didn t take off, but version 2 did In 1995, LDAPv2 was de ned in RFC 1777, Lightweight Directory Access Protocol Most of the early implementations of LDAP client libraries and gateways trace their lineage to freely available software from the University of Michigan In many of these implementations, a client would use an LDAP client library to talk to an LDAP gateway, which would translate the protocol requests and pass them on to an X500 server

We ve already mentioned that LDAP uses TCP/IP (although it could be made to run on other network protocols) and does not require OSI The encoding of requests and responses also was signi cantly simpli ed X500 allows the data stream of requests and responses to be encoded in many different ways, all of which are variants of the Basic Encoding Rules (BER) speci cation of Abstract Syntax Notation One (ASN1) Although ASN1 is a very powerful and expressive syntax, it requires the client to be capable of interpreting the data types in many different encodings In LDAP, only a small subset of BER is used and required, and most data types are transmitted as strings As a result, LDAP clients do not need to handle the multitude of other encodings and data types required by X500 The authors of LDAP de ned an API for accessing the protocol and assembled an SDK for applications developers X500 lacked a standard client API, which forced client application developers to write most of the code for using the protocol Initially the LDAP speci cations omitted de nitions for data replication, referrals (situations in which a server without the requested information can redirect a client to another server that has the information), access control, chaining (situations in which a server without the requested information contacts another server on behalf of a client), and many other standard X500 features Some of these features have been added to the LDAP speci cations in version 3 or are currently under discussion as proposed additions Other features have been implemented in software from the University of Michigan or from other vendors but have not been standardized Another critical difference between X500 and LDAP is in the understanding of how directories can be combined to form a single globally searchable service The X500 developers envisioned a partition of all directory space in the world on a country basis At the root of the tree in each directory is a null entry that cannot be searched and that has no user attributes It represents a virtual shared root of all directories Under the null node, the directory contains one or more country nodes Under the country nodes, there are organization nodes, which correspond to companies Each company node can contain any structure appropriate to the company Typically this structure consists of a tree of organizational unit nodes, each corresponding to departments or divisions of the company If a request for company information is directed to a particular X500 server, the server can quickly determine that the

requested information is in a different country tree The X500 server can pass the request on to a server for that country, which can then pass it on to a server that holds information for the company requested In reality, it is not feasible to build a global, top-down network of directories in this way, both for practical and for political reasons It is not even practical to use country nodes at the top of the tree of a company directory, since many companies have operations in more than one country LDAP imposes no such restrictions With LDAP, you can build directories from the bottom up to meet the actual needs of an organization You can then make the different organizations appear as a single uni ed organization by setting up referrals between the directories
