28.4 Extending NSS

One of the advantages of NSS mentioned above is that it can be extended quite easily. There are two ways in which the extension can happen: adding another database or adding another service. The former is normally done only by the C library developers. It is here only important to remember that adding another database is independent from adding another service because a service need not support all databases or lookup functions.

A designer/implementor of a new service is therefore free to choose the databases s/he is interested in and leave the rest for later (or completely aside).
