This refers to a topology deployment that will be able to route URLs without the additional context that the gateway uses for differentiating from one Hadoop cluster to another. This allows the URLs to match those used by existing clients for that may access webhdfs through the Hadoop file system abstraction.</p><p>When a topology file is deployed with a file name that matches the configured de
 fault topology name, a specialized mapping for URLs is installed for that particular topology. This allows the URLs that are expected by the existing Hadoop CLIs for webhdfs to be used in interacting with the specific Hadoop cluster that is represented by the default topology file.</p><p>The configuration for the default topology name is found in gateway-site.xml as a property called: &ldquo;default.app.topology.name&rdquo;.</p><p>The default value for this property is &ldquo;sandbox&rdquo;.</p><p>Therefore, when deploying the sandbox.xml topology, both of the following example URLs work for the same underlying Hadoop cluster:</p>

Some of these configuration elements will need to be customized to reflect your deployment environment.</p><p><strong>main.ldapRealm</strong> - this element indicates the fully qualified classname of the Shiro realm to be used in authenticating the user. The classname provided by default in the sample is the <code>org.apache.shiro.realm.ldap.JndiLdapRealm</code> this implementation provides us with the ability to authenticate but by default has authorization disabled. In order to prov
 ide authorization - which is seen by Shiro as dependent on an LDAP schema that is specific to each organization - an extension of JndiLdapRealm is generally used to override and implement the doGetAuhtorizationInfo method. In this particular release we are providing a simple authorization provider that can be used along with the Shiro authentication provider.</p><p><strong>main.ldapRealm.userDnTemplate</strong> - in order to bind a simple username to an LDAP server that generally requires a full distinguished name (DN), we must provide the template into which the simple username will be inserted. This template allows for the creation of a DN by injecting the simple username into the common name (CN) portion of the DN. <strong>This element will need to be customized to reflect your deployment environment.</strong> The template provided in the sample is only an example and is valid only within the LDAP schema distributed with Knox and is represented by the users.ldif file in the {GATE
 WAY_HOME}/conf directory.</p><p><strong>main.ldapRealm.contextFactory.url</strong> - this element is the URL that represents the host and port of LDAP server. It also includes the scheme of the protocol to use. This may be either ldap or ldaps depending on whether you are communicating with the LDAP over SSL (highly recommended). <strong>This element will need to be customized to reflect your deployment environment.</strong>.</p><p><strong>main.ldapRealm.contextFactory.authenticationMechanism</strong> - this element indicates the type of authentication that should be performed against the LDAP server. The current default value is <code>simple</code> which indicates a simple bind operation. This element should not need to be modified and no mechanism other than a simple bind has been tested for this particular release.</p><p><strong>urls./</strong>** - this element represents a single URL_Ant_Path_Expression and the value the Shiro filter chain to apply to it. This particular sample 
 indicates that all paths into the application have the same Shiro filter chain applied. The paths are relative to the application context path. The use of the value <code>authcBasic</code> here indicates that BASIC authentication is expected for every path into the application. Adding an additional Shiro filter to that chain for validating that the request isSecure() and over SSL can be achieved by changing the value to <code>ssl, authcBasic</code>. It is not likely that you need to change this element for your environment.</p><h4><a id="Active+Directory+-+Special+Note">Active Directory - Special Note</a> <a href="#Active+Directory+-+Special+Note"><img src="markbook-section-link.png"/></a></h4><p>You would use LDAP configuration as documented above to authenticate against Active Directory as well.</p><p>Some Active Directory specific things to keep in mind:</p><p>Typical AD main.ldapRealm.userDnTemplate value looks slightly different, such as  cn={0},cn=users,DC=lab,DC=sample,dc=com

   <li>Trusting the LDAP Server&rsquo;s public key - if the LDAP Server&rsquo;s identity certificate is issued by a well known and trusted certificate authority and is already represented in the JRE&rsquo;s cacerts truststore then you don&rsquo;t need to do anything for trusting the LDAP server&rsquo;s cert. If, however, the cert is selfsigned or issued by an untrusted authority you will need to either add it to the cacerts keystore or to another truststore that you may direct Knox to utilize through a system property.</li>
