In the Solaris environment, the FNS implementation currently consists of name services implemented on top of:
Enterprise-level name services such NIS+, NIS, and/or local files. (See "Solaris Enterprise-Level Naming Services", below.)
File naming, printer naming, and support for other applications. (see Chapter 25, Administering File Contexts.)
Global-level naming systems using DNS and X.500/LDAP. (See Chapter 26, FNS and Global Naming Systems.)
FNS will become increasingly more visible to Solaris users as more applications and systems use FNS.
