If the root of the primary database is "", and you try and export a base that
doesn't exist via slapcat, the entire database is exported (i.e., it acts like
you specified "" as the base):

[root@zcs724 ldap]# /opt/zimbra/openldap/sbin/slapcat -b cn=ThisDoesntExist -F
/opt/zimbra/data/ldap/config -l /tmp/q.test
