## org.jivesoftware.openfire.handler
Class IQAuthHandler

    java.lang.Object
      org.jivesoftware.openfire.container.BasicModule
          org.jivesoftware.openfire.handler.IQHandler
              org.jivesoftware.openfire.handler.IQAuthHandler

All Implemented Interfaces:
  ChannelHandler, Module, IQAuthInfo

    public class IQAuthHandler

extends IQHandler
implements IQAuthInfo

Implements the TYPE_IQ jabber:iq:auth protocol (plain only). Clients use this protocol to authenticate with the server. A 'get' query runs an authentication probe with a given user name. Return the authentication form or an error indicating the user is not registered on the server.

A 'set' query authenticates with information given in the authentication form. An authenticated session may reset their authentication information using a 'set' query.

## Assumptions

This handler assumes that the request is addressed to the server. An appropriate TYPE_IQ tag matcher should be placed in front of this one to route TYPE_IQ requests not addressed to the server to another channel (probably for direct delivery to the recipient).
