replication questions

Hello I am trying to replicate data between 2 systems, but it doesn't seems to be working.I can loginto slave system you the uid I am trying to bind.

replica host=pcNavYkfSupp1.ykf.navtechinc.com:389
        binddn="cn=replica,ou=ykfPeople,dc=navtechinc,dc=com"
        bindmethod=simple credentials=replica
#        tls=yes
#replogfile /var/log/slapd.replog
replogfile /var/lib/ldap/replica/slurpd.replog

updatedn "cn=replica,ou=ykfPeople,dc=navtechinc,dc=com"
updateref "ldap://pcNavYkfSupp2.navtechinc.com"

#This is ACL (Access Control List) for Slapd

access to dn=".*,dc=navtechinc,dc=com" attr=userPassword,ntPassword,lmPassword
        by dn="cn=Manager,dc=navtechinc,dc=com" write
        by dn="cn=replica,ou=ukfPeople,dc=navtechinc,dc=com" write
        by self write
        by * auth

access to dn=".*,dc=navtechinc,dc=com" attr=mail
        by dn="cn=Manager,dc=navtechinc,dc=com" write
        by self write
        by * read

#access to dn=".*,dc=navtechinc,dc=com"
# by dn="cn=replica,dc=navtechinc,dc=com" write

#access to dn=".*,ou=ykf,dc=navtechinc,dc=com"

This is slapd.log on SLAVE , where I can see slurpd, is hitting hard to replicate changes, but

Does this thing rings the bell

Here is how my cn-replica looks like on SLAVE
