I have setup samba 4 as File Server Member Server, But when the users, even
logged in the domain, click on the share, a box appears asking for
authentication and the authentication failure.

The member server is in the domain, it see the users and groups (wbinfo –u
and wbinfo –g), the Kerberos show ticket (klist) for administrator user
I use Debian 7.2 – 64 bits, on Citrix XenServer with the Samba 4.2.2

All the configurations seem OK.

this is my smb.conf:

  netbios name = arquivos
  workgroup = MEUDOMINIO
  security = ADS
  realm = MEUDOMINIO
  encrypt passwords = yes

  idmap config *:backend = tdb
  idmap config *:range = 70001-80000
  idmap config MEUDOMINIO:backend = ad
  idmap config MEUDOMINIO:schema_mode = rfc2307
  idmap config MEUDOMINIO:range = 3000000-4000000

  winbind nss info = rfc2307
  winbind trusted domains only = no
  winbind use default domain = yes
  winbind enum users = yes
  winbind enum groups = yes

  vfs objects = acl_xattr
  map acl inherit = Yes
  store dos attributes = Yes
  username map = /etc/samba/user.map

 path = /Compartilhamentos/Arquivos
 read only = no

Does somebody have an idea?
