I have a wordpress site setup with the wpCAS-w-LDAP plugin for logins. It's working perfectly except for one thing. We have some users who can't login using the CAS system since they don't have an account there (outside our control). Therefore we want to enable some kind of system where the user first is prompted if he/she want to login using CAS or with a standard wordpress account.
Do you know of any plugins like this?
