Problem using BDB replication in OpenLDAP
Software version:
Berkeley DB: 4.5.20
OpenLDAP:2.3.30
We want to configure the replication management in OpenLDAP's backend
database. All write requests in OpenLDAP master site will spread to
OpenLDAP client site for we have configured the backend database
replication.
We mend the source code the OpenLDAP according to the rep_mgr example
provide by
Berkeley DB.
A test case is executed as follow:
step 1: start openldap server site and client site;
step 2: send write requests to the master site;
step 3: search the master site and ensure the records are inserted in
backend; database successfully;
step 4: search the client site, but not ldap entry is displayed;
step 5: kill the client site process and reboot it;
step 5: search the client site right now after it reboot;
Result: After step 5(reboot the client site), the search results from
client site
is same as the master site.
At step 4: If we intend to insert an entry into the openLDAP server with
BDB client configuration via ldapadd command, it will return "the entry
already exists". After the failed insert operation, if search operation
is executed, one entry will be displayed.Once a insert operation is
tried, the number of entries in the subsequent search will increase by 1.
My question:
Why we can not search any info during the client is normally running? But
once I rebooted the client site, it worked well and could accept search
requests? How to solve this problem:)
