Hi There, We are in the middle of implementing OpenLDAP into our network. We are testing our implementation and facing the below error in our logs after a node has either been powered off or the slapd service has been stopped (and subsequently brought back online):
syncprov_sendresp: cookie=rid=001,sid=001,csn=20200813144529.184309Z#000000#001#000000 do_syncrep2: rid=002 got search entry without Sync State control (dc=domain,dc=local) do_syncrepl: rid=002 rc -1 retrying syncprov_sendresp: cookie=rid=001,sid=001,csn=20200813144529.378496Z#000000#001#000000 This error is only encountered on the node that had been brought offline. Prior to this replication had/has been working without issue - as far as we can tell. Below are the configuration LDIFs we used to enable replication: dn: cn=config changetype: modify add: olcServerID olcServerID: 1 ldap://ldap1.domain.local/ olcServerID: 2 ldap://ldap2.domain.local/ dn: cn=module{0},cn=config changetype: modify add: olcModuleLoad olcModuleLoad: syncprov.la dn: olcOverlay=syncprov,olcDatabase={3}mdb,cn=config objectClass: olcOverlayConfig objectClass: olcSyncProvConfig olcOverlay: syncprov dn: olcDatabase={3}mdb,cn=config changetype:modify add: olcSyncrepl olcSyncrepl: rid=001 provider=ldap://ldap1.domain.local/ binddn="cn=manager,dc=domain,dc=local" bindmethod=simple credentials=ldap_pw searchbase="dc=domain,dc=local" type=refreshAndPersist retry="5 5 300 +" timeout=1 olcSyncrepl: rid=002 provider=ldap://ldap2.domain.local/ binddn="cn=manager,dc=domain,dc=local" bindmethod=simple credentials=ldap_pw searchbase="dc=domain,dc=local" type=refreshAndPersist retry="5 5 300 +" timeout=1 - add: olcMirrorMode olcMirrorMode: TRUE I have seen other posts about this error that mention the overlay not being properly configured, however, I don't think this is the case for us since replication does work as expected until a node is brought offline. It also seems that any changes made to online nodes are not replicated to the offline node when it is brought back online. However, any changes made after that node has been brought back online are replicated. I am sure this is probably a configuration issue but not sure where to go from here. Any help is greatly appreciated. Thanks!
