Description Tim Petersen

We saw this in two customer environments...

somehow a corrupt alias record was created/modified

dn: relativeDomainName=._msdcs,zoneName=domain.de,cn=dns,dc=domain,dc=de

cNAMERecord: ucs-server.domain.de.
objectClass: top
objectClass: dNSZone
objectClass: univentionObject
univentionObjectType: dns/alias
dNSTTL: 80600
relativeDomainName: ._msdcs
zoneName: domain.de


This is no problem till you start using bind with ldap backend... the record corrupts the zone transfer.

Unfortunately I have no idea how this happend. In one case the corresponing server (where the cname records comes from) was rejoined - the recordname indicates that there was a problem with modifying the guid part perhaps...
