All Implemented Interfaces:

MBeanRegistration, org.apache.catalina.Lifecycle, org.apache.catalina.Realm

public final class DavRealm
extends org.apache.catalina.realm.RealmBase

Simple implementation of Realm that consults the Sakai user directory service to provide container security equivalent to then application security in CHEF.

IMPLEMENTATION NOTE: The user is assumed to have all "roles" because servlets and teamlets will enforce roles within Sakai - so in this realm, we simply indicate "true".
