Instance Method Details

#authenticate_with_cas_details(cas_details) ⇒ Object

Given a CAS details hash returned by rack-cas, return the resulting user object. Behavior is as follows:

  • Find a matching user by username (will use find_for_authentication if available).

  • If the user does not exist, but Devise.cas_create_user is set, attempt to create the user object in the database. If cas_extra_attributes= is defined, this will also pass in the extra_attributes hash.

  • Return the resulting user object.
