[Samba] samba4+bind9.9 will not start: samba_dlz: dns_rdata_fromtext: buffer-0x7f1c0cbcd680:1: near 'hostmaster.domain.de': not a valid number

Hello,

running on Debian jessie 64bit samba 4.0.8 and bind 9.9 but with the
description from https://wiki.samba.org/index.php/Dns-backend_bind I run
into the following problem:

# named -u bind -g 2>&1 |tee named.log

The smb.conf is:
[global]
   workgroup = domain
   realm = DOMAIN.DE
   netbios name = sso-test System
   server services = -dns
   wins support = yes
   log file = /var/log/samba/log.%m
   max log size = 1000
   syslog only = no
   syslog = 10
   panic action = /usr/share/samba/panic-action %d
   server role = domain controller
   passdb backend = tdbsam
   obey pam restrictions = yes
   unix password sync = yes
   pam password change = yes
   map to guest = bad user

[sysvol]
  path = /var/lib/samba/sysvol
  read only = no

[netlogon]
  path = /var/lib/samba/sysvol/domain.de/scripts
  read only = no

Enabling the internal samba DNS and it works. Kerberos things like kinit
and klist works.

Commenting the database "dlopen ... in private/named.conf out let the
bind server start but of course without the samba Zone.

Any idea what could be wrong or how can I debug the wrong zone?

Thank you.

Regards
	Noel

[Samba] [SOLVED] Re: samba4+bind9.9 will not start: samba_dlz: dns_rdata_fromtext: buffer-0x7f1c0cbcd680:1: near 'hostmaster.domain.de': not a valid number

Hello,

I solved my bind problem:

The netbios name was "sso-test System" (my failure to add a additional
and wrong space) with the result in the machine account "SSO-TEST SYSTEM
$@DOMAIN.DE" but the system name is just sso-test.

Comment out this option and reprovisioning solves my bind problem. Just
if somebody have the same problem.

Is it worth to file a bug to have the option checked?
