Oh, forgot to mention...  if you dont already have it setup, you need an
olcRootDN and olcRootPW in the config database that matches the binddn
and credentials directives for olcSyncRepl.  i happen to use cn=config
for the config database, and cn=Manager,dc=bpk2,dc=com for the DIT
binddn's.  credentials should be the password used for auth.  the
password can be different for the config database vs the DIT, but within
each they should match.
