nss-pam-ldapd is a Name Service Switch module and Pluggable Authentication Module using an LDAP server. It allows your LDAP server to provide user account, group, host name, alias, netgroup, and almost any other information that you would normally get from /etc flat files or NIS, and allows you to do authentication to an LDAP server.
Ldap Synchronization Connector reads from any data source including databases, LDAP directories, or files and transforms and compares this data to an LDAP directory. These connectors can then be used to continuously synchronize a data source to a directory, for a one shot import, or to compare differences by outputting CSV or LDIF format reports. It offers a powerful transformation engine based on a scripting language to easily manipulate data on the fly. Various identity management functions are included for directory-specific compatibility - most notably Active Directory (changing passwords, account status, last logon, etc.).
Clement is an email server application. Its main function is to block unwanted mail (spam) as soon as possible in the email exchange process. It accepts or rejects email while the SMTP session, initiated by the email sender, is still pending, accepting legitimate email messages without the need to return an error status to non-existent or "borrowed" return address later. Clement can operate in two modes, either as a standard MTA (as sendmail, Postfix, Exim, Exchange, etc.) to store email in the recipient's own area, or to transmit the mail to an another SMTP server acting as smart spam filtering device. Each email domain name Clement knows about can be treated in one of these two modes depending on the group to which the domain name has been set. Each message is verified by a virus scanner (ClamAV) while the SMTP connection is still open, but the refusal of mail and the reason for refusal is notified to the actual sender. Mail management is done via a Web interface and can be delegated to three administrative levels (Root-Admin, Group-Admin, Domain-Admin). Standard users can access their own logs (sent email status, email rejected, quarantined email, etc.). With this interface, the user can handle the rejection and acceptance of mail. Users who are level "Admin" can access the session logs (via the Web interface). Clement uses a SQL database (PostgreSQL, MySQL) to store and manage logs, user profiles, and dynamic management of directives concerning the sender-receiver relationship.
389 Directory Server (formerly Fedora Directory Server) is a full-featured LDAPv3 compliant server. In addition to the standard LDAPv3 operations, it supports multi-master replication, fully online configuration and administration, chaining, virtual attributes, access control directives in the data, Virtual List View, server-side sorting, SASL, TLS/SSL, and many other features. The transactional Berkeley DB 4.2 is used as its data store and a full plug-in API allows developers to extend the the functionality of the server in many ways, and many of the core features of the server are already implemented using this API. The server is very mature, having started out as Netscape Directory Server.
