#This selenium test is to test authentication, by performing the following: create a category and patron (same as basic_workflow.t). Then the superlibrarian logs out and the created patron must log into the staff intranet and OPAC

#Note: If you are testing this on kohadevbox with selenium installed in kohadevbox then you need to set the staffClientBaseURL to localhost:8080 and the OPACBaseURL to localhost:80
