1. LDAP stands for Lightweight Directory Access Protocol. It's a protocol used to communicate with directories, like Active Directory, over the internet. It's lightweight and build primarily for clients. You can use it to authenticate a log-in and get information about a logged-in user (like email, username, any other data stored on the file for that user). It can also be used for things like address books. Understanding LDAP has a good wealth of information about it.
2. You'll need a server that hosts a directory service.
3. If you're using Java, take a look at this: JDNI as LDAP google "LDAP tutorial" and you'll get a wealth of good info.
