Re: OpenLDAP 2.4 syncrepl - Size limit exceeded error in consumer end



Hi Buchan,

Thanks for your response. I will test my configuration manually. May be I would have overlooked some of the configuration directives.

Thanks & Regards,
Karthik Dathathri

I was trying to setup replication using syncrepl with openldap 2.4.11
on two machines running RHEL 5.0

The provider has approximately 1000 entries in the directory.

On the consumer side, I am getting the following error after
synchronization of around 500 records.

Oct 14 16:35:59 osmvm2 slapd2.4[11727]: syncrepl_entry: rid=001

LDAP_RES_SEARCH_RESULT
Oct 14 16:35:59 osmvm2 slapd2.4[11727]: do_syncrep2: rid=001 (4) Size
limit exceeded

I am using "refreshOnly" syncrepl in the consumer.

The syncrepl user dn is uid=syncrepl,ou=System,dc=example,dc=com

and added this dn as a member to a group called LDAPAdmins
(cn=LDAPAdmins,ou=Groups,dc=example,dc=com)

slapd.conf configuration at the consumer end is as follows:

This is irrelevant, searches are done against the provider, not the consumer.



# Replicas running syncrepl as non-rootdn need unrestricted size/time limits: limits group="cn=LDAPAdmins,ou=Groups,dc=example,dc=com" size=unlimited time=unlimited

#SyncRepl slave configuration
syncrepl rid=001
    provider=ldap://16.167.10.25
    type=refreshOnly
    interval=00:00:05:00
    searchbase="dc=example,dc=com"
    binddn="uid=syncrepl,ou=System,dc=example,dc=com"
    credentials=secret
    timelimit=unlimited
    sizelimit=unlimited

slapd.conf configuration at the provider is as follows:

#Global ACL for replication
access to *
        by group="cn=LDAPAdmins,ou=Groups,dc=example,dc=com" read
        by anonymous read

So, access to * by * read would work, and you can't be sure that your group is
working from the ACLs ....



# syncprov index entryCSN,entryUUID eq

# Replicas running syncrepl as non-rootdn need unrestricted size/time
limits:
limits group="cn=LDAPAdmins,ou=Groups,dc=example,dc=com"
 size=unlimited
 time=unlimited

So, if you do a search as your uid=syncrepl DN (with ldapsearch), how many
entries do you get, and what result code do you get?

# ACL ensuring replicator has write access

Syncrepl does not require that any replication DN has write access anywhere
...


access to *
        by group="cn=LDAPAdmins,ou=Groups,dc=example,dc=com" write
        by * read

#syncprov overlay configuration
overlay syncprov
syncprov-checkpoint 50 10
syncprov-sessionlog 100

Any pointers would be appreciated. If someone needs more information
about the environment, please
let me know.

It;s possible to test some of your configuration manually, which I would
normally do *first* (before configuring the consumer).

Buchan
