AXFR query fail with LDAP backend

[anon]

Hi We are using PowerDNS 2.9.22 (from lenny backport) with a LDAP backend.

Trying to make an AXFR query on the zone fails:

  dig @dns logilab.fr AXFR
  ; <<>> DiG 9.6.1-P1 <<>> @localhost -p 5300 logilab.fr AXFR
  ; (2 servers found)
  ;; global options: +cmd
  logilab.fr.             3600    IN      SOA       ns.logilab.fr. hostmaster.logilab.fr. 2010030202 28800 14400 3600000 86400
  ;; Got bad packet: out of range
  2352 bytes
  [SNIP hex dump of the 2352 bytes]

Meanwhile the pdns monitor reports the following error:

  Apr 30 21:34:26 AXFR of domain 'logilab.fr' initiated by 127.0.0.1
  Apr 30 21:34:26 [LdapBackend] LDAP servers = ldap://192.168.1.248/ ldap://192.168.1.247/

We are unable to address LDAP issues at this time.
