Most of the remainder of the book is dedicated to Part Two - Application Integration. The five chapters in this section cover NIS replacements, Email, Standard Unix Services, LDAP Interoperability and LDAP programming with Perl. I've had to learn most of these topics "the hard way", and finding them all neatly summarised with good examples in a single text is one of the key reasons I wish I'd had this text four years ago. Some of the points this book covers are already outdated, due to the fast-moving development of the projects it refers to, but that can't really be helped, and doesn't overly affect it. The section on NIS replacements is ideal for anyone wishing to use LDAP as a centralised authentication system for unix and windows services, and the LDAP interop chapter covers using LDAP to speak to an Active Directory Server as well, for completeness. The Email chapter covers integration of several different MTAs - sendmail, postfix and exim - and MUAs - pine, mozilla, outlook express, and eudora. Proftpd, apache, samba, freeradius, and lpr are covered by chapter 8, although it's worth noting that lpr support (storing printers in LDAP) relies on a script to generate your printcap for you - I'm not aware of any print spoolers that will support an LDAP backend for configuration just yet. 

  

 The appendices go into greater detail on some specific technologies mentioned earlier, such as [PAM] and [NSS], the OpenLDAP command-line tools, typical LDAP attributes and objects, and a much-needed section detailing slapd ACLs.
