LDAPv2 should be avoided. LDAPv2 is disabled by default. The most common, however, is: In general, expecting that the sophisticated algorithms implemented by commercial-grade RDBMS would make OpenLDAP be faster or somehow better and, at the same time, permitting sharing of data with other applications.

The short answer is that use of an embedded database and custom indexing system allows OpenLDAP to provide greater performance and scalability without loss of reliability. Now for the long answer.

It is a hard choice and no simple answer exists. However, it is a pig. This is because the data models are very different.

Representing directory data with a relational database is going to require splitting data into multiple tables. Think for a moment about the person objectclass. Its definition requires attribute types objectclass, sn and cn and allows attribute types userPassword, telephoneNumber, seeAlso and description.

All of these attributes are multivalued, so a normalization requires putting each attribute type in a separate table. Now you have to decide on appropriate keys for those tables.

The primary key might be a combination of the DN, but this becomes rather inefficient on most database implementations. The big problem now is that accessing data from one entry requires seeking on different disk areas.

On some applications this may be OK but in many applications performance suffers. The only attribute types that can be put in the main table entry are those that are mandatory and single-value.

You may add also the optional single-valued attributes and set them to NULL or something if not present.

But wait, the entry can have multiple objectclasses and they are organized in an inheritance hierarchy. An entry of objectclass organizationalPerson now has the attributes from person plus a few others and some formerly optional attribute types are now mandatory.

Should we have different tables for the different objectclasses? This way the person would have an entry on the person table, another on organizationalPerson, etc. Or should we get rid of person and put everything on the second table? Should we search all possible tables for matching entries?

Once this point is reached, three approaches come to mind. One is to do full normalization so that each attribute type, no matter what, has its own separate table. The simplistic approach where the DN is part of the primary key is extremely wasteful, and calls for an approach where the entry has a unique numeric id that is used instead for the keys and a main table that maps DNs to ids.

The approach, anyway, is very inefficient when several attribute types from one or more entries are requested. Such a database, though cumbersomely, can be managed from SQL applications. The second approach is to put the whole entry as a blob in a table shared by all entries regardless of the objectclass and have additional tables that act as indices for the first table.

Index tables are not database indices, but are fully managed by the LDAP server-side implementation. However, the database becomes unusable from SQL. And, thus, a fully fledged database system provides little or no advantage. The full generality of the database is unneeded.

Much better to use something light and fast, like LMDB. A completely different way to see this is to give up any hopes of implementing the directory data model. In this case, LDAP is used as an access protocol to data that provides only superficially the directory data model. For instance, it may be read only or, where updates are allowed, restrictions are applied, such as making single-value attribute types that would allow for multiple values.

The nitty-gritty details of LDAP are defined in RFC "The Lightweight Directory Access Protocol (v3) The server responds with an answer and/or with a pointer to where the client can get additional information (typically, another LDAP server).

No matter which LDAP server a client connects to, it sees the same view of the directory; a. 1. Introduction to OpenLDAP Directory Services. This document describes how to build, configure, and operate OpenLDAP Software to provide directory services.
