PLEASE READ: BIND 8.2.2 problem

I have run across an issue with BIND 8.2.2-P5 that I haven't been able to
resolve with an option in named.conf.

We run hosts2ns automatically to convert our NIS hosts file into DNS
zone DB files. Since we have such a large number of admins we sometimes
end up with CNAMES that have other data, getting the standard messages
from named:

Apr 27 14:05:51 ankokuji named[24446]: auto/synopsys.com:50225:iei.synopsys.com: 
CNAME and OTHER data error
Apr 27 14:05:51 ankokuji named[24446]: master zone "synopsys.com" (IN) rejected 
due to errors (serial 2000042756)

Under Bind 4.9.7 we would get the messages but named would still accept
the domain. Under Bind 8.2.2-P5 named rejects the domain and the server
quietly becomes non-authoritative for synopsys.com.

The result being that any changes made to the NIS hosts file do not get
into DNS and we cannot resolve them using nslookup until the error is fixed
in the NIS hosts file.

I have been looking for an option or something to tell BIND 8.2.2-P5 to
just throw out the bad record and not reject the domain. Seems silly to
reject the entire domain just because of one error.

Any ideas? I've been through the bind-users archive and "DNS and Bind v3"
without sucess.

Thanks,

Brian

PS Internal folks:

The way to fix this is always put the "real" name of the host first
in the hosts entry and then put the aliases (CNAMES) after it. For
example, the problem that created the above error message was caused
because "iei" has an MX record and had the bad entry below.

146.225.66.77   iei-e450 iei    # E450 Evaluation System/IEI Lab

Once I changed this to the following everything was working fine again.

146.225.66.77   iei iei-e450    # E450 Evaluation System/IEI Lab
