Hi Kristian, We have always used the UserDatabaseRealm (tomcat-users.xml) for our user/role database but I believe everything else in the "Restricting Access to Datasets in the TDS" page should apply for an LDAP based authentication realm. You should not have to add a CAS layer into the mix. You will have to make sure you have the correct role names in your LDAP setup and follow the rest of the directions on the "Restricting Access to Datasets in the TDS" page.
