N-Way Multi-Master replication - delete problem - openldap-technical

22 Dec 2008


      OK, But then what did I do wrong ? delete an entry shouldn't be a problem with N-Way Multi-Master replication ? should it ?
Here is how I have setup-ed my masters :
m1 -config :
dn: cn=config
objectClass: olcGlobal
cn: config
olcServerID: 1
dn: olcDatabase={0}config,cn=config
objectClass: olcDatabaseConfig
olcDatabase: {0}config
olcRootPW:< file://$CONFIGPWF
m2 - config :
dn: cn=config
objectClass: olcGlobal
cn: config
olcServerID: 2
dn: olcDatabase={0}config,cn=config
objectClass: olcDatabaseConfig
olcDatabase: {0}config
olcRootPW:< file://$CONFIGPWF
m1 - syncprov :
dn: cn=config
changetype: modify
replace: olcServerID
olcServerID: 1 $URI1
olcServerID: 2 $URI2
dn: olcOverlay=syncprov,olcDatabase={0}config,cn=config
changetype: add
objectClass: olcOverlayConfig
objectClass: olcSyncProvConfig
olcOverlay: syncprov
dn: olcDatabase={0}config,cn=config
changetype: modify
add: olcSyncRepl
olcSyncRepl: rid=001 provider=$URI1 binddn="cn=config" bindmethod=simple
  credentials=$CONFIGPW searchbase="cn=config" type=refreshAndPersist
  retry="5 5 300 5" timeout=3
olcSyncRepl: rid=002 provider=$URI2 binddn="cn=config" bindmethod=simple
  credentials=$CONFIGPW searchbase="cn=config" type=refreshAndPersist
  retry="5 5 300 5" timeout=3
-
add: olcMirrorMode
olcMirrorMode: TRUE
m2 - syncrepl :
dn: olcDatabase={0}config,cn=config
changetype: modify
add: olcSyncRepl
olcSyncRepl: rid=001 provider=$URI1 binddn="cn=config" bindmethod=simple
  credentials=$CONFIGPW searchbase="cn=config" type=refreshAndPersist
  retry="5 5 300 5" timeout=3
olcSyncRepl: rid=002 provider=$URI2 binddn="cn=config" bindmethod=simple
  credentials=$CONFIGPW searchbase="cn=config" type=refreshAndPersist
  retry="5 5 300 5" timeout=3
-
add: olcMirrorMode
olcMirrorMode: TRUE
m1 - schema :
include: file://$ABS_SCHEMADIR/core.ldif
include: file://$ABS_SCHEMADIR/cosine.ldif
include: file://$ABS_SCHEMADIR/inetorgperson.ldif
include: file://$ABS_SCHEMADIR/openldap.ldif
include: file://$ABS_SCHEMADIR/nis.ldif
m1 - backend :
dn: olcDatabase={1}$BACKEND,cn=config
objectClass: olcDatabaseConfig
objectClass: olc${BACKEND}Config
olcDatabase: {1}$BACKEND
olcSuffix: $BASEDN
olcDbDirectory: ./openldap-data
olcRootDN: $MANAGERDN
olcRootPW: $PASSWD
olcSyncRepl: rid=004 provider=$URI1 binddn="$MANAGERDN" bindmethod=simple
  credentials=$PASSWD searchbase="$BASEDN" type=refreshOnly
  interval=$INTERVAL retry="5 5 300 5" timeout=3
olcSyncRepl: rid=005 provider=$URI2 binddn="$MANAGERDN" bindmethod=simple
  credentials=$PASSWD searchbase="$BASEDN" type=refreshOnly
  interval=$INTERVAL retry="5 5 300 5" timeout=3
olcMirrorMode: TRUE
dn: olcOverlay=syncprov,olcDatabase={1}${BACKEND},cn=config
changetype: add
objectClass: olcOverlayConfig
objectClass: olcSyncProvConfig
olcOverlay: syncprov
Did I miss something ? 
Has anyone tested N-way Multi-master replication & encountered the same problem as me ?

Hy everyone,
I have just tested the same procedure with OpenLDAP 2.4.13. The problem
remains the same.
Did I miss something ? Is this supposed to be like this ?
I'm joining the modified script I'm using to setup both masters and the
LDIF files I'm using to add and remove an entry (+ attributes).
I did not use access-log, is this supposed to work with N-Way
Multi-Master replication ? I thought it was only used in case of Delta
Synchronization/Replication.
Correct, delta-syncrepl and MMR are not currently supported together (that 
 may change in the future).
