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

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

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

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

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