Description of problem:
Running command ipa-replica-install --setup-dns --forwarder=xx.xx.xxx
failes to restart named, and coredumps

The trace is below:
It is crashing in bind, not sure if that is due to
bind-dyndb-ldap or not (it seems to be getting the data from ldap):

Core was generated by `/usr/sbin/named -u named'.
