[Samba] [samba] Member server winbind issue




Hi all,

I'm trying to set up a Samba file server authenticating against Samba AD
domain and I'm facing an issue configuring winbind:
- wbinfo -n username works, it gives username's SID
- wbinfo -S <username's SID> works, it gives username's UID

but wbinfo -i username does not work:

wbinfo -i username
failed to call wbcGetpwnam: WBC_ERR_DOMAIN_NOT_FOUND
Could not get info for user username

log.winbindd gives:
[2017/07/23 01:27:01.433530,  6]

smb.conf is the following:
------------------------------------
[global]
  netbios name = SMBSRV
  realm = AD.INFRACTORY.ORG
  workgroup = AD

  security = ADS

  #log file = /var/log/samba/%m.log
  log level = 8

  kerberos method = dedicated keytab
  dedicated keytab file = /etc/krb5.keytab

  # Default ID mapping configuration for local BUILTIN accounts
  # and groups on a domain member. The default (*) domain:
  # - must not overlap with any domain ID mapping configuration!
  # - must use a read-write-enabled back end, such as tdb.
  # - Adding just this is not enough
  # - You must set a DOMAIN backend configuration, see below
  idmap config * : backend = tdb
  idmap config * : range = 1200-1499

  winbind nss info = rfc2307

  # idmap config for the AD domain
  idmap config AD:backend = ad
  idmap config AD:schema_mode = rfc2307
  idmap config AD:range = 1500-99999999
  idmap config AD:unix_primary_group = yes

  winbind use default domain = yes
------------------------------------
Currently no share is declared.

On both DC wbinfo -n, -S and -i are all working (no idea if it proves
anything)

Wishing you a great week-end,
