在CAS 4.2.x中找不到ldaptive模式

Question

I am new to the CAS setup, started using CAS 4.2.x version. With help of the below , doing the setup. [ https://apereo.github.io/cas/4.2.x/installation/LDAP-Authentication.html][1]

After adding bean reference " http://www.ldaptive.org/schema/spring-ext " in the deployerConfigcontext.xml, getting the error

Configuration problem: Unable to locate Spring Namespace handler for xml schema namespace [http://www.ldaptive.org/schema/spring-ext]

Answer 1

I am using CAS 3.5.2 and was facing the same issue ..... the below workaround worked for me. You can give it a shot and see if it works for you as well.

Add the following dependency in your pom.xml file

    <dependency>
         <groupId>org.jasig.cas</groupId>
         <artifactId>cas-server-support-ldap</artifactId>
         <version>${cas.version}</version>
    </dependency>

then remove the below lines from your deployerConfigcontext.xml

xmlns:ldaptive="http://www.ldaptive.org/schema/spring-ext"
http://www.ldaptive.org/schema/spring-ext http://www.ldaptive.org/schema/spring-ext.xsd

In your deployerConfigcontext.xml remove the ldaptive declaration and replace it with the below format.

<bean id="contextSource" class="org.springframework.ldap.core.support.LdapContextSource">
              <!-- DO NOT enable JNDI pooling for context sources that perform LDAP bind operations. -->
              <property name="pooled" value="false"/>

              <!--
                Although multiple URLs may defined, it's strongly recommended to avoid this configuration
                since the implementation attempts hosts in sequence and requires a connection timeout
                prior to attempting the next host, which incurs unacceptable latency on node failure.
                A proper HA setup for LDAP directories should use a single virtual host that maps to multiple
                real hosts using a hardware load balancer.
              -->
              <property name="url" value="your-ldap-url" />

              <!--
                Manager credentials are only required if your directory does not support anonymous searches.
                Never provide these credentials for FastBindLdapAuthenticationHandler since the user's
                credentials are used for the bind operation.
              -->
              <property name="userDn" value="your-userDn-info"/>
              <property name="password" value="password-for-your-userDn"/>

              <!-- Place JNDI environment properties here. -->
              <property name="baseEnvironmentProperties">
                <map>
                  <!-- Three seconds is an eternity to users. -->
                  <entry key="com.sun.jndi.ldap.connect.timeout" value="3000" />
                  <entry key="com.sun.jndi.ldap.read.timeout" value="3000" />

                  <!-- Explained at http://docs.oracle.com/javase/jndi/tutorial/ldap/security/auth.html -->
                  <entry key="java.naming.security.authentication" value="simple" />
                </map>
              </property>
            </bean>

Also in your deployerConfigcontext.xml remove your ldapAuthenticationHandler bean and replace it with the following

<bean class="org.jasig.cas.adaptors.ldap.BindLdapAuthenticationHandler"
              p:filter="your-ldap-filter"
              p:searchBase="your-search-base"
              p:contextSource-ref="contextSource"
              p:ignorePartialResultException="true" />

Please note that i am using CAS 3.5.2 so you might have to make some more changes ...
