Re: slapd terminates with error "read_config: no serverID / URL match found. Check slapd -h arguments"

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.
