cas server 3.5.2 with ldap - ldap

Question

I work with cas server 3.5.2 ,
I want to integrate ldap with cas
I make this jar : cas-server-support-ldap-3.5.2.jar and spring-ldap-1.3.1.RELEASE-all.jar under : apache-tomcat-7.0.47\webapps\cas-server-webapp-3.5.2\WEB-INF\lib
I added :
<dependency>
<groupId>org.jasig.cas</groupId>
<artifactId>cas-server-support-ldap</artifactId>
<version>3.5.2</version>
</dependency>
in : apache-tomcat-7.0.47\webapps\cas-server-webapp-3.5.2\META-INF\maven\org.jasig.cas\cas-server-webapp\pom.xml
and I modified apache-tomcat-7.0.47\webapps\cas-server-webapp-3.5.2\WEB-INF\deployerConfigContext.xml

| that fills this role. If you are using some other kind of credentials than UsernamePasswordCredentials, you will need to replace
| DefaultCredentialsToPrincipalResolver with a CredentialsToPrincipalResolver that supports the credentials you are
| using.
|
| Second, AuthenticationManagerImpl uses these resolvers to identify a service requesting a proxy granting ticket.
| In the default configuration, it is the HttpBasedServiceCredentialsToPrincipalResolver that serves this purpose.

Answer 1

My suggestion is:
Create a webapp maven project
Add cas-server-webapp dependency (Take a look here)
Create war using mvn package.
Run cas and test it.
Add cas-server-support-ldap dependency
If you want to modify files, create the same structure in src/main/webapp. Your files will replace cas files.

Answer 2

Change the bean contextSource
<bean id="contextSource" class="org.jasig.cas.adaptors.ldap.util.AuthenticatedLdapContextSource">
....
</bean>
to new way of doing it in version 3.5.2
<bean id="contextSource" class="org.springframework.ldap.core.support.LdapContextSource">
You'll need of course spring-ldap jar, you already have it.
more details here, look for contextSource

Answer 3

Just fixed the same problem on cas 3.5.2+LDAP. You can replace spring-ldap-1.3.1.RELEASE-all.jar with following jar files in ..\WEB-INFO\lib folder for a try.
spring-ldap-core-1.3.2.RELEASE.jar
spring-ldap-core-tiger-1.3.2.RELEASE.jar
