Thank you so much for everyone's help.

The fix for issue "read_config: no serverID / URL match found. Check slapd -h arguments" is the port number used in -h option. Fixed: slapd -d -1 -h "ldap://apggd04dev.pg.dtveng.net" Error: slapd -d -1 -h "ldap://apggd04dev.pg.dtveng.net:389"

Have a great day! Joe

Oh, forgot to mention...  if you dont already have it setup, you need an olcRootDN and olcRootPW in the config database that matches the binddn and credentials directives for olcSyncRepl.  i happen to use cn=config for the config database, and cn=Manager,dc=bpk2,dc=com for the DIT binddn's.  credentials should be the password used for auth.  the password can be different for the config database vs the DIT, but within each they should match.

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: 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
