ldapmodify add olcSyncrepl (okey but not okey)

hi everyone

I'm must be doing something trivially wrong and am hoping someone could 
help.

I'm trying to add second replica:

$ ldapmodify -vv -h rider.my.dom:1389 -D "cn=admin,cn=config" -w 
my.Biotec13 -x
ldap_initialize( ldap://rider.my.dom:1389 )
dn: olcDatabase={1}bdb,cn=config
changetype: modify
add: olcSyncrepl: rid=002 provider=ldap://swir.my.dom:1389 
bindmethod=simple timeout=0 network-timeout=0 
binddn="uid=replicator,ou=people,dc=my,dc=dom" credentials="lejek9090" 
keepalive=0:0:0 starttls=no filter="(objectclass=*)" 
searchbase="dc=my,dc=dom" scope=sub attrs="*,+" schemachecking=off 
type=refreshOnly interval=00:00:10:00 retry="5 5 300 +"

exit code of the above to shell is 0 yet next ldapsearch finds no such 
new entry exists.

At the time of ldapmodify in logs I see:

Nov 19 14:40:48 rider slapd[90048]: slap_queue_csn: queueing 
0x7f22cc111e00 20181119144048.167126Z#000000#005#000000

0x7f22cc111e00 20181119144048.167126Z#000000#005#000000

How to get it work?

Many thanks, L.
