CAS

CAS is a Java/Tomcat-based single sign on (SSO) project that can integrate with Drupal, Liferay, LDAP and lots more, but unfortunately requires Maven to configure and build.

Could not resolve dependencies for project XXX: Could not find artifact :cas-server-support-ldap:jar

If you just copy the pom.xml as in the instructions to create a WAR Overlay for LDAP authentication:

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

This defines two variables, ${project.groupId} and ${project.version} -- however these refer to your project, not the CAS project. You should instead change this to:

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

LDAP: error code 49 - cannot bind the principalDn.

In this case the problem was that I had set up my principalDn incorrectly:

<bean id="contextSource" class="org.springframework.ldap.core.support.LdapContextSource">
  ...
  <property name="userDn" value="uid=system,ou=admin"/>

The value for userDn should have instead been uid=admin,ou=system (in my case). Embarrased

You should already have been redirected to the CAS server. Click here to continue.

I was getting the following error message:

CAS Authentication wanted!

You should already have been redirected to the CAS server. Click here to continue.
phpCAS 1.2.2 using server https://localhost:8443:8444/cas/ (CAS 2.0)

The key information is that there are two port numbers listed. The problem was that my Drupal configuration had the incorrect port number specified (8444 rather than 8443).
