The pam_ldap module provides the means for workstations to authenticate against LDAP directories, and to change their passwords in the directory. Key Benefits are: * Uses the Pluggable Authentication Module API defined in OSF DCE RFC 86.0. * Can utilize transport layer security (such as SSL or TLS) to encrypt transactions between the workstation and the LDAP server and provide strongly authenticated sign-on. * Shares configuration information with nss_ldap module * Supports ypldapd locator for finding LDAP servers * Supports Netscape Directory Server's password policies and directory-based access authorization.
