syncrepl - when master restarted, slaves loose connection forever (and never reconnects)?

[Tomasz Chmielewski <mangoo@wpkg.org>]

I decided to use syncrepl (refreshAndPersist) instead of slurpd to 
synchronize.

I made simple tests but something doesn't work right for me.


I started a totally empty OpenLDAP slave - it got replicated
from the master.
Any change made on the master is also replicated fine.


Unfortunately, when the connection between the slave and the master is 
broken (i.e., master restarted), the slave never reconnects. According 
to the fine slapd.conf manual, reconnection should be made quite fast:

 "If the connection is lost, the consumer will attempt to reconnect
 at an interval time (specified by interval parameter; 60 seconds by
 default) until the session is re-established."


I waited for about 12 hours, and it didn't happen.
Restarting slave helped, and all pending changes were transferred from 
the master.

Am I missing a setting or something?


The slave is running slapd from OpenLDAP 2.3.37, and here is its 
slapd.conf part concerning syncrepl:

syncrepl  rid=0
              provider=ldap://master:389
# interval=00:00:00:30  <- also didn't help if it's 30 secs
              type=refreshAndPersist
              searchbase="dc=some,dc=domain"
              bindmethod=simple
              binddn="cn=replicationuser,dc=some,dc=domain"
              credentials=secret
              schemachecking=off
