I setup DNS as backend which is running under the same server.

I have done my test like the wiki and works.

host -t SRV _ldap._tcp.MBX.LOCAL.
_ldap._tcp.MBX.LOCAL has SRV record 0 100 389 mbxdc1.mbx.local.

host -t SRV _kerberos._udp.MBX.LOCAL.
_kerberos._udp.MBX.LOCAL has SRV record 0 100 88 mbxdc1.mbx.local.

 host -t A MBXDC1.MBX.LOCAL.
MBXDC1.MBX.LOCAL has address 192.168.1.5

But if I query a client won't answer:

host -t A MBX-TEST1.MBX.LOCAL.
Host MBX-TEST1.MBX.LOCAL. not found: 3(NXDOMAIN)

I have run

samba_dnsupdate --verbose

But don't see my  clients.

What else do I need to allow bind to record my clients?

Looks like I had follow the wiki all the way.

In what stage does bind record the new machine?

Thanks for your help.
