what is a ldap server
LDAP, Lightweight Directory Access Protocol, is an Internet protocol that email and other programs use to look up information from a server. LDAP is mostly used by medium-to-large organiÂ­zations. If you belong to one that has an LDAP server, you can use it to look up contact info and the like. Otherwise, if you were just wondering about this acronym, you probably don't need it. But feel free to read on to learn the story of this bit of Internet plumbing.
