It is a bit more complicated than that.
syncrepl is a client operation, which requires ldap client
configuration, specified in ldap.conf(5).
The sizelimit and timelimit, configuration parts defined in
slapd.conf(5), are global configuration parameters.
There is a database specific 'limits' parameter, which binds the
defined operation limitation to a Distinguished Name.
You realy should read that manual pages slapd.conf(5) and
slapd-config(5) on databasse limits and syncrepl limits.
