Hi, The CAS server behaves according to what is defined in its webflow : https://github.com/Jasig/cas/blob/3.5.x/cas-server-core/src/main/java/org/jasig/cas/web/flow/InitialFlowSetupAction.java .
In this case, we'd like to have a login page not displaying the "username" filed is the user is already authenticated (just the password field). You need two changes : - in the webflow, before displaying the login page, add a new expression (around line 128) to evaluate if the user is already authenticated and his username (be aware that the TGT id is in the webflow : https://github.com/Jasig/cas/blob/3.5.x/cas-server-core/src/main/java/org/jasig/cas/web/flow/InitialFlowSetupAction.java, so you would need to query the tickets registry with that) - in the login page, add the appropriate logic : https://github.com/Jasig/cas/blob/3.5.x/cas-server-webapp/src/main/webapp/WEB-INF/view/jsp/default/ui/casLoginView.jsp .
