- <H1><A NAME="_wmh1_827796637">Unified Name Service</A></H1>
- <P>
- The unified name service (UNS) provides a generic interface to all
- network lookup services. The <VAR>nsd</VAR> daemon, activated at system
- startup time, maintains a shared local cache of all name lookups. When
- presented with a lookup request, it will first check the cache, then
- forward the request on to the appropriate name service.
- </P>
- <P>
- Lookup requests can be passed to more then one name service. The
- order in which name services are to be used is specified in the
- file <VAR>nsswitch.conf</VAR>. This portion of WebForce Internet
- Gateway provides system administrators with an easy way to configure
- the order of name services for each type of network lookup without
- having to edit <VAR>nsswitch.conf</VAR>.
- </P>
- <P>
- The name services that the <VAR>nsd</VAR> daemon currently supports
- include local configuration files, local hash files (DB, MDBM and NDBM
- formats), Network Information Service (NIS), Domain Name Service (DNS),
- and Lightweight Directory Access Protocol (LDAP).
- </P>
- <P>
- Use either of these forms to configure UNS, depending on your
- familiarity with UNS and network name services: </P>
