Major Description
the existing name 'JndiLdapRealm' (which should be our default widely-used implementation) was chosen because it uses the JNDI API as an LDAP API. End-users have explained that they overlooked the class because they thought it implied that they needed to be using JNDI (e.g. in an app server) in order to use it.
Because of this confusion, the name should be changed to 'DefaultLdapRealm' to indicate it is our default/common implementation.
