+ <p>Kylin will generate intermediate files in HDFS during the cube building; Besides, when purge/drop/merge cubes, some HBase tables may be left in HBase and will no longer be queried; Although Kylin has started to do some <br />
+automated garbage collection, it might not cover all cases; You can do an offline storage cleanup periodically:</p>
+
+<p>Steps:<br />
+1. Check which resources can be cleanup, this will not remove anything:</p>
+
+<div class="highlight"><pre><code class="language-groff" data-lang="groff">export KYLIN_HOME=/path/to/kylin_home
+${KYLIN_HOME}/bin/kylin.sh org.apache.kylin.storage.hbase.util.StorageCleanupJob --delete false</code></pre></div>
+
+<p>Here please replace (version) with the specific Kylin jar version in your installation;<br />
+2. You can pickup 1 or 2 resources to check whether they’re no longer be referred; Then add the “–delete true” option to start the cleanup:</p>
+
+<div class="highlight"><pre><code class="language-groff" data-lang="groff">${KYLIN_HOME}/bin/kylin.sh org.apache.kylin.storage.hbase.util.StorageCleanupJob --delete true</code></pre></div>
+
+<p>On finish, the intermediate HDFS location and HTables should be dropped;</p>

+ <h2 id="enable-ldap-authentication">Enable LDAP authentication</h2>
+
+<p>Kylin supports LDAP authentication for enterprise or production deployment; This is implemented with Spring Security framework; Before enable LDAP, please contact your LDAP administrator to get necessary information, like LDAP server URL, username/password, search patterns;</p>
+
+<h4 id="configure-ldap-server-info">Configure LDAP server info</h4>
+
+<p>Firstly, provide LDAP URL, and username/password if the LDAP server is secured; The password in kylin.properties need be salted; You can run “org.apache.kylin.rest.security.PasswordPlaceholderConfigurer AES your_password” to get a hash.</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>ldap.server=ldap://<your_ldap_host>:<port>
+ldap.username=<your_user_name>
+ldap.password=<your_password_hash>
+</code></pre>
+</div>
+
+<p>Secondly, provide the user search patterns, this is by LDAP design, here is just a sample:</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>ldap.user.searchBase=OU=UserAccounts,DC=mycompany,DC=com
+ldap.user.searchPattern=(&(AccountName={0})(memberOf=CN=MYCOMPANY-USERS,DC=mycompany,DC=com))
+ldap.user.groupSearchBase=OU=Group,DC=mycompany,DC=com
+</code></pre>
+</div>
+
+<p>If you have service accounts (e.g, for system integration) which also need be authenticated, configure them in ldap.service.*; Otherwise, leave them be empty;</p>
+
+<h3 id="configure-the-administrator-group-and-default-role">Configure the administrator group and default role</h3>
+
+<p>To map an LDAP group to the admin group in Kylin, need set the “acl.adminRole” to “ROLE_” + GROUP_NAME. For example, in LDAP the group “KYLIN-ADMIN-GROUP” is the list of administrators, here need set it as:</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>acl.adminRole=ROLE_KYLIN-ADMIN-GROUP
+acl.defaultRole=ROLE_ANALYST,ROLE_MODELER
+</code></pre>
+</div>
+
+<p>The “acl.defaultRole” is a list of the default roles that grant to everyone, keep it as-is.</p>
+
+<h4 id="enable-ldap">Enable LDAP</h4>
+
+<p>Set “kylin.security.profile=ldap” in conf/kylin.properties, then restart Kylin server.</p>
+
+<h2 id="enable-sso-authentication">Enable SSO authentication</h2>
+
+<p>From v1.5, Kylin provides SSO with SAML. The implementation is based on Spring Security SAML Extension. You can read <a href="http://docs.spring.io/autorepo/docs/spring-security-saml/1.0.x-SNAPSHOT/reference/htmlsingle/">this reference</a> to get an overall understand.</p>
+
+<p>Before trying this, you should have successfully enabled LDAP and managed users with it, as SSO server may only do authentication, Kylin need search LDAP to get the user’s detail information.</p>
+
+<h3 id="generate-idp-metadata-xml">Generate IDP metadata xml</h3>
+<p>Contact your IDP (ID provider), asking to generate the SSO metadata file; Usually you need provide three piece of info:</p>
+
+<ol>
+ <li>Partner entity ID, which is an unique ID of your app, e.g,: https://host-name/kylin/saml/metadata</li>
+ <li>App callback endpoint, to which the SAML assertion be posted, it need be: https://host-name/kylin/saml/SSO</li>
+ <li>Public certificate of Kylin server, the SSO server will encrypt the message with it.</li>
+</ol>
+
+<h3 id="generate-jks-keystore-for-kylin">Generate JKS keystore for Kylin</h3>
+<p>As Kylin need send encrypted message (signed with Kylin’s private key) to SSO server, a keystore (JKS) need be provided. There are a couple ways to generate the keystore, below is a sample.</p>
+
+<p>Assume kylin.crt is the public certificate file, kylin.key is the private certificate file; firstly create a PKCS#12 file with openssl, then convert it to JKS with keytool:</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>$ openssl pkcs12 -export -in kylin.crt -inkey kylin.key -out kylin.p12
+Enter Export Password: <export_pwd>
+Verifying - Enter Export Password: <export_pwd>
+
+
+$ keytool -importkeystore -srckeystore kylin.p12 -srcstoretype PKCS12 -srcstorepass <export_pwd> -alias 1 -destkeystore samlKeystore.jks -destalias kylin -destkeypass changeit
+
+Enter destination keystore password: changeit
+Re-enter new password: changeit
+</code></pre>
+</div>
+
+<p>It will put the keys to “samlKeystore.jks” with alias “kylin”;</p>
+
+<h3 id="enable-higher-ciphers">Enable Higher Ciphers</h3>
+
+<p>Make sure your environment is ready to handle higher level crypto keys, you may need to download Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files, copy local_policy.jar and US_export_policy.jar to $JAVA_HOME/jre/lib/security .</p>
+
+<h3 id="deploy-idp-xml-file-and-keystore-to-kylin">Deploy IDP xml file and keystore to Kylin</h3>
+
+<p>The IDP metadata and keystore file need be deployed in Kylin web app’s classpath in $KYLIN_HOME/tomcat/webapps/kylin/WEB-INF/classes</p>
+
+<ol>
+ <li>Name the IDP file to sso_metadata.xml and then copy to Kylin’s classpath;</li>
+ <li>Name the keystore as “samlKeystore.jks” and then copy to Kylin’s classpath;</li>
+ <li>If you use another alias or password, remember to update that kylinSecurity.xml accordingly:</li>
+</ol>
+
+<div class="highlighter-rouge"><pre class="highlight"><code><!-- Central storage of cryptographic keys -->
+<bean id="keyManager" class="org.springframework.security.saml.key.JKSKeyManager">
+ <constructor-arg value="classpath:samlKeystore.jks"/>
+ <constructor-arg type="java.lang.String" value="changeit"/>
+ <constructor-arg>
+ <map>
+ <entry key="kylin" value="changeit"/>
+ </map>
+ </constructor-arg>
+ <constructor-arg type="java.lang.String" value="kylin"/>
+</bean>
+
+</code></pre>
+</div>
+
+<h3 id="other-configurations">Other configurations</h3>
+<p>In conf/kylin.properties, add the following properties with your server information:</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>saml.metadata.entityBaseURL=https://host-name/kylin
+saml.context.scheme=https
+saml.context.serverName=host-name
+saml.context.serverPort=443
+saml.context.contextPath=/kylin
+</code></pre>
+</div>
+
+<p>Please note, Kylin assume in the SAML message there is a “email” attribute representing the login user, and the name before @ will be used to search LDAP.</p>
+
+<h3 id="enable-sso">Enable SSO</h3>
+<p>Set “kylin.security.profile=saml” in conf/kylin.properties, then restart Kylin server; After that, type a URL like “/kylin” or “/kylin/cubes” will redirect to SSO for login, and jump back after be authorized. While login with LDAP is still available, you can type “/kylin/login” to use original way. The Rest API (/kylin/api/*) still use LDAP + basic authentication, no impact.</p>
