mod_legacyauth

In the early days of XMPP a custom authentication protocol was used. It is very simple, but not particularly secure (the password is always sent as plain text, so make sure you have encryption required).

However some very old clients and bots may not support the newer (SASL) protocol provided by mod_saslauth. mod_legacyauth provides support for the old protocol.
