I think some of the commands were created to be "manipulating attributes" rather than 'recipe oriented', which leads to this confusion because we do not clearly convey the intent of the action that teh command will execute. A better command syntax here would have been "dsconf instance replication role read-only configure-write-referal", where the the ldif you list would be "dsconf instance query-routing add-remote-referral" or something like that. In this command you have listed, it is setting and controlling the value of nsDS5ReplicaReferral in the replication agreement. This means that a read-only consumer when updated will return a referral to a writable server. The modification you list is about allowing a server which is *not* part of the replication topology to be able to provide referrals to another server that can fufil the request. To demonstrate the two scenarios with an example: [ Write Server A ] -- replication --> [ RO server B ] ^ | ^ | 3. 2. | | 1. | v | \-------------------------------- [ client ] 1. Client writes under (dc=a) to RO server 2. RO Server returns referral to Write Server A 3. Client follows the referral and attempts the write of (dc=a) on A [ Server A (dc=a) ] [ Server B (dc=b) ] ^ | ^ | 3. 2. | | 1. | v | \-------------------------------- [ client ] 1. Client wants to READ or WRITE to (dc=a) on Server B 2. Mapping tree router determines a referral should be sent and responds with referral to Server A 3. Client follows referral and re-attempts on Server A. So I think that really, mapping tree is an ldap router function inside the server, so perhaps it's best to consider it like that, which is why the cli tools were misleading you here sadly. I think we as a team, need to review and understand what happened here to cause them to mislead a person about their function. :( Sorry that this confusion occured.
