SEC-2188: Change CasAuthenticationProvider authenticateNow() method to protected

[spring-projects-issues]

James Lorenzen (Migrated from SEC-2188) said:

I'm trying to enhance CasAuthenticationProvider to add some additional features. Specifically I'd like to override the authenticateNow() method, but it's private and consequently I have to override the authenticate() method as well, which is redundant.
Can you please make the authenticateNow() method protected so one can override it's functionality?
