We are looking at building an application that either proxies a standalone LDAP server or delegates to an embedded Java LDAP instance (ie: ApacheDS, OpenDS) in order to log requests and determine who is accessing which applications on our very large corporate network.
My question is is there a good way to intercept an LDAP request and "pull it apart" or have either OpenDS/ApacheDS push notifications of requests coming into LDAP.
You don't need to do any of that. You can configure LDAP servers to log accesses, either in the LDAP directory itself or elsewhere.
