How to add LDAP cache in Spring LDAP?

I want to cache LDAP user data locally to allow faster queries. Do the Spring LDAP offers such a functionality? How can I do this? I am using Spring Security 3.1 and Spring LDAP 1.3.1 for authentication and authorization. It would be nice to have a cache for LDAP using built-in mechanism if exists.. Spring LDAP configuration: applicationContext-ldap.xml: ``` <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jee="http://www.springframework.org/schema/jee" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee.xsd "> <!-- Ldap --> <jee:jndi-lookup id="ldapUrl" jndi-name="appName/ldapUrl" expected-type="java.lang.String" /> <jee:jndi-lookup id="ldapUser" jndi-name="appName/ldapUser" expected-type="java.lang.String" /> <jee:jndi-lookup id="ldapPassword" jndi-name="appName/ldapPassword" expected-type="java.lang.String" /> <!-- for authentication and search purpose --> <bean id="ldapContextSource" class="org.springframework.ldap.core.support.LdapContextSource"> <property name="url" ref="ldapUrl" /> <property name="userDn" ref="ldapUser" /> <property name="password" ref="ldapPassword" /> <property name="pooled" value="true" /> </bean> <bean id="ldapTemplate" class="org.springframework.ldap.core.LdapTemplate"> <property name="contextSource" ref="ldapContextSource" /> </bean> <!-- for pagination search purpose --> <bean id="dirContext" factory-bean="ldapContextSource" factory-method="getReadOnlyContext" scope="session"/> <bean id="singleLdapContextSource" class="org.springframework.ldap.core.support.SingleContextSource" scope="session"> <constructor-arg ref="dirContext"/> </bean> <bean id="singleLdapTemplate" class="org.springframework.ldap.core.LdapTemplate" scope="session"> <property name="contextSource" ref="singleLdapContextSource" /> </bean> </beans> ``` Spring Security configuration: spring-security.xml: ``` <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:security="http://www.springframework.org/schema/security" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.1.xsd"> <!-- This is where we configure Spring-Security --> <security:http auto-config="true" use-expressions="true" access-denied-page="/auth/denied" > <security:intercept-url pattern="/login" access="permitAll"/> <security:intercept-url pattern="/app/admin" access="permitAll"/> <security:intercept-url pattern="/app/common" access="hasRole('User')"/> <security:intercept-url pattern="/viol/home" access="permitAll"/> <security:intercept-url pattern="/app/users" access="permitAll"/> <security:intercept-url pattern="/admin/edit/*" access="hasRole('Administrator')"/> <security:form-login login-page="/auth/login" authentication-failure-url="/auth/loginFailure" default-target-url="/auth/authorize"/> <security:logout invalidate-session="true" logout-success-url="/auth/login" logout-url="/logout"/> </security:http> <security:authentication-manager> <security:ldap-authentication-provider server-ref="ldapContextSource" user-search-filter="(sAMAccountName={0})" user-search-base="dc=myDomain,dc=com" /> </security:authentication-manager> </beans> ``` Thank you very much for your help!
