Login Dropdown

We are using the Authorizer plugin to enable CAS for our site. Is there a way to have the login drop-down removed and, instead just have it direct to wp-login.php? For some reason, the login with CAS button does not work in the dropdown, but does on the wp-login.php. I tried to hide the login and do a custom menu linking to the php page, but could not get that to work using below in customize>custom css header .topmenu a.smallimg.vbplogin[href="#login"] {display:none;}
