       Hello,

I have troubles using openldap replication in Centos 6.4. and Centos 5.3

I have two server with following version of openldap from centos repository configures as multimaster replication (internal servers):

openldap-servers-2.4.23-32.el6_4.1.x86_64

openldap-clients-2.4.23-32.el6_4.1.x86_64

openldap-2.4.23-32.el6_4.1.x86_64

Then I have one external server with following products:

openldap-servers-2.3.43-12.el5_5.3

openldap-clients-2.3.43-12.el5_5.3

openldap-2.3.43-12.el5_5.3

Then two internal servers are configured as multi-master replication and everything is working fine. The external server is configures as slave replication from one of those internal servers using the following configuration:

CODE: SELECT ALL

database        bdb

suffix          "o=test,c=cz"

rootdn          "cn=Manager,o=test,c=cz"

directory       /var/local/ldap/test.cz

index entryCSN,entryUUID                eq

index objectClass                       eq,pres

index ou,cn,mail                        eq,pres,sub

syncrepl rid=132

  provider=ldaps://xxxxx.xxx.xxx

  type=refreshOnly

  interval=00:00:01:00

  searchbase="o=test,c=cz"

  filter="(!(objectclass=simpleSecurityObject))"

  scope=sub

  updatedn="cn=SyncMaster,o=test,c=cz"

  bindmethod=sasl

There is a problem with replication from internal server to external. If I delete the database of external server and start the consumer, everything is correctly replicated from the provider (internal server) to the consumer. Therefore I assume, that the replication is configured correctly. But if the servers are running for a while and changes are made on the Provider (internal server) some data are not replicated to the consumer. More precisely the contextCSN of the root of the tree of consumer (external server) is updated and is  the same as on the Provider(internal server), but some entries lower in the three are not replicated correctly, both the entry entryCSN and the entry data itself are not updated on the Consumer.

Do you have any idea where could be the problem?

Thank you,
