NIS+ is the preferred enterprise-wide information service in the Solaris operating environment environment. FNS organization units correspond to NIS+ domains and subdomains. There is one orgunit context for each domain and subdomain.
Under NIS+, FNS context and attribute data are stored in NIS+ tables. These tables are stored in NIS+ directory objects named ctx_dir. There is a ctx_dir directory object for each NIS+ domain and subdomain, residing at the same level as the domain's groups_dir and org_dir directory objects. Thus, the directory object ctx_dir.sales.doc.com. contains FNS tables which store FNS context and attribute data for the sales.doc.com. domain.
Under NIS+, you use FNS and NIS+ commands to work with the information in FNS tables. Do not edit these tables directly or manipulate them with UNIX commands.
