The PingDirectory Server provides a means to configure a hub-like, read-only directory server for legacy systems that require it. The read-only directory server participates in replication but cannot respond to any update requests from an external client. You can configure the Directory Server by setting the writability mode to internal-only, which makes the server operate in read-only mode. Read-only mode directory servers can process update operations from internal operations but reject any write requests from external clients. Because the Directory Server cannot accept write requests, you can configure the server to send a referral, which redirects a client's request to a master server. The client must perform the operation again on the server named in the referral.
Note: For Implementers of Third Party Extensions. Many Server SDK extensions use the
InternalConnectioninterface to process operations in the server, rather than issuing LDAP requests over the network. If an extension does so in response to an external update request, then any Directory Server using that extension will effectively respond to external update requests, even though the Directory Server is configured to operate in read-only mode, as described above. One possible workaround is to split the extension into two extensions, one for reads and one for writes, then disabling (or not deploying) the write-only extension when configuring a Directory Server in read-only mode.
