Trevor Pounds updated AMQ-358:
------------------------------

    Attachment: LdapNetworkConnector.java.svn.diff

Contributing patch. This patch was tested with ActiveMQ trunk, ApacheDS 1.0.2.

ActiveMQ LDAP network connector can be configured via XBean. In order for an LDAP entry to be valid to work with this connector the entry must implement the ipHost and ipService objectClasses as defined in RFC2307.  This is easily configurable when using ApacheDS with Apache Directory Studio.  Though this is beyond the scope of describing this patch.

Example 1:
connects to the ldapserver with the provided credentials. And will search one level deep from the base and below and connect to all entries below that match the given filter. In this case entries that have cn=cluster0* as an attribute. Where * matches any number of characters.

<networkConnectors>
      <ldapNetworkConnector uri="ldap://myldapserver:10389"
                            base="ou=servers,ou=activemq,o=apache"
                            user="uid=admin,ou=system"
                            password="secret"
                            searchFilter="(cn=cluster0*)"
                            searchScope="ONELEVEL_SCOPE"
                            />
</networkConnectors>

Example 2:
connects to the ldapserver with the provided credentials. And will search the entire subtree from the base and below and connect to all entries below that match the given filter. In this case entries that have cn=server* as an attribute. Where * matches any number of characters.

<networkConnectors>
      <ldapNetworkConnector uri="ldap://myldapserver:10389"
                            base="ou=servers,ou=activemq,o=apache"
                            user="uid=admin,ou=system"
                            password="secret"
                            searchFilter="(cn=server*)"
                            searchScope="SUBTREE_SCOPE"
                            />
</networkConnectors>

To get a better understanding of what filters are allowed in LDAP please see RFC2254. For more information on the usage of the searchScope attribute please refer to the javax.naming.directory.SearchControls object that was introduced in Java v 1.3.  Upon acceptance of the patch I will gladly update the ActiveMQ documentation to cover more advanced usage of the ldapNetworkConnector configuration, though it should be fairly simple to use by anyone that has limited experience with LDAP and JNDI.

> It'd be nice to use a clustered JNDI or LDAP server to perform discovery of networks, clusters etc
