Re: Delta-syncrepl problem

I'm attempting to setup a delta-syncrepl replication scheme to replace
an aging slurpd installation and am having troubles. After trying
about 4 different tutorials and going through the docs this is almost
working. When bringing up a new ldap slave, it copies the database
down from the provider and seems to mirror it locally. When making
additions to the master, they do not replicate down to the slaves.

I suggest you go and re-read the documentation. There are multiple errors in your setup. See comments below for errors in the master configuration.

database       hdb
directory      /var/lib/ldap
suffix         cn=accesslog
rootdn         cn=accesslog
index default eq
index entryCSN,objectClass,reqEnd,reqResult,reqStart

Where's the syncprov overlay on the accesslog DB?


database        hdb
suffix          "o=mtt"
directory       /var/lib/ldap
rootdn          "cn=Manager,o=mtt"
rootpw          <SHA1 HASH HERE>

Where are your required indices? for this database?


overlay syncprov
syncprov-nopresent TRUE
syncprov-reloadhint TRUE

The above two statements do *not* go in the main DB.


syncprov-checkpoint 1000 60

Just this one does.

overlay accesslog
logdb cn=accesslog
logops writes
logsuccess TRUE
logpurge 07+00:00 01+00:00

This looks correct.
