         realm = XXX.XXX.XX
         netbios name = XXXX
         log file = /var/log/samba/%m
         log level = 1
         idmap config * : backend = tdb
         idmap config * : range = 10000-10100
         idmap config XXX:backend = rid
         idmap config XXX:range = 1000000-1999999
         vfs objects = acl_xattr
         map acl inherit = yes
         inherit acls = yes
         store dos attributes = yes
         winbind use default domain = yes
         template shell = /bin/bash

         shadow:basedir = /srv/glvol_samba/admin/projects
         shadow:sort = desc
         vfs objects = acl_xattr shadow_copy2 glusterfs_fuse
         acl_xattr:ignore system acls = yes
         shadow:format = _GMT-%Y.%m.%d-%H.%M.%S
         shadow:snapprefix = snapSC



gluster mount unit:
