Features

Besides clustering, ejabberd also has many other features like a web interface for admins, shared roster, PostgreSQL (ODBC) support, support for virtual domains, nearly XMPP-compliance, a translated interface (including English), LDAP authentication, login via SSL, SASL and STARTTLS. It also supports modules. Most of them provide simple things like for example saving offline messages, but in contrast there are also modules which make more advanced functionalities possible: an IRC-transport to connect with IRC channels, a MUC module, a module for HTTP Polling, a user database module which makes use of user's vCards (saving vCards in LDAP is possible with another module), a module for Publish-Subscribe, and a module to gather statistics via Jabber.
