This chapter covers plug-ins that enable Directory Server to handle custom matching rules. The server requires such matching rule plug-ins to support LDAP v3 extensible matching, such as “sounds like” searches.
Code excerpts in this chapter demonstrate a conceptually simple case exact matching scheme. Here, exact matching is a byte comparison between DirectoryString attribute values. Despite the straightforward concept, the plug-in code runs to many lines. The plug-in must provide several functions as well as wrapper functions to enable indexing, searching, and sorting.
Note - You must understand how Directory Server uses matching rule plug-ins before trying to implement your own plug-in. Read this chapter, then read the sample plug-in code. Avoid creating a new matching rule plug-in from scratch.
This chapter covers the following topics:
