The {{EX:provider}} parameter specifies the replication provider site
containing the master content as an LDAP URI. The {{EX:provider}}
master replica will generate {{EX:searchResultEntry}} to the consumer slapd
as the search responses to the persistent synchronization search.
+If an error occurs during replication, the consumer will attempt to reconnect
+according to the retry parameter which is a list of the <retry interval>
+and <# of retries> pairs. For example, retry="60 5 300 3" lets the consumer
+retry every 60 seconds for the first 10 times and then retry every 300 seconds
+for the next three times before stop retrying. + in <# of retries> means

The schema checking can be enforced at the LDAP Sync consumer site
by turning on the {{EX:schemachecking}} parameter.
If it is turned on, every replicated entry will be checked for its
