[Samba] Samba4, DHCP, & BIND DLZ

[Jeff]

Hello,

I have recently compiled, installed and configured samba4 to run on a FreeBSD server.

samba -V reports the version to be Version 4.1.0pre1-GIT-57990cb.

The server has working BIND 9.9 and ISC-DHCP services running on it.  

I have provisioned samba 4 to use the BIND_DLZ DNS backend.  

On the whole things seem to be working.  local names are being resolved.  phpLDAPAdmin shows the new AD.

I need to resolve a couple of things though.

(1) log.samba has a lot of

[2012/09/20 15:41:08,  0] ../lib/util/util_runcmd.c:334(samba_runcmd_io_handler)

 /usr/local/samba/sbin/samba_dnsupdate: response to GSS-TSIG query was unsuccessful

What does it mean and how do I fix it??


(2) I need to ensure that DHCP is playing nicely with samba4.  How are DNS updates from the DHCP server propagated to samba4??  I've changed my BIND so that it no longer uses zone files for the local domain.  Instead it uses the bind9 dlz driver that came with samba4.  If I understand correctly, this means that bind will now pass queries about the local domain off to samba.  So samba must be updated whenever a new DHCP lease is granted by the dhcp server.  Does the DLZ driver handle this, or does the DHCP server need to be configured to cause these updates to go directly to samba??


Thanks,
Jeff
