Not Authoritative for Zone

[Constantin Moldovan]

Hello,

I have to move the authority for the ofa.on.ca to our name servers:
ns1.broadband.net   and
ns2.broadband.net

The db.ofa.on.ca file looks like that:

@               IN      SOA     ns1.broadband.net. root.ns1.broadband.net.
( 2000082815  			10800 3600 60480 6400 )

                IN      NS      ns1.broadband.net.
                IN      NS      ns2.broadband.net.
                IN      A       206.222.77.162
                IN      MX      10 maildepot.ofa.on.ca.
                IN      MX      20 granite.sentex.ca.
maildepot       IN      A       206.222.77.162
localhost       IN      A       127.0.0.1
www             IN      A       206.222.77.162

The problem is that ns1.broadband.net doesn't seem to be authoritative for
the zone:

mailhost.gt.ca:/etc/named.d/primary# nslookup
Default Server:  mailhost.gt.ca
Address:  0.0.0.0

> set type=any
> ofa.on.ca
Server:  mailhost.gt.ca
Address:  0.0.0.0

Non-authoritative answer:
ofa.on.ca       nameserver = ns1.broadband.net
ofa.on.ca       nameserver = ns2.broadband.net
ofa.on.ca
        origin = ns1.broadband.net
        mail addr = root.ns1.broadband.net
        serial = 2000082815
        refresh = 10800 (3 hours)
        retry   = 3600 (1 hour)
        expire  = 60480 (16 hours 48 mins)
        minimum ttl = 6400 (1 hour 46 mins 40 secs)
ofa.on.ca       preference = 10, mail exchanger = maildepot.ofa.on.ca
ofa.on.ca       preference = 20, mail exchanger = granite.sentex.ca
ofa.on.ca       internet address = 206.222.77.162

Authoritative answers can be found from:
ns1.broadband.net       internet address = 207.107.209.130
ns2.broadband.net       internet address = 209.17.128.34
maildepot.ofa.on.ca     internet address = 206.222.77.162
granite.sentex.ca       internet address = 199.212.134.1
> ns1.gt.ca
Server:  mailhost.gt.ca
Address:  0.0.0.0

ns1.gt.ca       internet address = 207.107.209.130
gt.ca   nameserver = ns2.broadband.net
gt.ca   nameserver = ns1.broadband.net
ns2.broadband.net       internet address = 209.17.128.34
ns1.broadband.net       internet address = 207.107.209.130

When I try a zone transfer from ns1.broadband.net I get also:

Aug 29 06:20:45 named-xfer[10820]: [207.107.209.130] not authoritative for
ofa.on.ca, SOA query got rcode 0, aa 0, ancount 1, aucount 0

Any help will be appreciated.

Thank you,
Constantin
