Proxy: server discovery fails silently when proxy base-dn differs from backend's base-dn



      Found with opendj 6.5.0 cc6082ea9b307b39ab4adc5a6ffea28a22993dea

      We set up 2 DJ servers with base_dn=o=example.
      Then we configure a proxy with both servers as static primary servers.
      We create 2 shards, one per server:

      /PROXY/opendj/bin/dsconfig -h nameserver.example.com -p 4446 -D "cn=Directory Manager" -w password -X create-service-discovery-mechanism --mechanism-name "shard1" --type static --set primary-server:nameserver.example.com:1389 -n
      /PROXY/opendj/bin/dsconfig -h nameserver.example.com -p 4446 -D "cn=Directory Manager" -w password -X create-service-discovery-mechanism --mechanism-name "shard2" --type static --set primary-server:nameserver.example.com:1390 -n

      On both DJs, we create an organizational entry ou=People under o=example.
      We create a new proxy backend on it with route-all=False and a base dn of ou=people,o=example:

      /PROXY/opendj/bin/dsconfig -h nameserver.example.com -p 4446 -D "cn=Directory Manager" -w password -X create-backend --backend-name distribute --type proxy --set shard:"shard1" --set shard:"shard2" --set partition-base-dn:"ou=People,o=example" --set proxy-user-password:"password" --set base-dn:ou=People,o=example --set enabled:true --set proxy-user-dn:"uid=proxy,o=example" --set route-all:False -n

      We start over the proxy and it seems fine but yet, in the monitor entry, we cannot find the shards for our backend:

      /PROXY/opendj/bin/ldapsearch -h nameserver.example.com -p 1391 -D "cn=Directory Manager" -w password -b "cn=monitor" "ds-cfg-backend-id=distribute"
      dn: ds-cfg-backend-id=distribute,cn=backends,cn=monitor
      ds-mon-backend-is-private: 0
      ds-mon-backend-proxy-base-dn: ou=People,o=example
      ds-mon-backend-writability-mode: enabled
      objectClass: top
      objectClass: ds-monitor
      objectClass: ds-monitor-backend
      objectClass: ds-monitor-backend-proxy
      ds-cfg-backend-id: distribute

      But no error appear in the logs.

      if I switch the base dn of the proxy to match the naming context of the DJS, (o=example), the discovery works fine.
