The lightweight Directory access protocol, or ELD, app, as it's called, is used to access directory listings within an Active Directory or from other services. A directory is compiled in hierarchical or logical form, and it is suitable to attach it with the. Domain Name System to allow quick look up and fast resolution queries. The directory generally runs on port 389 and sometimes it is possible to query an ELD app service anonymously. The query can reveal information such as valid usernames that can be further used for performing attacks.
