Provides a Name Service Switch (NSS) module that allows your LDAP
server to provide user account, group, host name, alias, netgroup, and
basically any other information that you would normally get from /etc
flat files or NIS. It also provides a Pluggable Authentication Module
(PAM) to do authentication to an LDAP server.
This is implemented using thin NSS and PAM modules which delegate to a
dedicated service (nslcd) that queries the LDAP server with persistent
connections, authentication, attribute translation, etc.
