Univention Bugzilla – Bug 33707
DNS with LDAP backend doesn't start if zone has incorrect nameserver
Last modified: 2018-04-13 13:32:34 CEST
Reported by a customer, maybe related/duplicate to Bug #28363: If the "nameserver"-entry of a zone contains a non existing FQDN (in the reported case the customer deleted the UDM object of a UCS DC and it's A-record), the zone transfer fails. Once BIND is stopped (maybe by logrotate) it doesn't start anymore until the wrong entry is removed. Systems with Samba4 backend are working fine.
BIND refuses to load/transfer a broken zone, e.g. a zone which has NS RRs which BIND can't resolve to an A/AAA address. See <http://sdb.univention.de/content/20/254/en/bind-zone-transfer-failed.html> *** This bug has been marked as a duplicate of bug 28363 ***
