Red Hat Linux includes several packages that add functionality to LDAP.
The nss_ldap module is an LDAP module for the
Solaris Nameservice Switch (NSS). NSS is a set
of C library extensions necessary for accessing LDAP directory
information, instead of or in addition to the Network
Information Service (NIS) name service and/or flat
files. The nss_ldap module is needed to use LDAP as
a native name service.
The pam_ldap module is needed to integrate LDAP
authentication into the Pluggable Authentication Modules (PAM) API. If
you use pam_ldap, users can authenticate and change
their password using LDAP directories. The nss_ldap
and pam_ldap modules are provided in the
nss_ldap package.
Red Hat Linux also includes LDAP modules for the Apache Web server. The
auth_ldap module is for authenticating HTTP clients
against the user entries in an LDAP directory. The
php-ldap module adds LDAP support to the PHP4
HTML-embedded scripting language. The auth_ldap and
php-ldap modules must be compiled into
Apache as Dynamic Shared Objects
(DSOs) in order to work.
