Note that there is a hard coded limit to 500 operations. If you have
more than 500 entries, syncrepl only recieves a limited set of entries.
Read slapd-config(5) on limits.

I feel this is somewhat contradictory with the admin guide:

"
The content of the syncrepl replica is
        defined using a search specification as its result set. The
        consumer slapd will send search requests to the provider slapd
        according to the search specification. The search specification
        includes 
searchbase
, 
scope
, 
filter
, 
attrs
, 
attrsonly
, 
sizelimit
, and 
timelimit
 parameters as
        in the normal search specification. The 
searchbase
 parameter has
        no default value and must always be specified. The 
scope
 defaults to 
sub
, the 
filter
 defaults to 
(objectclass=*)
, 
attrs
 defaults to 
"*,+"
 to replicate
        all user and operational attributes, and
attrsonly
 is unset by
        default. Both 
sizelimit
 and 
timelimit

default
        to "unlimited", and only positive integers or "unlimited" may be
        specified.
"

It 
specifies that the sizelimit and timelimit
        defaults to unlimited. I understand that you are pointing out a
        hard limit on the provider side so it doesn't matter that the
        search is unlimited from the consumer's side, it's just a first
        glance it seems that the search will be unlimited.

        Either way, I change both provider and consumer databases to
        unlimited and 
I'm still not
            getting all the database entries from my provider.
