In this chapter we have examined several strategies for configuring LDAP servers to work cooperatively. We first looked at synchronizing and replicating a directory information tree from a master directory to one or more shadow (subordinate) directory servers using SyncRepl.
After looking at replication we turned to proxying, and looked at three different proxy configurations: the simple proxy, a caching proxy, and a transparent proxy.
This chapter concludes our detailed look at the OpenLDAP server suite. Next we will turn to the tasks of integrating LDAP and extending applications to make use of directory data. Most of the applications we will examine use the OpenLDAP libraries to implement their LDAP functionality.
