[Bug 1585111] Re: net rpc join fails in Ubuntu 16.04

[Hubert Higelin]

I tried with the parameters indicated by @metze in # 13. I made a second
attempt by adding allow nt4 crypto = Yes. Both attempts failed. Attached
is the copy of the testparm and net rpc join outputs of the first
attempt. The outputs for the second attempt are similar.

Title:
  net rpc join fails in Ubuntu 16.04

Status in samba package in Ubuntu:
  Expired

Bug description:
  Trying to join a machine to a domain.

  This worked well in 12.04

  smb.conf
  [global]
  security = domain
  netbios name = LD7vb2
  realm = DOMAIN.COM
  # originally we had "password server" but this is the recommended setting
  wins server = ipbrick.DOMAIN.COM
  workgroup = DOMAIN
  # programatic UID calculation to make UIDs uniform accross machines
  idmap config * : range = 2000-302000
  idmap config * : base_rid = 0
  idmap config * : backend = rid
  winbind separator = +
  winbind enum users = yes
  winbind enum groups = yes
  winbind use default domain = yes
  #template homedir = /home/%D/%U
  # WA folderview vs long paths
  template homedir = /home/%U
  template shell = /bin/bash
  client use spnego = yes
  domain master = no

  Cant use it on Ubuntu 16.04

  doing: net rpc join -U administrator
  Result:
  No realm has been specified! Do you really want to join an Active Directory server?
  Enter administrator's password:
  smb_signing_good: BAD SIG: seq 1
  Failed to join domain: failed to lookup DC info for domin 'DOMAIN' over rpc: Access denied.

  
  Can use: smbclinet -L ipbrick -U administrator and see infos about the server.

  What can I do to join my machine to a domain with "net rpc join"?
