I know that LDAP is used to provide some information and to help facilitate authorization.
But what are the other usages of LDAP?
I have had the opportunity to start a project for school about ldap, from scratch, but before getting to know what is ldap, I had to understand what is a directory, there are many (most used directories are novell and windows), here you can see what the directory in Wikipedia.
And ldap is the protocol to communicate with the board, one of the best books I've found is this one.
