Ticket #319 - ldap-agent crashes on start with signal SIGSEGV
Bug Description: If you have two or more slapd instances defined in
ldap-agent.conf file, the agent will crash at startup.
Fix Description: When using openldap, we were not reseting the buffer
length between dse.ldif files. So we end passing in a
huge buffer length for the first line of the new file,
which leads to invalid memory being read later on.
