Dear Strahil,

please find my current settings below:


[global]
         netbios name = yourName
         workgroup = yourWorkgroup
         realm = YourRealm
         log file = /var/log/samba/log.%m
         max log size = 50
         security = ads

         clustering = yes

         max protocol = SMB3
          kernel share modes = no
          kernel change notify = no

         kernel oplocks = no
         posix locking = no

         map archive = no
         map hidden = no
         map read only = no
         map system = no
         store dos attributes = yes


         idmap config * : backend = autorid
         idmap config * : range = 1000000-19999999
         idmap config * : rangesize = 1000000
         include = /etc/samba/ctdb.conf
         fruit:aapl = yes
         ea support = yes

     # it turns out that using SMB1 via linux/rsync
     # is leading to wrong permissions in our case
     min protocol = SMB2

[gluster-replicated]
     comment =
     vfs objects = fruit streams_xattr glusterfs
     glusterfs:volume = yourGlusterVolume
     glusterfs:logfile = /var/log/samba/yourLog.log
     glusterfs:loglevel = 1
     inherit acls = yes
     path = /
     read only = no
     guest ok = no


Please let me know if this works for you.


Regards,

Felix

> When my client mounts the samba share via vers=1.0 , the user sees the share properly (uid,gid,mode are just like on gluster). When the share is mounted with vers=2.0 or not specified (anything higher) the files are owned by root/root and can't be changed (even by root).
