dnssec-lookaside != auto

[Torinthiel]

Hello everyone,

I've recently updated bind to version 9.7.2_p3.

I've been using DLV before that, specifically dlv.isc.org, with two
entries in named.conf

options {
dnssec-lookaside . trust-anchor dlv.isc.org.;
};
trusted-keys{
[sometext]
};

and it was working fine.
However, on update I've wanted to try managed-keys. so changed
trusted-keys to managed-keys (and added initial key of course)

so the relevant part of config file now looks like this:

managed-keys {
dlv.isc.org. initial-key 257 3 5
"BEAAAAPHMu/5onzrEE7z1egmhg/WPO0+juoZrW3euWEn4MxDCE1+lLy2
brhQv5rN32RKtMzX6Mj70jdzeND4XknW58dnJNPCxn8+jAGl2FZLK8t+

QKtUdvNXDrYJDSHZws3xiRXF1Rf+al9UmZfSav/4NWLKjHzpT59k/VSt TDN0YUuWrBNh";
};


this has caused problem, every query caused error, no answers and these
log entries:

After some googling and finding
http://www.mail-archive.com/bind-users@lists.isc.org/msg06660.html
and even better
http://www.mail-archive.com/bind-users@lists.isc.org/msg05689.html

I've changed to dnssec-lookaside auto. Lo and behold, everything works fine.

However, this presents the following problems to me:
- managed keys does not work as advertised:
In bind manual (PDF downloaded from http://www.bind9.net/manuals), it's
said that managed-keys is similar to trusted-keys, but where key in
trusted-keys is static and trusted as long as it's in config file, key
in managed-keys is trusted only once, to download this key and store it
in trusted database. This proves to be wrong, as it's not trusted even
that one time.

- I don't seem to be able to switch to another DLV registry.
dnssec-lookaside accepts only auto, so I have no choice but to use
built-in DLV. But, e.g. secspider.cs.ucla.edu looks interesting.

Can anyone shed some light if this is my mistake, not having something
in configuration, or a general bind error?
