is a glibc mechanism for providing multiple methods of accessing common databases such as the password or hosts database. It is commonly used to provide an interface to both local <tt>
/etc/passwd</tt>
(and shadow) files, and a remote authentication mechanism such as [NIS] or [LDAP].
-The databases available
for configuration within
the NSS are:
-* aliases: Mail aliases
-* ethers: Ethernet numbers,
-* group: Groups of users
-* hosts: Host names and numbers
.
-* netgroup: Network wide list of host and users
-* networks: Network names and numbers
-* protocols: Network protocols
-* passwd: User passwords
-* rpc: Remote procedure call names and numbers,
-* services: Network services
-* shadow: Shadow user passwords
+The config file
for specifying backend methods for each database is /etc/nsswitch.conf -- see
the nsswitch.conf(5) ManPage
.
-Most of these databases are normally only configured for flatfile access: protocols and services, for example, look up only in /etc/protocols and /etc/services. You could serve these from LDAP, or from a DBM file, or from an SQL database
, or so on.
