[Samba] Permission Issue

[Benedikt Kaleß]

Hi,

I don't have the user root.

No changes :( Sometimes a user gets permissions, sometimes not.

This net conf is now running:

[global]
    winbind refresh tickets = Yes
    winbind use default domain = yes
    template shell = /bin/bash
    idmap config * : range = 1000000 - 1999999
    idmap config EXAMPLE : backend = rid
    idmap config EXAMPLE : range = 500 - 200000
    hide dot files = yes
    server string = FileServer %h (Samba %v)
    map acl inherit = yes
    inherit permissions = yes
    workgroup = ZFD
    netbios name = CLUSTER-HO
    clustering = yes
    security = ads
    realm = EXAMPLE.com
    store dos attributes = Yes
    log level = 3
    vfs objects = acl_xattr

[home]
    comment = Home Directories
    read only = no
    browseable = yes
    vfs objects = acl_xattr glusterfs
    glusterfs:volume = gv-ho
    glusterfs:logfile = /var/log/samba/glusterfs-gv-ho.log
    glusterfs:loglevel = 3
    glusterfs:volfile_server = gluster1 gluster3
    kernel share modes = no
    path = /

[Fileshare]
    comment = Fileshare
    read only = no
    vfs objects = acl_xattr glusterfs
    glusterfs:volume = gv-ho
    glusterfs:logfile = /var/log/samba/glusterfs-gv-ho.log
    glusterfs:loglevel = 10
    glusterfs:volfile_server = gluster1 gluster3
    kernel share modes = no
    path = /data/Files

Does this error in log.smbd give a hint?
