i dont think you are loading the module correctly. adjust the olcModulePath to your needs:

dn: cn=module,cn=config changetype:add objectClass: olcModuleList cn: module olcModulePath: /usr/lib64/openldap olcModuleLoad: syncprov.la

what i have used to get my n-way working for cn=config, adjust to your needs:

dn: olcOverlay=syncprov,olcDatabase={0}config,cn=config changetype: add objectClass: olcOverlayConfig objectClass: olcSyncProvConfig olcOverlay: syncprov

dn: olcDatabase={0}config,cn=config changetype: modify add: olcSyncRepl olcSyncRepl: rid=001 provider=ldap://ldap1.bpk2.com binddn="cn=config" bindmethod=simple credentials=secret searchbase="cn=config" type=refreshAndPersist retry="5 5 300 5" timeout=1 olcSyncRepl: rid=002 provider=ldap://ldap2.bpk2.com binddn="cn=config" bindmethod=simple credentials=secret searchbase="cn=config" type=refreshAndPersist retry="5 5 300 5" timeout=1 - add: olcMirrorMode olcMirrorMode: TRUE

then for the DIT itself, adjust to your needs:

dn: olcDatabase={2}hdb,cn=config changetype: modify add: olcLimits olcLimits: dn.exact="cn=Manager,dc=bpk2,dc=com" time.soft=unlimited time.hard=unlimited size.soft=unlimited size.hard=unlimited - add: olcSyncRepl olcSyncRepl: rid=001 provider=ldap://ldap1.bpk2.com binddn="cn=Manager,dc=bpk2,dc=com" bindmethod=simple credentials=secret searchbase="dc=bpk2,dc=com" scope=sub schemachecking=off type=refreshAndPersist interval=00:00:00:10 retry="5 5 300 5" timeout=1 olcSyncRepl: rid=002 provider=ldap://ldap2.bpk2.com binddn="cn=Manager,dc=bpk2,dc=com" bindmethod=simple credentials=secret searchbase="dc=bpk2,dc=com" scope=sub schemachecking=off type=refreshAndPersist interval=00:00:00:10 retry="5 5 300 5" timeout=1 - add: olcMirrorMode olcMirrorMode: TRUE - dn: olcOverlay=syncprov,olcDatabase={2}hdb,cn=config changetype: add objectClass: olcOverlayConfig objectClass: olcSyncProvConfig olcOverlay: syncprov

you should turn up the sync log level to make sure you see the replication logs, too. it has helped me. i only turned on sync, you might want stats, stats2, etc:

dn: cn=config changetype: modify replace: olcLogLevel olcLogLevel: sync

hope that helps.

Hi,

When I configure N-Way Multi-Master configuration with cn=config, slapd terminates with the error: "module syncprov.la: null module registered" and "read_config: no serverID / URL match found. Check slapd -h arguments". olcServerID IDs are already added and configured properly, but when slapd starts with -h option, it always fails.

Please help if someone has gone through a similar issue. Thanks, Joe

Reference, Step 3-4: http://niranjanmr.wordpress.com/2012/03/29/n-waymmr/ Is there an equivalent /etc/sysconfig/ldap file in Solaris 10?
