There are two major incarnations of OpenLDAP. 2 releases are essentially enhancements or small bug fixes to the original University of Michigan code base and implement only LDAPv2. The OpenLDAP 2 branch is an LDAPv3-compliant implementation. There are several advantages of LDAPv3 over the previous version, such as: • The ability to refer clients to other LDAP servers for information.

Since we have covered the basics, let’s expand Figure 2-1 to create a distributed directory. In a distributed directory, different hosts possess different portions of the directory tree. Figure 2-9 illustrates how the directory would look if the people ou were housed on a separate host. There are many reasons for distributing the directory tree across multiple hosts. These can include, but are not limited to: Performance Perhaps one section of the directory tree is heavily used. Placing this branch on a host by itself lets clients access the remaining subtrees more quickly.
