20 * Wrapper class for <code>org.apache.shiro.realm.ldap.JndiLdapRealm</code>.
21 * This implementation disables Authorization so any LDAP user is able to access
22 * server resources. This is particularly useful for quickly prototyping ODL
23 * without worrying about resolving LDAP attributes (groups) to OpenDaylight
27 * The motivation for subclassing Shiro's implementation is two-fold: 1) Enhance
28 * the default logging of Shiro. This allows us to more easily log incoming
29 * connections, providing some security auditing. 2) Provide a common package in
30 * the classpath for ODL supported Realm implementations (i.e.,
31 * <code>org.opendaylight.aaa.shiro.realm</code>), which consolidates the number
32 * of <code>Import-Package</code> statements consumers need to enumerate. For
33 * example, the netconf project only needs to import
34 * <code>org.opendaylight.aaa.shiro.realm</code>, and does not need to worry
35 * about importing Shiro packages.
