[Samba] DHCP update registration DNS Bind9

[Ricardo Pardim Claus]

Dear Rowland, 
I appreciate the initial contact and the hint that you sent. 
I followed the tips presented in the wiki Samba and implemented the script on Centos 7. 
Apparently it's working. I'll wait for the next hours work, to make sure it worked. 

I have doubts: 
  - It is possible to manually perform the update script DNS? I tried to manually run but could not. 

  - Dhcpd that will be in charge of running the script every time the transactions (commit, release and expiry) are taken? 

  - In my smb.conf I had added the following lines. I must or can discard? This is the primary smb.conf DC where the DHCP + Bind9 is: 

kerberos method = system keytab 
client ldap sasl wrapping = sign 
allow dns updates = nonsecure and secure 
nsupdate command = /usr/bin/nsupdate -g 

Thank you!
