[Samba] Reverse zones fail with secure updates

Hello,

     I'm using Samba 4.5.1 as a ADDC and the internal DNS. If I use 
'allow dns updates = secure' in my smb.conf. Only A records update. The 
applicable reverse zone fails to update. If I switch to using non secure 
updates both the A and the PTR records are updated. Is someone else able 
to confirm this behavior? Thanks.

[Samba] Reverse zones fail with secure updates

Hai James, 

What is the connection's DNS suffix of the pc?
And did you setup TLS in you samba? 


Look here, in the advanded tcp settings of the pc.  ( or ipconfig /all )

And is it ticked "Use this connections dns suffix in dns registration"
(In dhcp option 81.)

Or use Group policy editors. 
- Computer Configuration\Administrative Templates\Network\DNS Client
	-Connection Specific DNS Suffix: enabled, and set to your.domain.tld
	-Register DNS records with connection-specific DNS suffix: enabled
	-Register PTR Records: enabled
	-Dynamic Update: enabled

Or use static ips, then A and PTR are registered by the computer. 

Key is to remember, Windows uses the connection-specific DNS suffix to register
DNS records.


Greetz, 

Louis

I'll point out what I have set in my smb.conf

samba-tool testparm -v | grep tls

         ldap ssl = start tls
         tls cafile = tls/ca.pem
         tls certfile = tls/cert.pem
         tls crlfile          tls dh params file          tls enabled = Yes
         tls keyfile = tls/key.pem
         tls priority = NORMAL:-VERS-SSL3.0
         tls verify peer = ca_and_name
