After successfully building the cas war with the defaults provided in the overlay template, I have been attempting to add LDAP support but have run into trouble.
-- By following the instructions at: http://jasig.github.io/cas/4.1.x/installation/LDAP-Authentication.html
I added the cas-server-support-ldap dependency to my overlay pom.xml file.
The overlay build succeeds however running the web app with jetty (as described in the overlay template readme) now provides two errors:
The first is:
java.lang.IllegalStateException: Duplicate fragment name: spring_web for jar:file:///C:/dev/cas-overlay-template/target/tmp/cas-server-webapp-4_1_3_war1/WEB-INF/lib/spring-web-4.1.8.RELEASE.jar!/META-INF/web-fragment.xml and jar:file:///C:/Users/labin/.m2/repository/org/springframework/spring-web/4.1.8.RELEASE/spring-web-4.1.8.RELEASE.jar!/META-INF/web-fragment.xml

I have noticed that the fork-web.xml file generated when running jetty is 0 length now whereas before adding the ldap dependency this was not the case.

Pull from Jasig repo’s master again, and merge. Problem should go away.

Worked thanks.
Was this a known issue that was fixed since when I originally checked out the overlay?
What fixed the issue?

Likely, yes. The issue is with the embedded jetty in that it disallows duplicate/multiple web fragments. The fix tells jetty to not look in other places and only rely on the CAS web.xml file.
