[Samba] samba_dnsupdate error

[Jeanderson Soares]

Hi,

I replicated a new samba 4.5.0 from a samba 4.4.4 (the process took about 5
hours, against 20 hours when replicating a new 4.4.4, thanks!)
Everything went well, but I noticed that the dns updates are getting crashs
in the new server. See:

# samba_dnsupdate --verbose
[...]
25 DNS updates and 0 DNS deletes needed
ldb_wrap open of secrets.ldb
Traceback (most recent call last):
  File "/usr/local/sbin/samba_dnsupdate", line 784, in <module>
    creds = get_credentials(lp)
  File "/usr/local/sbin/samba_dnsupdate", line 141, in get_credentials
    ans = check_one_dns_name(sub_vars['DNSDOMAIN'] + '.', 'NS')
  File "/usr/local/sbin/samba_dnsupdate", line 251, in check_one_dns_name
    ans = resolver.query(name, name_type)

thanks for any help. Please tell me if more information is needed.
