This layer is pluggable and use the following interfaces: * [PasswordAuthenticator](http://svn.apache.org/repos/asf/mina/sshd/trunk/sshd-core/src/main/java/org/apache/sshd/server/PasswordAuthenticator.java) for password based authentication * [PublickeyAuthenticator](http://svn.apache.org/repos/asf/mina/sshd/trunk/sshd-core/src/main/java/org/apache/sshd/server/PublickeyAuthenticator.java) for key based authentication Those custom classes can be configured on the SSHD server using the following code: :::java SshServer sshd = SshServer.setUpDefaultServer(); sshd.setPasswordAuthenticator(new MyPasswordAuthenticator()); sshd.setPublickeyAuthenticator(new MyPublickeyAuthenticator()); If only one of those class is implemented, only the related authentication mechanism will be enabled. ## JAAS integration SSHD provides a password based authentication that delegates to JAAS. This can be configured in the following way: :::java SshServer sshd = SshServer.setUpDefaultServer(); JaasPasswordAuthenticator pswdAuth = new JaasPasswordAuthenticator(); pswdAuth.setDomain("myJaasDomain"); sshd.setPasswordAuthenticator(pswdAuth); The domain name must be set to the JAAS domain that will be used for authentication.
