Re: Replication appears to vanish, sometimes.

Here's a list of problems with your setup:

You are using an ancient version of OpenLDAP. 

Installed 2.3.41


You are using BDB 4.2.52 without the required patches. 

Installed 4.2.52 5 patches. (patch 3 failed, but appears java related)


You are using slurpd.
Use syncrepl instead of slurpd


Changed to syncrepl. But I do feel that the documentation could do with
a better example, one simpler. I would have thought that simply
replicating everything is a common desire, when the example is one much
more complicated.

These are the changes I made to master-slapd.conf (plus ./configure
--enable-lastmod) :

That --enable option isn't needed. It has nothing to do with the lastmod directive in slapd.conf.

lastmod on

As documented in slapd.conf(5), lastmod is already on by default. 

index   entryCSN,entryUUID      eq

overlay syncprov

syncprov-checkpoint 100 10
syncprov-sessionlog 100


These are the changes I made to slave-slapd.conf:

lastmod         on

index   entryCSN,entryUUID      eq


syncrepl   rid=1
                  provider=ldap://172.20.12.113
                  type=refreshAndPersist
                  interval=00:00:00:30


"interval" is not valid for refreshAndPersist.

                  searchbase="dc=company,dc=jp"
                  filter="(objectClass=*)"


That's already the default.

attrs="*" 

The default is "*,+" and you probably should leave it as such.

scope=sub 

That's already the default.

schemachecking=off 

You don't need that.

updatedn="cn=admin,dc=company,dc=jp"

That's not valid for 2.3 syncrepl. If you've actually been reading the documentation, it seems you're reading very old docs. You should make sure you're actually reading the docs that match your code.

                  bindmethod=simple
                  binddn="cn=admin,dc=company,dc=jp"
                  credentials="<secret>"

updateref       ldap://172.20.12.113


My replication test of one worked.

Updating of production servers went without a hitch. (knock on wood).
