I have set up a slave ldap server for syncrepl and seem to be unable to get it to repicate. There is nothing logged on the slave at all. ACL logging on the master shows the slave connecting and seeming to get access - see below.

On the MAIN SERVER I HAVE 
access to attrs=userPassword,shadowLastChange
        by self =xw
        by anonymous auth
by dn="cn=sync,dc=my company,dc=com" read
        by * none

access to *
         by self write
by dn="cn=sync,dc=my company,dc=com" read
         by users read
         by * read


# Replication stuff
overlay syncprov
syncprov-checkpoint 100 10
syncprov-sessionlog 200

ON THE SLAVE I HAVE
access to *
 by self write
 by dn="cn=sync,dc=my company,dc=com" write
 by users read
 by anonymous auth

loglevel sync config acl 
logfile /tmp/ldaptmp
