = yes
         winbind enum users = yes
         winbind use default domain = yes
         map acl inherit = yes
         store dos attributes = yes
         vfs objects = acl_xattr
         username map = /usr/local/samba/private/user.map

[home]
         path = /cephfuse/samba/homedir/
         read only = no

[profiles]
         path = /cephfuse/samba/profiles
         read only = no
         browseable = no

[chickenwings]
         path = /cephfuse/samba/chickenwings
         read only = no
         browseable = no
