Replication configured


When querying the root DSE as any user (or anonymously) -

OUD_INSTANCE_ROOT/bin/ldapsearch -b "" -s base "objectclass=*" +


(where the + sign returns operational attributes)

The replication server shuts down with this error -

When querying cn=changelog replication server will also be shut down-

OUD_INSTANCE_ROOT/bin/ldapsearch -h localhost -p <PORT> -D "cn=<DS_ADMIN>" --bindPasswordFile <PASSWORD_FILE> -b cn=changelog objectclass=* dn
SEARCH operation failed
Result Code: 1 (Operations Error)
Additional Information: An error occurred when accessing the database of the draft change number :


The issue can be reproduced with the following steps:
1. Query root dse returning operational attributes - OR - Query cn=changelog
2. Replication Server shuts down

The issue has the following business impact:
Due to this issue, relying on only one replication server (since this is a two primary server replication config where replication servers are config'd in the same JVM as the DS instances) which prevents HA.
