Before I activated the plugin, I added a user (administrator) with my university username and password. I want to use wpcas to switch authentication to our university's system. Once I activated and configured the settings, it worked. The only problem is that I can't add another user because there is no box for password. This is a problem for obvious reasons, but my password must be changed every 3 months, so I can't change it if there's no place for a password. Can anyone help?
