LDAP Configuration
You will certainly need to use a LDAP server to synchronise members authenticated by CAS in JCMS.
So make sure LDAP is enabled and configured properly.
Try to connect to JCMS with one of your LDAP user account
to make sure the connection and the synchronisation works properly.
CAS configuration
Configuring Properties : Enter the CAS logout URL in the plugin properties.
For example : https://mycas-server.company.com/logout
If this property is not specified, plugin will be disabled !
Configuring CASFilter : Add the CASFilter to your web.xml by following instruction
available on the CAS website :
http://www.ja-sig.org/products/cas/client/javaclient/index.html
Be aware that once this filter is configured, a CAS authentication
will be asked and required, no other authentication will be possible.
